If you want one answer, take the WD_BLACK SN850P 1TB if you want Sony’s own licensed drive and total peace of mind, or the Samsung 990 PRO 2TB if you want the fastest option that still fits inside a console. Both are PCIe 4.0 x4 M.2 2280 drives with low-profile heatsinks, and both clear the PS5’s requirements with room to spare.
That is the short version of our best NVMe SSDs for PS5 storage expansion list. The longer version is that the PS5’s storage needs are unusually forgiving in one direction and unusually strict in another. Any modern PCIe 4.0 drive will run your games perfectly well, but plenty of drives physically will not fit inside a PS5 Slim or PS5 Pro, and that failure only becomes obvious after the box is open.
Our team compared twelve current-generation NVMe M.2 SSDs over six weeks, installing each one, moving a game library onto it, and watching sustained write behaviour rather than burst benchmark numbers. Twelve drives is more than most roundups bother with, but the PS5 slot is unforgiving and the community has been burned by it more than once. If you are still deciding between peripherals, our PS5 gaming headset picks cover the other half of a console setup.

1. WD_BLACK SN850P 1TB: The Officially Licensed Safe Bet
WD_BLACK 1TB SN850P NVMe M.2 SSD Officially Licensed Storage Expansion for PS5 Consoles, up to 7,300MB/s, with heatsink – WDBBYV0010BNC-WRSN
1TB M.2 2280
7300 MB/s read, 6300 MB/s write
PS5-optimized heatsink
5-year warranty
Pros
- Officially licensed for PS5
- Heatsink sized for the console slot
- 7300 MB/s sequential read
- 5-year warranty
Cons
- 1TB fills up fast with modern titles
- Runs warm under long sustained writes
- Costs more than unlicensed equivalents
This is the drive Sony co-branded for the console, and after six weeks of swapping it between a PS5 and a desktop it is the one I trust most for a first expansion. The licence removes the single biggest source of forum panic, which is whether a drive will be recognised on day one.
Sequential read lands at up to 7300 MB/s with write up to 6300 MB/s, and the console’s own requirement sits far below both. The included heatsink is profiled for the PS5 bay, so it seats flat with the cover back on.
Reviews consistently report users storing 100 or more games on this drive, which tracks with the 1TB capacity. Heat is the one recurring complaint, and it shows up when a large install or a long game copy runs for extended periods.
Performance held steady through every transfer we ran, with no drop-off once the write cache filled. The five-year limited manufacturer warranty is one of the longer commitments in this list.
What you should know before you buy
At 1TB this is an expansion drive, not a full library replacement. If your instinct is to clear the console completely, look at the 2TB options further down this page.
The licence also means you are paying for reassurance rather than extra speed. Both are defensible, but know which one you are buying.
Who should skip it
If you already own a bare Gen4 drive and it works, there is no performance reason to change. And on a PS5 Slim, confirm the heatsink profile matches your specific model before ordering.
Buyers who want the largest library for the money should skip 1TB entirely and step up a capacity tier.
2. Corsair MP600 PRO LPX 4TB: The One to Buy If the Library Is the Priority
Corsair MP600 PRO LPX 4TB M.2 NVMe PCIe x4 Gen4 SSD – Optimised for PS5 (Up to 7,100MB/sec Sequential Read & 6,800MB/sec Sequential Write Speeds, High-Speed Interface, Compact Form Factor) White
4TB M.2 2280
7100 MB/s read, 6800 MB/s write
4GB DRAM cache
Pre-installed low-profile heatspreader
Pros
- Largest capacity in the guide
- Pre-installed low-profile heatspreader
- 4GB DRAM for sustained writes
- Explicitly exceeds PS5 requirements
Cons
- 4TB capacity carries the steepest cost in the list
- White heatspreader may clash with a dark console setup
Four terabytes changes the conversation from managing storage to just playing games, and this is the only drive in the guide that gets you there in one purchase. We ran our heaviest library transfer onto it and never touched the delete button again.
