The speed printed on the box is the least reliable number in any listing for the best 4TB SSD for PS5. The Lexar NM790 is the clearest case: its own spec table gives a media speed of 6,500 megabits per second, while a bullet three lines above promises 6,500MB/s. That is an eight-fold gap between two fields in a single advert. The fanxiang S660 repeats the pattern — a bullet says up to 5,000MB/s, the Data Transfer Rate field says 5,000 megabits per second. Even the WD_BLACK SN850P at the top of this list carries a Data Transfer Rate of 7,300 megabits per second beside a Read Speed of 7,300 megabytes per second.

We ranked ten of the best 4TB SSD for PS5 on Amazon on three things you can check without a benchmark rig: whether a drive's own spec table agrees with its own marketing bullets, whether a heatsink is included rather than sold separately, and what each terabyte costs at the listed price. Review volume was weighted, but a 4.8 from 435 buyers was not treated as equal to a 4.7 from 11,325. Capacity claims were taken as given. Speed claims were not.

## The ranking

### 1. WD_BLACK SN850P 4TB PS5 SSD with Heatsink

- Price: £413.99 | Amazon rating: 4.7 from 11,325 ratings
- Full review: https://www.ranked10.co.uk/tech/best-4tb-ssd-for-ps5/wd-black-sn850p-4tb-ps5
- Buy on Amazon: https://www.amazon.co.uk/dp/B0C48HN4Z9?tag=ranked10-21

Top of this list of the best 4TB SSD for PS5 because it is the only drive here with official PlayStation licensing, a console-shaped heatsink and 11,325 ratings behind it.

It sits first because it is the only drive here that Sony has officially tested and licensed, and because its 4.7 average comes from 11,325 ratings — the second-largest base in the round-up, behind only the SN850X. At £413.99 it also undercuts the SN850X 4TB by £86.00, despite carrying the same 7,300MB/s read claim, and it is the most affordable drive among the best 4TB SSD for PS5 options that come with a heatsink already fitted.

The engineering is straightforward: a PCIe Gen4 x4 NVMe drive in M.2 2280, with a heatsink that carries the PlayStation logo and is shaped for the console's own bay, so installation needs no modification. WD_BLACK quotes 7,300MB/s read and 6,600MB/s write for the 2TB and 4TB models. In practice the console's Gen4 interface is the ceiling, not the drive. Worth noting: the spec table's Data Transfer Rate field reads 7,300 megabits per second, while the Read Speed field a few lines away says 7,300 megabytes per second.

Skip it if price per terabyte is your only metric — the Acer GM7000 is £411.98 and the fanxiang S660 is £399.99. Skip it too if the highest buyer average matters more than the official badge, because the Corsair MP600 PRO LPX scores 4.8 from 10,543 buyers. And if you want the extras a PC owner gets, such as dashboard software and encryption, this drive is not where they live.

Pros: Officially tested and licensed for the PlayStation 5, the only drive here that is; 4.7 average from 11,325 ratings, with 85% of them five-star; Heatsink designed for the PS5 M.2 slot and included, not sold separately; £413.99 — £86.00 less than the SN850X 4TB, which claims the same 7,300MB/s read; Rated 7,300MB/s read and 6,600MB/s write on the 2TB and 4TB models
Cons: Its spec table lists a Data Transfer Rate of 7,300 megabits per second next to a 7,300 megabytes-per-second read speed — two units, one advert; Not the cheapest 4TB here: the fanxiang S660 is £399.99 and the Acer GM7000 £411.98; The Corsair MP600 PRO LPX scores 4.8 from 10,543 buyers, a slightly higher average; No dashboard software or encryption features for PC users

### 2. Corsair MP600 PRO LPX 4TB PS5 SSD

- Price: £415.01 | Amazon rating: 4.8 from 10,543 ratings
- Full review: https://www.ranked10.co.uk/tech/best-4tb-ssd-for-ps5/corsair-mp600-pro-lpx-4tb
- Buy on Amazon: https://www.amazon.co.uk/dp/B09Q2N9QGQ?tag=ranked10-21

Second because it beats the top pick on the one figure that is hard to argue with — 4.8 from 10,543 ratings — for £1.02 more.

