Review
The WD Black SN850P is the no-fuss way to expand PlayStation 5 storage. It's officially licensed for PlayStation, ships with a factory heatsink preinstalled, and clears Sony's 5,500 MB/s requirement comfortably at 7,300 MB/s.
That licensed badge matters: it means the drive has been validated for PS5, removing the guesswork around compatibility and thermals. Pop it into the expansion bay and the console recognizes it immediately.
You pay a premium over a bare drive plus an aftermarket heatsink, but the convenience and guaranteed fit are worth it for most console owners. The 4TB option essentially doubles or triples your playable library.
