What's inside
The WD_BLACK 1TB SN850P is an officially licensed PS5 storage expansion drive: a Gen4 NVMe SSD in the M.2 2280 form factor that ships with a pre-installed heatsink shaped to fit Sony’s console slot, rated for reads up to 7,300 MB/s. Western Digital designed it as the no-fuss, drop-in answer for players who have run out of room on their PlayStation 5.
It is aimed squarely at PS5 owners who want a guaranteed-compatible upgrade without researching heatsink dimensions or thermal clearances, and who value plug-and-play simplicity over squeezing out every last dollar. PC builders can use it too, but its licensing, heatsink profile, and marketing are built around the console audience first.

Design & Build
The standout feature is the low-profile aluminum heatsink, engineered to sit flush under the PS5’s expansion cover with no clearance worries. The drive is a single-sided M.2 2280 board, and the whole package is designed so you unbox it, drop it in, screw down the cover, and format it in the console’s menu. Build quality is typical WD_BLACK: tidy, understated, and backed by a five-year limited warranty. There is no RGB or flourish here, just a component meant to disappear into the console.
Performance
Inside a PS5 the SN850P easily clears Sony’s speed requirement, so games install, copy, and load from it just as they would from the console’s internal drive. In practice you will not notice a difference in load times between the built-in storage and this expansion, which is exactly the point. The integrated heatsink keeps it within a safe thermal window during long sessions and large installs.
On a PC it behaves like a competent Gen4 drive, with strong sequential speeds and solid random performance, though it is not class-leading and the console-oriented heatsink can be redundant on a motherboard that already has one. Its value proposition is tied to the PS5 context; as a general desktop drive there are faster and cheaper options.
Pros & Cons
- Officially licensed for PS5 with a perfectly fitting pre-installed heatsink
- Genuine plug-and-play install with no compatibility guesswork
- Fast enough to match internal PS5 storage in load times
- Five-year warranty and dependable WD_BLACK reliability
- Carries a licensing premium over unbranded Gen4 drives of similar spec
- The 1TB capacity fills quickly with today’s large console titles
- Less compelling as a pure PC drive, where the heatsink is redundant
Alternatives to Consider
If you want more headroom, the 2TB Western Digital SN850 for PS5 doubles capacity for larger libraries. Budget-focused buyers who are comfortable adding their own heatsink can save with the WD_Black SN7100 1TB, a fast Gen4 drive without the console licensing. And PC owners on a newer platform who want future-proof speed should look at the WD_Black SN8100, a Gen5 drive that far outpaces the SN850P in raw throughput.
Frequently Asked Questions
Does the SN850P work in a PS5 out of the box?
Yes. It is officially licensed and ships with a fitted heatsink, so you install it, replace the cover, and format it through the PS5’s storage menu with no extra parts or research required.
Is it fast enough for the PS5’s requirements?
Comfortably. Its rated read speed exceeds Sony’s minimum, so games run from it exactly as they would from the internal SSD, with no perceptible difference in load times.
Can I use this drive in my gaming PC instead?
You can, and it performs like a solid Gen4 SSD. However, the built-in heatsink may conflict with a motherboard’s own M.2 cooler, and cheaper or faster options exist for pure PC use, so its best value is inside a PS5.
Is 1TB enough for a PS5?
It adds meaningful room, but modern console games are large, so a 1TB expansion can fill up faster than you expect. Heavy gamers who install many big titles should consider a 2TB option.
Verdict
The WD_BLACK SN850P is the easiest, most worry-free way to expand a PlayStation 5. You pay a small premium for the official licensing and tailor-made heatsink, but in return you get a genuine drop-in upgrade that matches internal speeds and just works. Buy it for the console convenience; if you are strictly building a PC, a standard Gen4 or Gen5 drive will serve you better for the money.
