Best 2TB SSD for PS5 in 2026: 10 Ranked Against Sony’s Own Rules

This is the only drive in the ranking that Sony has officially tested and licensed for the PlayStation 5, and in a category where the main risk is buying something that does not fit, that removes the entire question. The heatsink is designed specifically for the PS5's M.2 slot, carries the PlayStation logo, and is dimensioned to close under the expansion cover without forcing.

Performance is at the top end regardless: 7,300MB/s read and 6,600MB/s write on the 2TB model, comfortably above Sony's 5,500MB/s recommendation, so games load as fast as anything else here. WD offers the same drive up to 8TB, which the listing frames as room for around 200 games.

The 11,321 ratings behind its 4.7 average make it the second most reviewed drive on this list, and every one of those buyers was almost certainly putting it in a console — unlike the general-purpose drives here, where the feedback is mostly from PC builders. At £309.99 it is the most expensive drive in the ranking, £44.99 more than the Crucial below it. What you are paying for is the licence and the guarantee that nothing about the fit is your problem. If that certainty is worth £45 to you, buy this and stop reading.

If the WD's official licence feels like a premium you would rather not pay, this is the drive to buy instead. Crucial sells it explicitly as a PS5 SSD, the heatsink version is the one listed here, and the product description states plainly that it is easy to install in a PlayStation 5. There is no ambiguity to resolve and no separate heatsink to source.

At 7,100MB/s it is 200MB/s slower on paper than the WD, a difference you will never perceive in a load screen, and 1,600MB/s above Sony's minimum. Crucial quotes nearly 20% faster bootups and gameplay against the previous generation, and backs the drive with a 5-year limited warranty.

Crucial is Micron's consumer brand, which means the flash inside is made by the same company that designs it — a meaningful thing in a category where several brands here simply buy NAND on the open market. With 1,621 ratings it has less feedback than the WD or the Samsung, but enough to be a known quantity. At £265.00 it saves you £44.99 against the licensed drive while answering the only question that actually matters in this category. For most people this is the sensible buy.

At £249.99 this is the lowest-priced drive in the ranking that ships with a genuine integrated heatsink rather than a thermal pad or sticker. For a PS5 that is the specification that matters, and it is why this sits above several faster and cheaper drives.

Speeds are 7,000MB/s read and 5,000MB/s write. That read figure is the lowest on this list, though still 1,500MB/s clear of Sony's minimum, and the write speed is the one place it trails the pricier options meaningfully. Lexar highlights the heatsink's role directly: it prevents thermal throttling during long sessions, which is exactly the failure mode Sony's heatsink requirement exists to avoid. The drive is also quoted as using up to 40% less power than DRAM-cache Gen4 rivals, helped by HMB 3.0 and dynamic SLC cache instead of a dedicated DRAM chip.

Two caveats. With 394 ratings it has the second-smallest sample here, so long-term feedback is thin. And it is worth looking at number nine on this list before ordering: the identical EQ790 without the heatsink is £229.99. That £20 gap is the entire difference between a drive that drops straight into a PS5 and one that does not — which makes this the better buy of the pair, not the worse value.

On raw merit this drive is superb. Its 4.8 average across 2,456 ratings is the highest score on the list, it reads at 7,200MB/s and writes at 6,200MB/s — second only to the Samsung and the WD on write — and at £228.99 it is the second cheapest drive here. It uses PCIe 4.0 with the NVMe 2.0 protocol, Host Memory Buffer and SLC cache, and Acer names PS5 storage expansion directly in the description.

The reason it is not higher is thermal management. Acer describes an intelligent thermal control system and a graphene thermal pad, which is a thin conductive layer bonded to the drive, not a finned heatsink with mass to absorb heat. In a PC with case airflow that is usually adequate. Inside the sealed M.2 bay of a PS5, where Sony requires a cooling structure precisely because there is no airflow, it is a genuinely open question — and Acer does not claim it satisfies Sony's requirement.

One more thing worth knowing: this listing states the form factor as 2.5 inches, which is simply wrong for an M.2 2280 drive and suggests the specification fields were not filled in carefully. If you already own a compatible PS5 heatsink, this is arguably the best-value drive on the page. If you do not, budget for one or buy the Crucial.

The NV7400 matches the Samsung 990 PRO for the fastest read speed in this ranking at 7,450MB/s, pairs it with 6,500MB/s write and up to 1,000K IOPS random performance, and costs £55 less than the Samsung. It is labelled PS5 Ready and uses 3D TLC NAND with a composite power management IC that BIWIN says improves efficiency and extends drive life.