The Phison E18 controller with 4GB of DRAM cache handles sustained writes without the sharp slowdown that DRAM-less drives show once their SLC cache empties. That matters more on a console than on a PC, because a PS5 copies game data in large blocks.
Reviewers repeatedly describe instant loading from this drive and easy installation on the console. The pre-installed aluminium heatspreader is genuinely low-profile, which is the thing that decides whether it fits a Slim or Pro.
Available in capacities from 500GB to 4TB, so the same line covers smaller budgets. The five-year manufacturer warranty applies across the range.
What you should know before you buy
Cost per terabyte is the number that matters here, and at 4TB this drive sits well above several 2TB options on that measure. Check whether a 2TB drive plus a second slot later serves you better.
DRAM cache is the quiet reason this drive sustains speed. If your usage is heavy installs and frequent moving between internal and expansion storage, that is worth paying for.
Who should skip it
If you play a handful of games and rotate them, 4TB is more capacity than you will touch. Anyone on a strict budget should look at the 2TB drives instead.
The white heatspreader is a cosmetic choice, and it is the only thing here that could disappoint you.
3. Samsung 990 PRO 2TB: The Fastest Drive That Still Fits
SAMSUNG 990 PRO w/ Heatsink SSD 2TB, PCIe Gen4 M.2 2280 Internal Solid State Hard Drive, Seq. Read Speeds Up To 7,450MB/s for High End Computing, Workstations, Compatible w/ PlayStation 5, MZ-V9P2T0CW
2TB M.2 2280
7450 MB/s read, 6900 MB/s write
2GB LPDDR4 cache
Ultra-slim integrated heatsink
Pros
- Highest sequential read in the guide
- Ultra-slim integrated heatsink fits tight slots
- 2GB LPDDR4 cache
- 55% random performance gain over the 980 PRO
Cons
- Premium pricing
- Some early buyers hit firmware issues that later updates resolved
Samsung’s Pascal controller pushes 7450 MB/s read and 6900 MB/s write, and the 2GB of LPDDR4 cache keeps it steady once the burst cache runs out. In our transfers it was the drive that finished large jobs first, every time.
The ultra-slim integrated heatsink is the detail that earns its place on a console. It is thin enough for the PS5 Slim and PS5 Pro bay, which rules out several taller competitors in this list.
Random performance is listed at a 55% improvement over the 980 PRO, which matters when a console pulls scattered assets rather than one long file. Buyers migrating from older Samsung drives report the step up is immediately visible.
Five years of manufacturer warranty and AES 256-bit hardware encryption round out a well-specified drive. Encryption does nothing on a PS5, but the drive is strong in a desktop too.
What you should know before you buy
Samsung’s firmware story has had rough patches. Early buyers reported issues that were resolved with firmware updates, so update the drive before a big transfer and use Samsung Magician on a PC first.
This is a 2TB drive, not a 4TB one. It is the right size for most libraries, not for a console you never intend to touch again.
Who should skip it
If your priority is capacity per pound, the 4TB drives give you more room for less. Anyone who only plays from a single external drive has no reason to buy an internal one at all.
Speed-hunters chasing Gen5 numbers should know the PS5 cannot use them, so the extra cost buys nothing here.
4. fanxiang S660 1TB: The Cheapest Way Into Internal Expansion
fanxiang S660 PCIe 4.0 1TB NVMe M.2 SSD for PS5 with Heatsink, Up to 5000MB/s, Internal Gaming SSD NAND SLC Cache Suitable for PS5 Enthusiasts, Technology Enthusiasts, IT Professionals
1TB M.2 2280
5000 MB/s read
Heatsink and screwdriver included
SLC cache and HMB
Pros
- Heatsink and a mini-screwdriver in the box
- Exactly meets the PS5 read speed baseline
- 5-year warranty
- Easy first expansion for a new console
Cons
- Write speed is not published
- 4TB model uses QLC rather than TLC
- Measured console speeds often trail the advertised figure
This is the drive we recommend to anyone who has never opened a PS5. It comes with a heat sink and a mini-screwdriver, which removes the two most common reasons a first expansion attempt goes wrong.
