For most PS5 owners, a 2TB PCIe Gen4 M.2 NVMe drive with a PS5-sized heatsink already fitted is the safest upgrade, with the WD_BLACK SN850P, Samsung 990 Pro with heatsink and Crucial T500 with heatsink the names roundups mention most; budget buyers can look at the Lexar NM790 or fanxiang S880ER, and anyone who only wants to store older games can use a cheaper external USB drive. The details below cover what Sony requires, how to read a spec sheet, and which buyer each drive suits.

What Sony Requires From a PS5 Expansion SSD
Sony publishes compatibility conditions for the M.2 expansion slot, and review outlets repeat them consistently. The drive must be a PCIe Gen4 x4 M.2 NVMe SSD with a Key M connector. Supported capacities run from 250GB to 8TB, and supported lengths range from 2230 up to 22110. Sony recommends sequential read speeds of 5,500MB/s or faster, and it does not support M.2 SATA drives. The drive also needs effective heat dissipation, which in practice means a heatsink.
The size limits for the cooler are tight. Sources quoting Sony’s guidance describe a maximum assembly width of 25 mm, a maximum thickness of 11.25 mm, no more than 8 mm of height above the board and no more than 2.45 mm below it. That is why many drives are sold with a “PS5-ready” heatsink: a tall gaming-motherboard heatsink with fins can simply not fit the slot.
Some retailers’ guides call the heatsink optional but recommended, while others treat it as required. Since Sony’s own conditions mention heat dissipation, using one is the conservative choice. The console’s slot differs a little between the original model, the Slim and the Pro, so look at the maker’s compatibility notes for your exact console.
Storage Expansion SSDs at a Glance
| Drive | Best for | Key stated points | Limits |
|---|---|---|---|
| WD_BLACK SN850P | Buyers wanting a console-designed drive | Named by roundups as a best-for-PS5 pick; sold in heatsink versions for the console | Premium tier of PS5 drives |
| Samsung 990 Pro (with heatsink) | Performance-focused buyers | Listed by TechRadar and others; heatsink version needed for the slot | Buy the heatsink variant, not the bare drive without checking clearance |
| Samsung 980 Pro (with heatsink) | Buyers who find it at a good tier | Gen4 drive on TechRadar’s list | Previous generation of the Pro line |
| Crucial T500 (with heatsink) | Balanced mid-range choice | A recent roundup names the 2TB with heatsink as best balanced | Confirm the heatsink version |
| Lexar NM790 | Value seekers | The maker says it meets the PS5 requirements; a version with a PS5-clearance heatsink is sold | Needs a heatsink if sold bare |
| fanxiang S880ER | Budget buyers | Described as a value pick by Review Consensus | Less established brand |
| Corsair MP600 PRO LPX / Seagate FireCuda 530R | Alternatives with heatsink options | Listed by Asumetech among heatsink-ready picks | Compatibility depends on the exact SKU |
Specs such as speeds and endurance come from the makers; reviewers’ real-world game loading differences are usually small between decent Gen4 drives.
How Much Capacity Do You Need?
The console’s internal storage fills quickly with big modern titles. A common view in guides such as Stevivor’s is that a 2TB drive with a built-in heatsink is the upgrade to make for most owners. A 1TB drive is a lower-tier compromise that suits players who rotate a handful of games, and 4TB suits people who keep a huge library installed and do not want to delete anything.
- 1TB: Budget and mid-range tiers; holds a few large games plus smaller ones.
- 2TB: The sweet spot most roundups point to for libraries of ten or more big titles.
- 4TB and above: Premium tier; makes sense for large digital libraries.
Gen4 Versus Gen5 Drives
Some newer Gen5 drives work in the slot but run at Gen4 speeds, and they are not part of Sony’s listed requirements. They often run hotter and cost more for no extra benefit on the console, so reviewers generally steer buyers toward Gen4.
Heatsinks: Pre-Fitted or DIY
Pre-fitted heatsinks save effort and guarantee a clearance-friendly profile. Separate heatsinks can be cheaper, but you must check the measurements against Sony’s limits and apply the thermal pad correctly. If you are unsure, buy a drive sold as PS5-ready with the cooler attached.
Installation and Safety Notes
- Power the console down fully and unplug it before opening the cover.
- Touch a metal part of the chassis or use an anti-static strap before handling the drive.
- Follow Sony’s on-screen steps to format the drive and run its speed check on first use.
- Back up saves to cloud storage or USB first, since the console may need a software update when the drive is first used.