Its thermal solution is a 0.5mm graphene aluminium heat sink. That is more substantial than a bare thermal pad and it is bonded rather than loose, but at half a millimetre it is a long way from the finned heatsinks on the WD and Crucial. It will keep the drive cooler than nothing at all; whether it satisfies Sony's requirement in a sealed bay is not something BIWIN commits to in writing.

BIWIN is an unfamiliar name to most UK buyers, though the company has manufactured storage components for other brands for decades — and notably, it is the same company behind the management software on the Acer Predator drive at number four. With 859 ratings the sample is moderate. Free Biwin Intelligence backup software is included. Good drive, genuine speed, but the heatsink question keeps it below the three unambiguous picks.

Let us be clear about what this drive is: on specification it is the best on this page. 7,450MB/s read and 6,900MB/s write are the fastest figures here, endurance is rated at up to 1,200TB written, and its 12,875 ratings are the most of any drive in the ranking. In a PC, the 990 PRO is a benchmark product.

The problem is that this particular listing is the version without a heatsink. Samsung sells a separate 990 PRO with Heatsink model; this is not it. The description mentions a heat spreader and dynamic thermal guard, which is the thin thermal label and firmware throttling protection that every modern drive has — not a cooling structure of the sort Sony requires. Tellingly, the listing's own compatible devices field reads desktop, laptop and PC. PS5 is not among them.

That does not make it unusable in a console. It makes it an incomplete purchase: you would need to buy a compatible PS5 heatsink separately, typically £10 to £20, fit it yourself, and accept that the combined height must stay under 11.25mm. If you are comfortable doing that, you get the fastest drive here. If you want to open a box and drop it in, this is not the listing to order, and at £300.99 it is £35.99 more than the Crucial that comes ready to go.

At £219.99 this is the cheapest drive in the ranking, £9 below the Acer and £90 below the WD, and it does not achieve that by dropping the two things that matter. It ships with a heatsink, and it has a dedicated DRAM cache rather than relying on Host Memory Buffer — which is what several pricier drives here, including the Lexar and the Acer, do without.

DRAM cache matters for sustained performance. Drives using HMB borrow system memory to hold the mapping table; a drive with its own DRAM does not, which generally means more consistent behaviour under heavy sustained writes. Speeds are 7,300MB/s read and 5,400MB/s write, and fanxiang backs it with 5 years of after-sales support.

Two things hold it back. Its 4.2 average across 1,495 ratings is the lowest on this list, and it is the only drive here below 4.5 — with a sample large enough that the score is a real signal rather than noise. And the listing's compatible devices field names only desktop and laptop, even though the product name and description both reference PS5. It is not a bad drive, and the DRAM cache is a genuine advantage at the price, but the rating gap to the Acer at £9 more is hard to ignore.

On paper the X7400 does everything right. It is PCIe Gen4x4, reads at 7,350MB/s, ships with a heatsink, lists PS5 among its compatible devices, and includes the screws and screwdriver you need for installation — a small courtesy that the premium brands often skip. A 5-year limited warranty backs it.

The difficulty is price positioning. At £289.99 it costs £24.99 more than the Crucial P310 and only £20 less than the officially licensed WD_BLACK, while SIX is a brand almost no UK buyer will have heard of and its 647 ratings are among the smaller samples here. In a category where the entire purchase decision turns on trusting that a component fits and lasts inside a sealed console bay, spending flagship money on an unknown quantity is a hard case to make.

If it were £180 the calculation would be different and the included installation kit would look like a genuine bonus. At £289.99 the Crucial is cheaper and better established, the WD is £20 more and carries Sony's own licence, and the Acer is £61 cheaper with a higher rating. It is a competent drive priced as though it were a famous one.

This is the clearest illustration on the page of the trap this category sets. It is the same Lexar EQ790 that sits at number three: identical PCIe Gen4 controller, identical 7,000MB/s read and 5,000MB/s write, identical HMB and SLC cache technologies, identical 5-year support. The only difference is that this version does not include the heatsink, and it costs £20 less.

For a laptop or a desktop with case airflow, that makes this the better buy of the pair and a perfectly sensible drive — it has more ratings than the heatsink version too, 1,639 against 394, so it is the more proven listing. Lexar lists PlayStation 5 among its compatible devices.

But for a PS5 specifically, buying this means buying an aftermarket heatsink separately, checking that the combined height clears 11.25mm, and fitting it yourself. A PS5-compatible heatsink typically costs £10 to £20, which erases most or all of the £20 saving and adds a step where you can get it wrong. Unless you already have a spare heatsink in a drawer, spend the extra £20 and take number three instead. Same drive, one less thing to solve.