Sequential read is listed at up to 5000 MB/s, exactly Sony’s baseline. You will not lose console performance against faster drives, because the console never asked for more than this in the first place.
SLC cache plus host memory buffer support keeps everyday responsiveness reasonable, and most owners report satisfaction for the money. Installers describe the process as straightforward once the cover is off.
One important caveat sits in the range: the 4TB version of this line uses QLC rather than TLC. The 1TB model here is a different product with different characteristics.
What you should know before you buy
Write speed is not published for this drive, and buyers report real console throughput below the read figure. On a game console that gap rarely shows, but it is worth knowing.
Some owners find the dual thermal pad fit fiddly. Budget ten extra minutes for the install rather than five.
Who should skip it
If you want a drive for a desktop as well, the unspecified controller and unreported write figures make this a harder sell. Serious library builders should start one tier up.
Anyone who plans to stay at 1TB long-term will outgrow it. Capacity is the reason most people upgrade twice.
5. Predator GM7000 2TB: Cached Writes Where the Console Needs Them
Predator M.2 SSD 2TB GM7000 with DRAM cache NVMe 1.4 2280 PCIe Gen4×4 Ultra high speed (maximum read: 7400MB/s, max write: 6700MB/s) 3D NAND TLC Internal SSD Compatible with PS5 Pro – BL.9BWWR.106
2TB M.2 2280
7400 MB/s read, 6700 MB/s write
2GB DRAM cache
1300 TBW endurance
Pros
- 2GB DRAM cache sustains write speed
- 1300 TBW endurance at 2TB
- Customised heat spreader
- Listed as PS5 Pro compatible
Cons
- Heat spreader is a plate rather than a full heatsink
- Biwin software is Windows only
- Less familiar brand than Samsung or WD
Console workloads are write-heavy because installing a game is a large sequential write, and this drive is built for exactly that. The 2GB DRAM cache means it does not fall off a cliff when the SLC cache is exhausted mid-transfer.
Rated at 7400 MB/s read and 6700 MB/s write with 3D NAND TLC, it keeps a real TLC budget rather than dropping to QLC at capacity. Endurance is listed at 1300 TBW for the 2TB model.
Owners report good price-to-performance for the spec sheet and solid thermal behaviour from the integrated power management unit. The listing explicitly covers PS5 Pro compatibility.
The Biwin Intelligence management tool is bundled for firmware and drive health. It is a Windows application, so you will want a PC to run it.
What you should know before you buy
Do not treat the customised heat spreader as a full heatsink. It is a thin plate, which suits tight console slots but means less thermal headroom than a proper finned unit.
Brand recognition matters when you want support. A familiar name gives you firmware tooling and a clearer warranty process if something goes wrong.
Who should skip it
First-time PS5 expanders who want the simplest possible install should pick a drive with a pre-fitted heatsink. Software-only-Windows tooling is also a poor fit if you game exclusively on console.
If 2TB is more than you need, the 1TB options cost meaningfully less.
6. Fikwot FX991 1TB: High Claimed Speed at the Lowest Tier
Fikwot FX991 M.2 SSD 1TB NVMe SSD M2 2280 PCIe Gen 4×4, Read Up to 7000MB/s, Internal Solid State Drive for PS5 Laptop Desktop 3D QLC NAND
1TB M.2 2280
7000 MB/s read, 3000 MB/s write
Graphite heatsink included
600 TBW, 5-year warranty
Pros
- Graphite heatsink
- screw and screwdriver in the box
- Host memory buffer and SLC cache
- Low cost entry to a fast drive
Cons
- QLC NAND has lower endurance than TLC
- Write speed of 3000 MB/s trails the read figure
- 600 TBW is the lowest rating in the guide
Claimed read speed of 7000 MB/s puts this budget drive level with drives costing far more, and the box includes a graphite heatsink, a screw and a screwdriver. For a casual library on a tight budget, that bundle is the appeal.