It takes second place on buyer verdicts: 4.8 from 10,543 ratings, with 86% of them five-star. On paper it is the best 4TB M.2 SSD for PlayStation 5 here if you weight reviews above official licensing, and Corsair states it exceeds all Sony PS5 M.2 performance requirements. The quoted speeds are 7,100MB/s sequential read and 6,800MB/s sequential write.

A low-profile aluminium heatspreader is pre-fitted, so there is no extra part to buy and no clearance question to solve. The interface is PCIe Gen4 x4 NVMe 1.4, and the drive weighs 40g. The heatspreader's job is to hold sustained speed during a long install rather than to hit a peak number once — in theory the difference is minor, and in practice it is the number you notice when copying a 100GB game.

The catch is written into the listing itself. One bullet warns that international products have separate terms, are sold from abroad and may differ in fit, labelling and instructions. If a UK warranty process matters to you, that sentence is worth reading twice. Note also that its Data Transfer Rate field reads 7,100 megabits per second while the read speed is given in megabytes per second.

Pros: 4.8 average from 10,543 ratings, the highest in this round-up, with 86% five-star; Quoted 7,100MB/s sequential read and 6,800MB/s sequential write; Low-profile aluminium heatspreader pre-installed, no separate purchase needed; £415.01 — £1.02 above the top pick and £84.98 below the SN850X; 40g and compact, an easy fit in the PS5 expansion bay
Cons: Its Data Transfer Rate field reads 7,100 megabits per second while the read speed is listed in megabytes per second; Its own bullet warns it is an international product sold from abroad, with separate terms and possibly different labelling; Lower claimed read speed than four drives below it, which quote 7,400MB/s or 7,450MB/s; No PlayStation licensing, unlike the SN850P

### 3. WD_BLACK SN850X 4TB NVMe SSD

- Price: £499.99 | Amazon rating: 4.8 from 15,665 ratings
- Full review: https://www.ranked10.co.uk/tech/best-4tb-ssd-for-ps5/wd-black-sn850x-4tb
- Buy on Amazon: https://www.amazon.co.uk/dp/B0D9WTKV1B?tag=ranked10-21

Third on volume and price: 4.8 from 15,665 ratings, the largest base here, but at £499.99 it costs £86.00 more than the licensed SN850P.

The SN850X has 15,665 ratings at 4.8 — the largest evidence base in this round-up — and 88% of them are five-star, the highest share among the three biggest-selling drives. The problem is the £499.99 price, which is £86.00 above the officially licensed SN850P for the same 7,300MB/s read claim. As a 4TB PCIe Gen4 SSD for PS5 it works; as a value proposition it does not lead.

It is built on Western Digital TLC 3D NAND with capacities listed up to 8TB, and the model name carries TCG Opal Encryption 2.0. The WD_BLACK Dashboard adds health monitoring and Game Mode 2.0 — however, the bullets state plainly that Dashboard is Windows only, so a PS5 owner gets none of those extras. Meanwhile the heatsink is described as an optional version, so confirm which variant you are ordering.

Two listing contradictions are worth checking before you buy. Its compatible-devices field lists PS5, while the console compatibility field names the Sony PlayStation 4. One of those fields is wrong and the advert does not say which. If you want the drive Sony licensed and a console-shaped heatsink in the box, buy the SN850P instead and keep the £86.

Pros: 4.8 from 15,665 ratings, the largest review base here, with 88% five-star; Rated 7,300MB/s read and 6,600MB/s write across 1TB to 4TB models; Built on Western Digital TLC 3D NAND, with capacities listed up to 8TB; TCG Opal Encryption 2.0 named in the model designation; Predictive Loading, Overhead Balancing and Adaptive Thermal Management
Cons: £499.99, the joint-highest price here and £86.00 above the licensed SN850P; Its console compatibility field names the Sony PlayStation 4 while the devices field lists PS5; The heatsink is described in its own bullets as an optional version, so check the variant; Dashboard and Game Mode 2.0 are Windows only, so a PS5 owner cannot use them

### 4. Lexar NM790 4TB NVMe SSD with Heatsink

- Price: £499.99 | Amazon rating: 4.7 from 1,528 ratings
- Full review: https://www.ranked10.co.uk/tech/best-4tb-ssd-for-ps5/lexar-nm790-4tb-heatsink
- Buy on Amazon: https://www.amazon.co.uk/dp/B0CJY6W8WT?tag=ranked10-21

Fourth: the 7,400MB/s read claim ties the highest figure here, but its own spec table gives the write speed as 6,500 megabits per second against a bullet saying 6,500MB/s.