- Opening the console may affect warranty terms. Read the console maker’s terms, and if you are uncomfortable with the steps, ask a qualified technician.
Internal Versus External Storage
| Option | Can run PS5 games? | Best for |
|---|---|---|
| Internal M.2 SSD | Yes | Playing PS5 titles directly from expanded storage |
| External USB drive | PS4 titles only; PS5 games can be stored but need to be moved back to play | Archiving and older games |
Pick X If …
| If you want … | Pick |
|---|---|
| A console-focused, premium drive | WD_BLACK SN850P |
| High performance and brand reputation | Samsung 990 Pro with heatsink |
| A balanced mid-range 2TB | Crucial T500 with heatsink |
| A value option with a stated PS5 version | Lexar NM790 |
| The lowest tier that still meets the spec | fanxiang S880ER |
| Extra room for old games only | External USB SSD or hard drive |
Alternatives
- Corsair MP600 PRO LPX: A Gen4 drive aimed at the console and sold with a low-profile cooler.
- Seagate FireCuda 530R: Another heatsink-ready Gen4 option that appears in roundups.
- Portable SSDs: Good for moving PS4 titles or archiving PS5 games, but not for direct play of PS5 games.
Reading an SSD Spec Sheet
Spec sheets can look confusing, but only a handful of lines matter for a console. First, look for the interface: it should say PCIe Gen4 x4 and NVMe, and the connector should be M.2 Key M. Second, look at the stated sequential read speed; Sony’s recommendation is 5,500MB/s or faster, and many Gen4 drives list figures well above that. Third, look at the form factor, which is shown as a four- or five-digit number such as 2280. The first two digits are the width in millimetres and the remaining digits the length, so 2280 is 22 mm wide and 80 mm long. The slot supports lengths between 2230 and 22110.
Then look at endurance and warranty. Makers list endurance as terabytes written, and warranty periods are usually several years. A higher endurance figure and longer warranty tend to track with the premium tier. Console gaming is mostly reading data, so heavy write endurance is rarely the limiting factor, but a longer warranty gives extra reassurance.
DRAM Cache and Why It Matters Less Here
Some drives include a dedicated DRAM cache and others use host memory or no cache. For PC work with many small writes this can matter. For loading games on a console, reviewers generally find drives with and without DRAM load titles in similar times, so do not pay a premium for that line alone. Focus on heatsink fit, sustained speed and the maker’s compatibility notes.
Counterfeit and Mislabelled Drives
Because SSDs are small and easy to relabel, buy from reputable sellers and check the capacity in the console’s storage menu after installation. If a drive shows a capacity or speed far from its label, contact the seller and stop using it before saving important data.
After Installation
Once the drive is in, the console formats it and runs a speed test. If the drive fails the test, the usual causes are a loose seating, a drive that does not meet the speed requirement, or a heatsink that is pressing on the board. Power down, reseat and try again. Moving games between internal and expansion storage is done in the storage menu, and many players keep their most-played titles on whichever drive they find simplest to manage.
PC Gamers Reusing Drives
Players who also build gaming PCs sometimes wonder whether a spare Gen4 drive from a desktop can be moved into the console. If it meets the interface, length and speed conditions and fits with a suitable heatsink, it can work, though the console formats the drive and erases its contents. Back up anything on it first, and remember that a PC-style tall heatsink will not fit in the console slot.
Frequently Asked Questions
Do I need a heatsink on a PS5 SSD?
Sony’s conditions mention effective heat dissipation, and the safest course is to use one. Choose a heatsink that fits within the maker-stated size limits, or buy a drive sold with a PS5-ready cooler.
Can I use a SATA M.2 drive?
No. Sony does not support M.2 SATA drives; the slot requires a PCIe Gen4 x4 NVMe drive with a Key M connector.
Will a Gen5 SSD work?
Reviewers report that Gen5 drives generally run at Gen4 speeds, but they are outside Sony’s listed requirements. They also tend to cost more and run warmer, so most guides favor Gen4.
How big a drive should I buy?
Most guides lean toward 2TB for general use. A 1TB drive works if you rotate games, and 4TB suits large libraries.
Can I play PS5 games from an external drive?
Not directly. External USB storage can hold PS5 games, but they need to be copied back to internal storage before you play. External drives can run PS4 titles.
Is installing an SSD difficult?
It involves removing the console cover and seating the drive in the slot, which many owners manage with the maker’s instructions. If you are not comfortable, consult a qualified technician, and read the terms about opening the console.