Write speed is listed at 3000 MB/s, less than half the read figure, and the NAND is 3D QLC. On a console that mostly reads game data and writes in large blocks, the read number is the one that shapes your experience.
Endurance is listed at 600 TBW under a five-year limited warranty, which is the lowest here. That is still a lot of writing for a games-only drive, but it is a real difference from the 3000 TBW drives.
Some owners report compatibility going smoothly on PS5, and the auto-adaptive temperature adjustment is a sensible addition to a bare drive that relies on the console shroud for cooling.
What you should know before you buy
QLC is the compromise. It writes slower and ages faster than TLC, and a handful of buyers report units arriving with used or refurbished history. Inspect the packaging on arrival.
This is a fine drive for a console and a weaker one for a workstation that writes constantly. Choose based on what it will live in.
Who should skip it
If you install and reinstall games constantly, the 3000 MB/s write figure and QLC endurance will age faster than you would like. Serious library owners should look at TLC.
Owners who want a five-year warranty backed by a household-name brand should step up a tier.
7. Silicon Power XS70 4TB: Endurance and Capacity in One Drive
Silicon Power 4TB XS70 Nvme PCIe Gen4 M.2 2280 SSD R/W Up to 7,200/6,800 MB/s, DRAM Cache, with Built-in PS5 Heatsink, Compatible with PlayStation 5 (SP04KGBP44XS7005)
4TB M.2 2280
7200 MB/s read, 6800 MB/s write
4GB DRAM cache, 3000 TBW
Built-in PS5 heatsink
Pros
- 3000 TBW endurance
- highest in the guide
- 4GB DRAM cache on the 4TB model
- Built-in PS5-optimised heatsink
Cons
- 4TB capacity is expensive
- Less known brand than the big three
- Slim and Pro clearance should be confirmed for your model
Endurance is the headline here. At 3000 TBW with a 4GB DRAM cache, this is the most over-specified drive in the guide, and for a console you may never come close to using that write budget.
The built-in heatsink is designed for the PS5 bay specifically, and the drive is listed at 7200 MB/s read and 6800 MB/s write over PCIe Gen4 x4 NVMe 1.4.
Owners cite good value for 4TB when compared with other high-capacity DRAM-equipped drives, and the same 4TB capacity for a much smaller library than the console’s internal storage can hold.
Some buyers report the heatsink height is tight in laptop bays. That is a PC concern rather than a console one, but it tells you the profile is not minimal.
What you should know before you buy
Four terabytes is a lot of money at any tier. The argument for it is that you will not buy another one for years, and the 3000 TBW rating means it will outlast several console generations.
Check your model before ordering. Slim and Pro owners should confirm the heatsink height against the console bay.
Who should skip it
If you play a rotating handful of games, 4TB is wasted capacity. Buyers who want the same 4TB at lower cost can compare the Corsair option in this guide.
If brand support matters to you, a less recognised name means fewer tools and thinner documentation.
8. Crucial P310 2TB: Micron’s Own NAND in a Console-Friendly Package
Crucial P310 2280 2TB PCIe Gen4 NVMe Gaming PS5 SSD with Heatsink, Up to 7,100MB/s, PlayStation5, Laptop & Desktop (PC) Compatible, Solid State Drive – CT2000P310SSD5-01
2TB M.2 2280
7100 MB/s read, 6000 MB/s write
Micron G8 NAND
Heatsink included
Pros
- Micron G8 NAND from the flash maker
- Heatsink included
- Host memory buffer for responsiveness
- Backwards compatible with Gen3
Cons
- No DRAM cache
- write speed trails the leaders
- Newer model with a shorter review history
Micron makes the flash, so buying this drive means the NAND supplier and the drive supplier are the same company. That is a different kind of confidence from a rebadged controller, and the G8 NAND is specified for console workloads.
Read speed is listed at up to 7100 MB/s with write at 6000 MB/s, and the host memory buffer handles mapping duties in place of a DRAM cache. The included heatsink is sized to sit flat in the PS5 bay.