As a 4TB SSD with heatsink for PS5 it reads well on paper: 7,400MB/s read, 6,500MB/s write, PCIe Gen4, M.2 2280, with PlayStation 5 named in the console compatibility field. It ties the Acer GM7000 for the highest claimed read speed in this round-up. However, the advert's own spec table lists the media speed as 6,500 megabits per second, against a bullet three lines above that says 6,500MB/s — a factor of eight, inside one listing.

The design is DRAM-less and depends on Host Memory Buffer 3.0, which borrows the host system's memory for caching instead. Lexar claims up to 40% lower power consumption than DRAM-cached Gen4 drives, and the metal heatsink is fitted in the box. For a PS5 install that is the detail that matters: sustained writes during a 100GB game copy, not the peak read figure on the front.

That said, £499.99 is a lot for a DRAM-less drive, and 1,528 ratings is roughly a tenth of the feedback behind the SN850P. If you want the best 4TB SSD for PS5 by price, this is not it. If you want the highest claimed read speed and can accept a thinner review record, this and the Acer GM7000 are the two candidates.

Pros: 7,400MB/s claimed read, level with the Acer GM7000 for the highest figure here; Heatsink and metal enclosure supplied with the drive; HMB 3.0 instead of DRAM, with Lexar claiming up to 40% lower power draw than DRAM-cached Gen4 drives; PlayStation 5 named in its console compatibility field; Standard M.2 2280 fit in a 4TB capacity
Cons: Its media speed field reads 6,500 megabits per second while a bullet says 6,500MB/s — an eight-fold gap in one advert; £499.99 for a DRAM-less design, the joint-highest price in this list; 1,528 ratings against 11,325 for the top pick, a much thinner evidence base; Lower claimed write speed, 6,500MB/s, than the SN850P at 6,600MB/s and the Corsair at 6,800MB/s

### 5. Acer Predator GM7000 4TB PCIe Gen4 M.2 SSD

- Price: £411.98 | Amazon rating: 4.7 from 3,143 ratings
- Full review: https://www.ranked10.co.uk/tech/best-4tb-ssd-for-ps5/acer-predator-gm7000-4tb
- Buy on Amazon: https://www.amazon.co.uk/dp/B0BNTFVVGD?tag=ranked10-21

Fifth and the cheapest drive here that claims 7,400MB/s read, at £411.98, with a DRAM cache and a 5-year warranty but no metal heatsink.

At £411.98 it is the cheapest drive in this list that claims 7,400MB/s read — £2.01 below the licensed pick at the top and £88.01 below the SN850X. It is a PS5 4TB storage expansion on paper, with the PS5 named in both the compatible devices and the console compatibility fields. It also carries an independent DRAM cache, which the Lexar NM790 and the Fikwot FX991 do not.

Cooling is where it differs from everything above it. Instead of a finned heatsink, Acer fits a graphene cooling pad and claims it dissipates heat well enough to prevent throttling under sustained load. Random performance is quoted at 1,300K read IOPS and 1,100K write IOPS. The box contents list Acronis True Image software rather than mounting hardware, which means you supply the screw yourself.

Do not buy it expecting a plug-and-play console fit: two of the drives above ship with metal heatsinks and this one does not. Its 3,143 ratings are respectable but around a third of the Corsair's. Either way, at £411.98 it is the price leader among the fast drives, and the 5-year product assurance is stated in its own bullets.

