The best PS5 internal SSD upgrade for most people is the WD_BLACK SN850P 2TB because its PS5-focused heatsink removes a compatibility job from the installation. A PS5 M.2 upgrade is not simply a race for the largest headline speed: the drive must be an M.2 2280 NVMe model, fit below the console cover with suitable cooling, and leave enough capacity for the games you actually keep installed.

How we compared these PS5 storage upgrades
We compared the documented capacity, interface, form factor, sequential specifications, cooling hardware and PS5 installation implications of three live US listings. All three are 2TB M.2 2280 PCIe 4.0 NVMe drives, so each offers much more room than the base console for modern games and patches. Their important difference is not capacity. It is whether the SSD already has a low-profile heatsink intended for the PS5 bay.
Sony's M.2 bay requires a compatible physical size as well as a PCIe 4.0 NVMe drive. A 2TB drive is a sensible middle ground for a library that includes several very large games, but it does not make every model interchangeable. Check the console's current expansion requirements, the exact drive dimensions and the supplied heatsink before purchase. Do not stack a second heatsink on an SSD that already has one.
WD_BLACK SN850P 2TB: best overall
WD_BLACK SN850P 2TB PS5 SSD
The WD_BLACK SN850P 2TB is the straightforward choice for a console-first upgrade. It is officially licensed for PlayStation 5, uses the M.2 2280 PCIe Gen4 NVMe format, and arrives with a purpose-built heatsink rather than asking the buyer to source thermal hardware separately. WD specifies up to 7,300 MB/s sequential reads and up to 6,600 MB/s writes for this 2TB model, giving it ample headroom over the common minimum guidance for PS5 expansion. Choose it if you value a clear, ready-to-install package and want 2TB without researching an extra heatsink. Its limitation is value flexibility: the PS5 licensing and integrated cooling are useful conveniences, but shoppers who already own a compatible cooler may find a more general drive a better fit for their budget.
Pros
- Officially licensed PS5 storage expansion with an integrated low-profile heatsink
- 2TB M.2 2280 PCIe Gen4 capacity for a substantial installed game library
- Documented up to 7,300 MB/s reads and 6,600 MB/s writes for the 2TB version
Cons
- Integrated cooler reduces the benefit if you already own a suitable PS5 heatsink
- PS5-specific positioning can cost more than a similarly specified general-purpose SSD
WD_BLACK SN850X 2TB with Heatsink: best value
WD_BLACK SN850X 2TB with Heatsink
The SN850X 2TB with Heatsink targets the buyer who wants high-end Gen4 specifications without paying specifically for console branding. This version is an M.2 2280 PCIe Gen4 NVMe SSD and includes WD_BLACK's factory heatsink, which is the key distinction from the bare SN850X variants. WD lists up to 7,300 MB/s reads and up to 6,600 MB/s writes for the 2TB drive, while its 2TB capacity makes it practical for a broad rotation of PS5 titles. It earns the value badge because it combines a ready-fitted heatsink with strong documented throughput. The limitation is that it is not the officially licensed SN850P package, so confirm the physical fit and follow Sony's installation guidance rather than assuming every pre-fitted PC heatsink is interchangeable.
Pros
- Factory heatsink avoids buying and mounting a separate thermal solution
- 2TB SN850X specification lists up to 7,300 MB/s read and 6,600 MB/s write speeds
- M.2 2280 Gen4 NVMe format matches the common PS5 expansion drive layout
Cons
- Not the PS5-licensed SN850P model, so fit confirmation remains important
- Heatsink version is less adaptable for a desktop that uses its own motherboard M.2 cover
Samsung 990 PRO 2TB: best for tuned setups
Samsung 990 PRO 2TB
Samsung's 990 PRO 2TB is a compelling performance-first pick for someone comfortable completing the cooling step themselves. The listed drive is a bare M.2 2280 PCIe 4.0 NVMe model with 2TB capacity, and Samsung rates this version for up to 7,450 MB/s sequential reads and up to 6,900 MB/s sequential writes. Samsung also supports firmware and health management through its Magician software when the drive is connected to a compatible computer. It is a good choice when you already have a correctly sized PS5 heatsink or are deliberately selecting one. That condition is also its meaningful drawback: this ASIN is not the heatsink edition, so it is not ready for the PS5 bay on its own. Add a compatible low-profile heatsink and verify clearance before installing it.
Pros
- Up to 7,450 MB/s read and 6,900 MB/s write specifications on the 2TB model
- Samsung Magician support provides a route for firmware and drive-health management
- Bare M.2 2280 design lets experienced buyers choose their own PS5-compatible heatsink
Cons
- This listing lacks a heatsink, so it needs additional cooling hardware for a PS5 installation
- Firmware management requires access to a compatible computer rather than the console alone
Capacity, cooling and installation decisions
Start with capacity rather than synthetic speed headlines. A 1TB upgrade can be enough for a focused library, but 2TB gives more room for large current games, updates and captured media before storage housekeeping becomes routine. All three picks here are 2TB, so the choice comes down to the installation experience. The SN850P is the simplest console-specific package. The SN850X with Heatsink is the alternative for buyers who want similar capacity and cooling without the official license. The 990 PRO is for a more deliberate build where the heatsink has been chosen separately.
Before opening the console, update its system software and read Sony's current M.2 SSD instructions. Power it down fully, use the appropriate screwdriver, avoid touching the connector contacts and retain the spacer in the position for an 2280 drive. After installation, the PS5 formats the new drive. Keep the console cover and expansion-bay cover in place after checking that the cooler does not interfere with either one.
Frequently asked questions
Does a PS5 SSD need a heatsink?
For an internal M.2 expansion, use a compatible cooling solution. The SN850P and the SN850X selected here include heatsinks. The Samsung 990 PRO in this comparison does not, so it needs a separate low-profile heatsink that meets the console's physical-clearance requirements. Never assume a tall desktop heatsink will fit under the PS5 cover.
Is 2TB enough for a PS5 game library?
For many players, 2TB is a practical long-term capacity because it leaves room for multiple large games alongside updates and downloadable content. It is not an unlimited library, especially if you keep several very large titles installed. Review your installed games and captures before deciding whether 2TB fits your habits or a higher-capacity model is worth considering.
Can I install the Samsung 990 PRO without a heatsink?
No. The B0BHJJ9Y77 listing is the bare 990 PRO, not Samsung's heatsink version. It may be suitable for PS5 storage only after a properly sized compatible heatsink is fitted. If you want the simpler route, choose a model that already includes a low-profile heatsink and still check its dimensions against Sony's current guidance.