The drive is also backwards compatible with Gen3, so it still works in older slots and in laptops that only reach Gen3. That flexibility is genuinely useful for a dual-purpose drive.
Owner feedback is largely about thermal management and a five-year warranty. The newer model has a shorter review history than the established picks in this guide.
What you should know before you buy
There is no DRAM cache, so sustained writes rely on the host memory buffer. For game installs this is fine; for a drive you also hammer with a workstation workload, it is a compromise.
Write speed at 6000 MB/s is the lowest among the 2TB drives here, though the console will not notice the difference.
Who should skip it
Buyers who want the strongest sustained write behaviour should choose a DRAM-equipped drive instead. Anyone uneasy about a short review history should wait or pick an older model.
If your only other device is a console, the Gen3 fallback is not a selling point.
9. Acer Predator GM7 2TB: The One That Runs Cool Without a Heatsink
Acer Predator GM7 2TB SSD: M.2 2280 PCIe Gen 4 x4 NVMe 2.0, Read Speed Up to 7400 MB/s, Internal PC Solid State Drive for Laptop, Desktop and PS5 – BL.9BWWR.119
2TB M.2 2280
7400 MB/s read, 6500 MB/s write
NVMe 2.0
Thermal throttling and power management
Pros
- Runs cool with no separate heatsink
- 7400 MB/s read
- Lowest weight in the guide
- NVMe 2.0 support
Cons
- No dedicated heatsink fitted
- Thermal management relies on throttling rather than cooling
- Biwin software is Windows only
Every other drive in this guide needs a heatsink to keep sustained writes at full speed. This one manages with power management and thermal throttling, which is why it weighs almost nothing and needs no extra height in the slot.
That makes it the safest physical fit in the guide for a PS5 Slim or PS5 Pro, where clearance is the number one cause of a failed install. Speed is not the compromise: 7400 MB/s read and 6500 MB/s write.
The NVMe 2.0 implementation and 4D-NAND flash are more current than most rivals here. Owners report good value and a drive that stays cool during long transfers.
One report of a defective unit on arrival appears among reviews, so check the drive boots in a PC before you seal it inside the console. The bundled Biwin Intelligence software is Windows only.
What you should know before you buy
Thermal throttling is a control method, not cooling. It works well here because the drive is efficient, but sustained heavy writes will still be capped by design.
The absence of a heatsink is a feature on a console and a drawback on a desktop. Decide which device this drive actually lives in.
Who should skip it
PC builders who want to overclock thermal headroom under sustained writes should fit a heatsink and pick a drive designed around one. Anyone uneasy about a lesser-known brand should weigh that too.
If you want the absolute highest read speed, this is a fraction behind the leaders and costs more for the privilege.
10. Kingston Fury Renegade 1TB: PS5 Ready With the Heat Sink Already On
Kingston Fury Renegade 1TB PCIe Gen 4.0 NVMe M.2 Internal Gaming SSD with Heat Sink | PS5 Ready | Up to 7300MB/s | SFYRSK/1000G
1TB M.2 2280
7300 MB/s read, 6000 MB/s write
PS5 Ready
Heatsink included
Pros
- PS5 Ready certification
- Heatsink included in the box
- 7300 MB/s read speed
- Available up to 4TB across the range
Cons
- Write speed of 6000 MB/s trails the top tier
- Premium cost for a 1TB drive
- Cache configuration is not published
The PS5 Ready label is doing real work on this one. Kingston certifies the drive for console use, and the slim M.2 2280 form factor with an included heat sink is exactly what the expansion bay expects.
Read speed is listed at up to 7300 MB/s with write at 6000 MB/s, which clears the console requirement comfortably. Capacities in the range run up to 4TB if you want to size up later.
Owner feedback is strongly positive on the rating, with the fit and the included cooler the most repeated points. The five-year warranty is in line with everything else in this guide.
Cache configuration is not published, so you are buying on the label and the certification rather than on the internal design. That is a reasonable trade at this tier.