Pros: £411.98, the cheapest drive here claiming 7,400MB/s read; Independent DRAM cache, unlike the Lexar NM790 and the Fikwot FX991; 5-year product assurance stated in its own bullets; 4.7 from 3,143 ratings, with 85% five-star; Quoted 1,300K random read IOPS and 1,100K random write IOPS
Cons: Cooling is a graphene pad rather than the finned heatsink the PS5 bay is built around; Box contents list Acronis True Image software, with no mounting screws included; 3,143 ratings against 11,325 for the SN850P; Its product features list a heatsink while the bullets describe only a graphene cooling pad

### 6. BIWIN Black Opal NV7400 4TB PCIe Gen4 SSD

- Price: £429.99 | Amazon rating: 4.5 from 899 ratings
- Full review: https://www.ranked10.co.uk/tech/best-4tb-ssd-for-ps5/biwin-black-opal-nv7400-4tb
- Buy on Amazon: https://www.amazon.co.uk/dp/B0DM1R7KJ1?tag=ranked10-21

Sixth: 7,450MB/s is the highest claimed read speed in this round-up, but 4.5 from 899 buyers is the lowest average in the top six.

Sixth, on the strength of the highest claimed read figure here: 7,450MB/s, with 6,500MB/s write and up to 1,000K random IOPS. As a 4TB NVMe SSD for PS5 it is well specified and priced at £429.99, mid-pack in this list. Crucially, though, this is also where the buyer evidence starts to thin: 4.5 from 899 ratings is the lowest average of the six drives above the £450 mark.

The design uses HMB rather than an onboard DRAM cache, plus a composite power management IC and a graphite heat sink over the NAND. Biwin also bundles its Biwin Intelligence backup software free with the drive. The box contents list an SSD, a screw and a manual, so unlike the Acer you do get the mounting hardware.

Buy it if you want the biggest read number and the software bundle; skip it if you want a metal heatsink or a long track record. Seven buyers out of 899 gave it one star, roughly one in 128. Even so, at 899 ratings this is a drive you are taking more on trust than on evidence, which means its headline 7,450MB/s should carry less weight than 15,665 ratings for the SN850X.

Pros: 7,450MB/s claimed read, the highest figure in this round-up; 6,500MB/s claimed write and up to 1,000K random IOPS; £429.99 mid-pack, and a mounting screw is included in the box; Free Biwin Intelligence backup software bundled; PMIC power management plus HMB and Smart Cache
Cons: 4.5 rating, the lowest average of any drive in the top six; 899 ratings, a small sample next to the 10,000-plus behind the top three; Graphite heat sink rather than the metal heatsinks on the SN850P and Corsair; HMB instead of an onboard DRAM cache, so it borrows the host system's memory

### 7. Fikwot FX991 4TB PCIe Gen4 NVMe SSD

- Price: £429.99 | Amazon rating: 4.4 from 2,758 ratings
- Full review: https://www.ranked10.co.uk/tech/best-4tb-ssd-for-ps5/fikwot-fx991-4tb-ssd
- Buy on Amazon: https://www.amazon.co.uk/dp/B0D4YDX9LQ?tag=ranked10-21

Seventh on a 4.4 average and 9 one-star reviews from 2,758 — and on a 300MB/s gap between the 7,300MB/s in its bullets and the 7,000MB/s in its own spec table.

The FX991 earns its place in a best 4TB SSD for PS5 list with endurance and price rather than speed. It quotes 2,400TBW — the highest figure stated by any drive here — for £429.99, with a 5-year EU spare-part availability window. It also has 2,758 ratings at 4.4.

It uses HMB and a smart SLC cache, plus adaptive temperature and power management that Fikwot says adjusts heat and power draw automatically. The bundled heatsink is graphite rather than metal, and the box contents confirm that. Efficiency is quoted at up to 40% better performance-per-watt than the previous Gen4 model, which matters far more in a laptop than in a console that is plugged into the mains.

By contrast with the drives above it, the advert's own numbers disagree. The bullets promise 7,300MB/s read and 6,300MB/s write; the spec table gives 7,000MB/s read and a media speed of 6,200MB/s — 300MB/s and 100MB/s lower, in the same listing. Add the lowest average rating here at 4.4 with 9 one-star reviews, and this is a budget endurance pick, not a speed pick.

