What's inside
The WD_BLACK SN850P 1TB is Western Digital’s officially licensed PS5 storage expansion, a PCIe Gen 4 NVMe drive that ships with a pre-installed heatsink and slots straight into the PlayStation 5’s expansion bay. Rated for up to 7,300 MB/s reads, it is essentially the console-ready, plug-and-play version of WD’s well-regarded SN850 platform, tuned and certified specifically for Sony’s requirements.
It is made for PS5 owners who want the simplest possible way to add fast, game-ready storage without researching heatsinks and compatibility. Because it is officially licensed and comes with the correct heatsink already fitted, it removes the guesswork that comes with buying a bare drive. PC builders and anyone chasing the highest possible speeds have better-value or faster options, but for a console upgrade the appeal is convenience.

Design & Build
The defining feature is the low-profile heatsink pre-installed to meet the PS5’s thermal and clearance requirements, so there is no separate part to buy or attach and no worry about fit under the console’s cover. The M.2 2280 drive itself is built on WD’s proven SN850 hardware, and the whole package carries a five-year warranty. The trade-off is that you are paying a licensing and convenience premium over a comparable bare drive plus a third-party heatsink.
Performance
Inside a PS5 the SN850P does exactly what it should: games install and load quickly, and it comfortably exceeds Sony’s speed requirement, so there is no practical difference in the console experience versus other qualifying drives. The included heatsink keeps it in check during the sustained writes of large game installs, which is precisely where an unsuitable drive would struggle.
The nuance is that its raw performance is standard PCIe 4.0, so on paper it is outrun by newer Gen 5 drives and even some faster Gen 4 parts. That matters little on PS5, where the console caps the benefit, but it does mean the SN850P is not the drive to buy if you also want it to shine as a high-speed PC boot drive. You are paying for certified simplicity, not record-setting numbers.
Pros & Cons
- Officially licensed for PS5 with a pre-installed heatsink
- True plug-and-play install with no compatibility guesswork
- Comfortably exceeds the PS5’s speed requirement for fast loads
- Proven SN850 hardware with a five-year warranty
- Convenience and licensing premium over a bare drive plus heatsink
- Standard PCIe 4.0 speeds are outpaced by newer drives
- Less compelling if you also want a fast PC boot drive
Alternatives to Consider
Buyers comfortable adding their own cooling can save with the Western Digital SN850 for PS5, which uses the same platform, or step to more capacity with the 2TB version. For a faster, more flexible drive that also excels in a PC, the WD_Black SN7100 offers strong Gen 4 speeds, while the PCIe 5.0 WD_Black SN8100 is the choice if outright throughput matters more than console-certified convenience.
Frequently Asked Questions
Do I need to buy a separate heatsink for the SN850P?
No. The heatsink is pre-installed and sized for the PS5’s expansion bay, which is the main reason to choose this drive over a bare SSD.
Is it fast enough for the PS5?
Yes. It comfortably exceeds Sony’s minimum speed requirement, so games load quickly and the console experience is indistinguishable from other qualifying drives.
Can I use it in a PC too?
You can, but it is standard PCIe 4.0 and its pre-fitted PS5 heatsink may not suit every motherboard, so it is not the ideal choice for a dedicated PC build.
Is it worth the premium over a bare SN850?
If you value a certified, no-hassle install, yes. If you are comfortable fitting your own heatsink, the bare SN850 delivers the same performance for less.
Verdict
The WD_BLACK SN850P 1TB is the easy-button PS5 upgrade: officially licensed, heatsink included, and fast enough that the console never becomes the bottleneck. You pay a premium for that certainty, and its plain PCIe 4.0 speeds mean it is not the drive for a speed-obsessed PC build. But for the many PS5 owners who just want to expand storage and get back to playing, its plug-and-play simplicity is worth the money.