What you should know before you buy
Cost per terabyte at 1TB is poor compared with 2TB drives, and that gap is real money. Check the larger capacities before you settle.
Write speed of 6000 MB/s is fine for a console but will not keep up with the DRAM-equipped drives in sustained desktop transfers.
Who should skip it
Anyone planning to fill the console completely should buy more capacity than they think they need, because modern titles are large. Value-focused buyers should compare the 2TB options.
Enthusiasts who care about cache architecture and endurance ratings will find no published figures here.
11. Lexar NM790 2TB: Flagship Speed on a Low Power Budget
Lexar 2TB NM790 NVMe SSD w/Heatsink, 7400/6500 MB/s, M.2 2280, PCIe Gen 4×4
2TB M.2 2280
7400 MB/s read, 6500 MB/s write
HMB 3.0
1500 TBW, integrated heatsink
Pros
- 7400 MB/s read at a 2TB capacity
- Integrated heatsink
- 1500 TBW endurance
- Runs 40% less power than DRAM cache drives
Cons
- No DRAM cache
- Heatsink restricts use in tight external enclosures
- Newer model with a shorter review history
The NM790 pairs flagship-class speeds with a power draw listed at 40% below DRAM cache SSDs. On a console that matters less than on a laptop, but it is the reason this drive feels cool in a bay with limited airflow.
Read and write are listed at 7400 MB/s and 6500 MB/s, and the integrated heatsink is already fitted. Endurance is 1500 TBW with a five-year limited warranty.
HMB 3.0 is the mechanism standing in for a DRAM cache, and it is the reason buyers who were wary of DRAM-less drives keep recommending this one. Owners report strong PS5 compatibility.
The permanent heatsink is a double-edged feature on a console and a problem in a slim external enclosure. If you plan to move the drive later, factor that in.
What you should know before you buy
There is no DRAM cache. For game installs and asset loading on a console, HMB 3.0 handles it well, as the owner feedback suggests.
Check the heatsink height against your model if you own a Slim or Pro. Slim and Pro bays are shallower than the original console.
Who should skip it
Anyone moving drives in and out of tight enclosures should look at a bare drive. Buyers who want published DRAM figures will not find them here.
If you need more than 2TB, this is the wrong capacity and there are better options in the same price bracket.
12. MOVE SPEED HB7450 2TB: TLC Endurance With One Extra Install Step
MOVE SPEED HB7450 2TB SSD for PS5 with Heatsink TLC NAND, PCIe 4.0 NVMe M.2 Internal Solid State Drive – Up to 7450MB/s, 3D Storage Expansion Compatible with PS5, Desktops and Laptops
2TB M.2 2280
7450 MB/s read, 6500 MB/s write
3D TLC NAND
1mm graphene composite heat sink
Pros
- TLC NAND at a budget price point
- Highest listed read speed at 2TB
- Graphene heat sink
- screws and screwdriver included
Cons
- Heat sink is not pre-installed
- 80-hour test count is lower than rivals
- Less known brand
This is the drive we would pick for a console-only buyer who wants TLC endurance without the DRAM premium. 3D TLC NAND holds up better under repeated writes than the QLC alternatives at similar cost, and the Maxio MAP1602 controller is a proven part.
Read is listed at up to 7450 MB/s, the joint highest figure in this guide, with write at 6500 MB/s. A 1mm graphene composite heat sink is included and claims roughly 10C of cooling on the chip.
The heat sink is not pre-installed, and that is the one task you have to do yourself. Some owners find the thermal pad sticker fiddly to remove, so read the instructions before you start.
The package also includes screws and a screwdriver, and the drive went through 80 hours of testing before shipping. Warranty is five years.
What you should know before you buy
Read the install steps. Attaching the heat sink is the difference between a two-minute job and a frustrating one, and the pad placement is where mistakes happen.
The stated 10C cooling improvement is a chip-level claim, not a console-level guarantee. The PS5 shroud still does most of the work.
Who should skip it
Anyone who wants a completely hands-off install should pick a drive with the heat sink already attached. Buyers who need mature brand support may prefer an established name.
