What's inside
The WD_BLACK SN850P 1TB is Western Digital’s officially licensed PlayStation 5 storage expansion drive, shipping with a pre-installed heatsink and rated for reads up to 7,300 MB/s. It is designed to drop straight into the PS5’s M.2 expansion bay with no guesswork about compatibility or cooling.
This drive is for PS5 owners who have run out of internal space and want a plug-and-play solution that is guaranteed to meet Sony’s requirements. Because it is licensed and pre-cooled, it removes the two things console users most often get wrong with aftermarket SSDs: speed validation and heatsink fitment. It works in a PC too, but its whole identity is built around the console.

Design & Build
The SN850P uses a low-profile heatsink sized specifically to clear the PS5’s expansion slot cover, so there is no filing, measuring, or worrying about the lid closing. It is a single M.2 2280 drive with WD’s controller and 3D NAND under a clean, understated aluminum spreader. The heatsink is effective without being tall, and the whole package feels purpose-built rather than adapted. A five-year warranty backs it.
Performance
On the PS5, the SN850P comfortably exceeds Sony’s speed floor, so games installed to it load essentially as fast as titles on the internal drive, and moving large games back and forth is quick. In everyday console use you will not perceive a difference from the built-in storage, which is exactly the point of a licensed expansion drive.
The pre-installed heatsink keeps temperatures in check during long install sessions and extended play, avoiding the throttling that can affect bare drives in the enclosed PS5 bay. Dropped into a PC it performs like a solid PCIe 4.0 drive, though there its heatsink and PS5-tuned firmware are less of a selling point.
Pros & Cons
- Officially licensed for PS5 with guaranteed compatibility
- Pre-installed heatsink sized to fit the console with no fuss
- Fast load times that match the internal SSD in practice
- Five-year warranty and trusted WD_BLACK reliability
- Priced above comparable bare PCIe 4.0 drives you cool yourself

- 1TB fills quickly for large modern game libraries
Alternatives to Consider
If you would rather add your own cooling and save money, the Western Digital SN850 for PS5 covers similar ground. PC builders chasing raw speed should instead look at the WD_Black SN8100 2TB, a PCIe 5.0 drive rated near 14,900 MB/s, while laptop and handheld users may prefer the compact, efficient WD_Black SN7100 1TB. And if you simply need cheap bulk console storage for older-gen titles, the external WD_BLACK D10 Game Drive is a budget-friendly companion.
Frequently Asked Questions
Does the SN850P need any setup on PS5?
Almost none. Install it in the expansion bay, close the cover, and the PS5 formats it in seconds. The pre-installed heatsink means no assembly is required.
Is it faster than the PS5’s internal SSD?
In practice they feel identical for gaming. The SN850P meets Sony’s requirement, so load times match the internal drive rather than beating it noticeably.
Can I use it in my PC instead?
Yes, it works as a standard PCIe 4.0 M.2 drive in a PC. Just note that its licensing and heatsink are optimized for the PS5, so a PC-focused buyer has cheaper equivalents.
Is 1TB enough for a PS5?
It roughly doubles usable space, which helps, but a few large modern games can fill it. Heavy players who install many AAA titles may want a 2TB drive.
Verdict
The WD_BLACK SN850P 1TB is the low-stress way to expand a PlayStation 5: licensed, pre-cooled, and fast enough that it disappears into the console experience. You pay a small premium for that convenience, and 1TB fills up fast, but for PS5 owners who just want storage that works without research, it is one of the safest picks available.