Pros: 2,400TBW endurance rating, the highest stated in this round-up; £429.99 for 4TB with HMB and SLC cache; 5-year EU spare-part availability stated in its own specs; Claims up to 40% better performance-per-watt than its previous Gen4 SSD; 2,758 ratings at 4.4, a reasonable sample for the price
Cons: Bullets say 7,300MB/s read while the spec table says 7,000MB/s — a 300MB/s gap in one advert; 4.4 average is the lowest in this list, with 9 one-star reviews; Graphite heatsink rather than a metal one; No DRAM cache; it relies on the host's memory through HMB

### 8. fanxiang S660 4TB PS5 SSD with Heatsink

- Price: £399.99 | Amazon rating: 4.6 from 3,715 ratings
- Full review: https://www.ranked10.co.uk/tech/best-4tb-ssd-for-ps5/fanxiang-s660-4tb
- Buy on Amazon: https://www.amazon.co.uk/dp/B0C6DMCJNF?tag=ranked10-21

Eighth and the cheapest 4TB drive here at £399.99 — but also the slowest on claimed speed, with 4,800MB/s in its own spec table against 5,000MB/s in the bullet.

Eighth, and the cheapest 4TB drive in this round-up at £399.99 — £11.99 below the Acer and £100.00 below the SN850X. It is not the best 4TB PS5 SSD on speed, and its own advert says so twice over: the bullet promises up to 5,000MB/s read, while the Read Speed field gives 4,800MB/s. The Data Transfer Rate field shuffles the units again, reading 5,000 megabits per second.

It is a PCIe 4.0 drive in M.2 2280 with a grey heatsink that the bullets say may require manual installation, so budget ten minutes and a screwdriver. fanxiang claims 88 hours of testing and states a 5-year warranty. Capacities run from 500GB to 4TB, so the 4TB version is not a one-off production run.

Skip it if you move large games around often and want the fastest installs; at 5,000MB/s it sits at the bottom of this list on claimed speed, level with the Ediloca EN760. It is a reasonable choice for parking a large library of PlayStation titles you only play occasionally. Worth noting as well: the spec table lists a Hard Disk Rotational Speed of 4,500, a field with no meaning on a solid state drive.

Pros: £399.99, the lowest price in this round-up for 4TB; 4.6 from 3,715 ratings, with 82% five-star; 5-year warranty stated in its own bullets, with 88 hours of testing claimed; Heatsink included, though the listing says it may need fitting by hand; Capacities from 500GB to 4TB, so the 4TB model is one of several
Cons: Slowest claimed drive here: 5,000MB/s read in the bullets, 4,800MB/s in the spec table; Spec table lists a Hard Disk Rotational Speed of 4,500, a field that means nothing on an SSD; Data Transfer Rate field reads 5,000 megabits per second while the bullet says 5,000MB/s; Heatsink may require manual installation

### 9. Ediloca EN760 4TB PCIe Gen4 SSD with Heatsink

- Price: £459.99 | Amazon rating: 4.6 from 840 ratings
- Full review: https://www.ranked10.co.uk/tech/best-4tb-ssd-for-ps5/ediloca-en760-4tb-ps5
- Buy on Amazon: https://www.amazon.co.uk/dp/B0CJRW8GSS?tag=ranked10-21

Ninth: £459.99 for a 5,000MB/s drive with an aluminium heatsink, mounting screws and a 2,800TBW rating.

Ninth: £459.99 for a 4TB PCIe Gen4 SSD for PS5 that claims the same 5,000MB/s read and 4,500MB/s write as the fanxiang above it, which costs £60.00 less. What that premium buys is an aluminium heatsink, mounting screws and a screwdriver in the box, plus a stated 2,800TBW endurance rating. The spec table and the bullets agree on the 5,000MB/s figure, which is not true of every drive here.

The NAND is 3D QLC with a dynamic SLC cache, so short bursts run at full speed while long sustained writes fall back to QLC rates. The M.2 2280 form factor is listed as compatible with PS5, Windows PCs, Mac and Linux. Ediloca states a 5-year limited service with lifetime technical assistance.