If you need maximum capacity, 2TB is the limit here, and 4TB drives exist for a reason.
PS5, PS5 Slim and PS5 Pro Are Not the Same Slot
This is the single biggest source of returns and forum confusion, and it deserves more space than any spec sheet. The original PS5 has the deeper expansion bay. The PS5 Slim and PS5 Pro share a shallower one, and a drive with a tall finned heat sink can physically fail to seat even when every specification on the box says PS5 compatible.
Our rule from twelve installs: a bare drive, a drive with a low-profile heat spreader, or a drive with a heat sink designed for the PS5 bay. Anything advertised only for PCs is a gamble if you own a Slim or Pro. If you are still undecided on console accessories in general, our wireless PS5 headset guide covers another common upgrade path.
Double-sided boards are the second clearance issue. Where a single-sided drive populates memory on one face only, a double-sided board stacks chips on both sides and adds height. All twelve drives in this guide are M.2 2280 sticks, but check the physical height before ordering rather than after.
How to Install an M.2 SSD in Your PS5
The install is genuinely simple on the original console and slightly fiddly in the Slim and Pro because of the tighter bay. Allow twenty minutes, unpowered, with the console on a soft surface.
Power the console down fully and unplug the power cable from the back.
On the original PS5, remove the two panels and the central spine to expose the expansion bay. On Slim and Pro, remove the single rear panel and the two side plates.
Loosen the single retaining screw next to the M.2 slot and set it somewhere safe.
If your drive has a heat spreader that clips on, fit it now. It is much harder to reach afterwards.
Insert the M.2 drive at roughly a 30-degree angle, gold contacts into the slot first.
Push it flat and re-tighten the retaining screw over the notch at the end of the board.
Replace the panels, reconnect power, and boot the console.
Go to Settings, then Storage, then Expand Storage and select the new drive.
Format it as PS5 storage. The console erases the drive completely, so copy anything important off it first.
Once formatted, move games across from Settings, then Storage, then Games and Apps. Select the games, choose Move, and pick the M.2 drive as the destination. Moving is far faster than reinstalling, and it frees internal space you can keep clear for system updates.
How Much Storage Do You Actually Need?
Answer the question honestly and the capacity falls out on its own. Count how many games you actively play plus the two or three you want installed but unplayed. Multiply by roughly 100GB for a modern open-world title, more for the largest releases, and leave about 100GB of headroom on the drive.
At 1TB you are looking at a rotating library of about six to eight large games plus system files. That works, and it is the smallest size we would recommend over internal storage. At 2TB you roughly double that, which is the sweet spot for most owners installing one expansion drive.
At 4TB you can keep a serious back catalogue without deleting anything, which is why it appeals to owners of multiple large libraries. Beyond that, cost per terabyte becomes the deciding factor rather than capacity itself.
Buying Guide: What Actually Matters on a Console
Gen5 is wasted money here. A Gen5 drive negotiates at Gen4 x4 speeds in a PS5 and draws more power doing it. Nothing on the console’s current hardware architecture unlocks the extra bandwidth, so a Gen5 purchase buys a desktop upgrade, not a console one.
DRAM-less is fine. Drives like the one in this guide that use a host memory buffer instead of a DRAM cache are the majority of what gets recommended for consoles. The buffer covers mapping, and console writes arrive in large sequential blocks where the difference rarely appears. Buy DRAM for heavy sustained desktop writes, not for a games console.
TBW matters less than you think. A modern title is a few gigabytes of writes, not a few terabytes. Even the 600 TBW drive in this guide outlasts a console generation. Read the figure, but do not let a low number push you into a slower drive.
Firmware and management software matter more than the badge. Drives with a desktop tool such as Samsung Magician or the Biwin suite can be updated and checked before you install. A firmware update on a PC first is the cheapest insurance in this guide, particularly on models with early teething problems.
Brand barely matters for a console. Sony does not maintain a hard whitelist in the way some accessory brands do. Any drive meeting the requirements above is recognised on first boot. What matters is the warranty process if a drive fails, and how you feel about a refund.
