Flash memory prices keep climbing across the board, so a discount on licensed console storage is well worth paying attention to. The WD_BLACK 2TB expansion card, which has the official Sony seal of approval and works flawlessly with the PlayStation 5, is marked down from $350 to $300 at Amazon. That’s doing some serious upstream swimming against a torrent of skyrocketing memory prices, and there’s no telling how long it will last.
This is WD’s answer to the storage problem every PS5 owner eventually hits. Modern game titles routinely weigh in between 50 and 100GB, and Sony’s internal SSD fills up faster than most people expect. Third-party drives technically work in the PS5’s M.2 expansion slot, but this one is officially licensed — meaning Western Digital and Sony tested and certified it together, with no compatibility concerns and no asterisks. You install it, the PS5 recognizes it, and you play directly from the drive without transferring anything first.
No Slowdowns
The WD_BLACK expansion card’s read speeds top out at 7,300MB/s over PCIe Gen 4, which is fast enough that load times from the expansion drive are effectively indistinguishable from the console’s internal storage. That matters more than the raw number — slower drives installed in the PS5 slot can create a noticeable gap on titles optimized for the console’s storage architecture. The WD_BLACK doesn’t have that problem. WD also designed a heatsink specifically for the PS5’s M.2 bay to prevent thermal throttling during long sessions.
Sony estimates that you can fit roughly 200 games at an average of 36GB per title on the 8TB PlayStation 5, which scales down to somewhere around 50 more games at a realistic modern install size on the 2TB expansion card— plenty of breathing room before you’re making hard decisions about what to delete. The drive handles everything from PS5 titles to the full PS4 back catalog without any performance penalty or separate management.
Perfect Timing
Flash storage — particularly licensed, console-specific variants — rarely gets meaningful discounts now that supply is tight and demand from AI infrastructure is consuming silicon in enormous quantities. The WD_BLACK is that rare deal subject because of its seamless fit with the PS5, its ease of installation in the vacant M.2 slot, and its remarkable ability to run Sony’s native software and maintain speed.
With this Amazon deal offering 2TB of certified, heatsink-equipped PS5 storage for just $300, the WD_BLACK expansion card is a straightforward choice. No compatibility research required, no thermal workarounds, no performance gap — it extends your console’s storage as if the capacity was always there.