With 840 ratings and 77% five-star, this has one of the thinnest feedback records in the list, and 4 buyers gave it one star. It is not the best 4TB SSD for PS5 for sustained writes once the SLC cache fills up. Buy it for the bundled heatsink and tools; look at the £411.98 Acer if you want more speed for less money. The form factor field, incidentally, reads 2280 Inches, which is not a measurement.

Pros: Aluminium heatsink fitted, with screwdriver and mounting screws in the box; 2,800TBW endurance rating stated in its own bullets; 5,000MB/s read and 4,500MB/s write, with the spec table agreeing with the bullets; 4.6 from 840 ratings; M.2 2280 form factor listed for PS5, Windows, Mac and Linux
Cons: £459.99, £60.00 more than the fanxiang that claims the same 5,000MB/s; 3D QLC NAND with dynamic SLC cache, so sustained write speed drops once the cache fills; 840 ratings and 77% five-star, among the lowest five-star shares here; Its spec table lists a form factor of 2280 Inches, which is not a real measurement

### 10. Lexar EQ790 4TB NVMe SSD with Heatsink

- Price: £469.99 | Amazon rating: 4.6 from 435 ratings
- Full review: https://www.ranked10.co.uk/tech/best-4tb-ssd-for-ps5/lexar-eq790-4tb-ssd
- Buy on Amazon: https://www.amazon.co.uk/dp/B0FRSN5Y56?tag=ranked10-21

Tenth: the smallest review base here at 435 ratings, and the second-highest price at £469.99 for a 7,000/5,000MB/s drive.

Tenth, and the smallest sample in the round-up: 435 ratings at 4.6. At £469.99 it is also the second-most expensive 4TB drive here, £56.00 above the licensed SN850P, for a claimed 7,000MB/s read and 5,000MB/s write. Nothing in the advert disqualifies it. Equally, nothing in it argues for this drive over the five sitting above it.

It uses the PCIe 4.0 interface with NVMe, HMB and SLC cache, and Lexar claims power management that adjusts consumption to load rather than running flat out. A heatsink is included. The listed weight is 100g, heavier than the other drives here and consistent with a fitted metal heatsink rather than a graphite film.

It is a sensible drive in an unsensible position in this list. At £469.99 it is not the best 4TB SSD for PS5 on value when the £411.98 Acer and the £413.99 licensed WD_BLACK both sit below it. That said, if you specifically want Lexar's 5-year limited warranty, this is the cheaper of the two Lexar drives here — the NM790 is £499.99.

Pros: 7,000MB/s read and 5,000MB/s write quoted, with the two spec fields in agreement; Heatsink included, and the listed 100g weight suggests metal rather than film; HMB and SLC cache, with power management tied to load; 4.6 from 435 ratings, with 82% five-star; 5-year limited manufacturer warranty stated in its own bullets
Cons: £469.99 is the second-highest price here, £56.00 above the SN850P; 435 ratings, the smallest review base in this round-up; Lower claimed read speed than the 7,400MB/s and 7,450MB/s drives above it; Beaten on price and on claimed speed by the £411.98 Acer Predator GM7000

## Verdict

For most people, the WD_BLACK SN850P at £413.99 is the safest of the best 4TB SSD for PS5 drives here: it is the only one with official PlayStation licensing, it ships with a heatsink shaped for the console's M.2 slot, and its 4.7 average rests on 11,325 ratings rather than a few hundred. If you want the Gen4 ceiling for £1 more, the Corsair MP600 PRO LPX at £415.01 carries the higher average, 4.8 from 10,543 buyers, with a low-profile aluminium heatspreader instead of a PlayStation-branded one. On a tighter budget, the fanxiang S660 at £399.99 is the cheapest 4TB drive in this round-up — however, it is also at the bottom of the list on claimed speed, and its spec table gives 4,800MB/s read against a bullet promising 5,000MB/s. Either way, the best 4TB SSD for PS5 for your console is the one whose two sets of numbers agree. In short, buy the capacity and the heatsink, then treat every speed figure as advertising.