What PS5 Owners Actually Report Back
Across the recommendation threads on r/playstation, the same three names keep coming up as the safe defaults: the Samsung 990 Pro, the WD_BLACK SN850X and the Seagate FireCuda 530. One commenter put it plainly, noting the 990 Pro is technically the fastest but the difference is not huge. That is the consensus view, and it matches what we measured.
The same threads are full of owners confirming a successful install, with a WD SN850X 2TB being a recurring example. The recurring questions are not about speed at all: they are about slot depth, heatsink fit, and whether an internal M.2 drive is worth it against a cheaper external USB drive.
On that last point, the honest answer is about library size. If you play a handful of titles, an external drive is the cheaper route. If you want twenty large games installed at once, internal expansion is the only option, because PS5 games must live on internal storage or an M.2 drive to run.
Frequently Asked Questions
Which NVMe is best for PS5?
The WD_BLACK SN850P 1TB is the safest choice because it is officially licensed for PlayStation 5, comes with a console-profiled heat sink and carries a five-year warranty. If you want maximum capacity instead, the Corsair MP600 PRO LPX 4TB gives you a large library with 4GB of DRAM cache for sustained writes.
Which NVMe SSDs are compatible with the PS5?
Any M.2 2280 PCIe 4.0 x4 NVMe drive with at least 1TB of capacity and roughly 5000 MB/s sequential read works. What matters beyond that is physical clearance. PS5 Slim and PS5 Pro owners should choose a bare drive, a low-profile heat spreader, or a heat sink designed for the console bay.
Is 4TB overkill for PS5?
Only if you play a small rotating library. Four terabytes holds roughly thirty to forty large games alongside system files, which suits owners who never want to delete anything again. If you play six to eight titles at a time, 2TB gives you the same freedom at a much lower cost per terabyte.
Is 2TB overkill for PS5?
For most owners, 2TB is the sweet spot rather than overkill. It holds about fifteen to twenty large games with headroom to spare, and the cost per terabyte is usually better than a 1TB drive. You would only need more if you plan to keep a large back catalogue installed permanently.
Is 1TB or 2TB better for my PS5?
If you play mostly digital purchases you want ready to launch, choose 2TB. If you mostly play a few games and delete the rest, a 1TB drive is enough. A 1TB drive also gives a better cost per terabyte in some cases, so check both before deciding which capacity suits your library.
Do PS5 SSDs need heatsinks?
A bare M.2 drive works fine because the console’s own shroud presses against it and moves air across the board. A low-profile heat sink adds margin during long sustained writes, and it is closer to necessary inside a PS5 Slim or PS5 Pro where the bay is tighter. Avoid tall finned heat sinks designed for desktops.
Can you use a Gen5 SSD in a PS5?
You can, but you gain nothing. A Gen5 drive negotiates at PCIe 4.0 x4 speeds in the PS5 and typically draws more power at the same time. Gen5 is worth buying for a modern PC with a compatible board, and it is wasted money as a console expansion drive.
Does it matter what SSD I get for PS5?
Within reason, no. Any M.2 2280 PCIe 4.0 drive that fits the slot and meets the capacity and speed baseline will run games normally, and Sony does not maintain a hard approved list. Choose on clearance, endurance, warranty support and price per terabyte rather than on brand name.
The Verdict
Our best NVMe SSDs for PS5 storage expansion shortlist in 2026 comes down to this: buy the WD_BLACK SN850P 1TB if you want the officially licensed, zero-guesswork option, and buy the Corsair MP600 PRO LPX 4TB if your library is the reason you are here. The Samsung 990 PRO 2TB is the fastest drive in the guide that still fits comfortably in a Slim or Pro bay.
Everything else on the list is a variation on that theme rather than a different recommendation. Check your console model for clearance before you order, pick a capacity that matches how many games you want ready to launch, and update the firmware from a PC first if the drive offers the tooling. Storage expansion is the upgrade that keeps paying off every time a new release lands.
