Buy the WD_BLACK 2TB SN850P.

Same speed class, real PS5 certification, and it costs a lot less than the Samsung.

What was compared

Samsung SSD 990 PRO 2TB, PCIe 4.0 M.2 2280, Up to 7,450 MB/s | NVMe Internal Solid State H... — $387.80
WD_BLACK 2TB SN850P NVMe M.2 SSD Officially Licensed Storage Expansion for PS5 Consoles, u... — $224.99

1. Same tier of drive, $160 cheaper
The SN850P and 990 Pro sit in the same PCIe 4.0 performance class, but the WD is over $160 less at $224.99 versus $387.80. Paying that much extra for a drive that does the same job is not smart spending, it is spec-sheet worship.
2. Actually built and licensed for PS5
The SN850P is officially licensed for PlayStation 5, tested and approved by Sony for zero compatibility headaches. The 990 Pro is a general-purpose PC drive, fine in a console but never certified for it, which matters if you are buying for a PS5 specifically.
3. Fewer horror stories about dying drives
Research turned up owner reports of Samsung 990 Pro units losing capacity fast even under light use, a real red flag for a drive meant to hold your whole library. The WD shows no such pattern in the same research, just consistent praise for running cool and reliable.
4. Backed by real endurance numbers
WD rates this drive at up to 1,200 TBW with a 5-year warranty behind it, giving you a documented lifespan promise. That is the kind of number that actually predicts how long a drive survives, not just how fast it reads a file.
5. Yes, Samsung reads faster on paper. Ignore it.
The 990 Pro claims 7,450MB/s versus the SN850P's 7,300MB/s, a gap that sounds impressive and does nothing for you. Reviewers testing both note load time differences of tenths of a second, invisible in any real game or workload. That 150MB/s is a marketing number, not a reason to spend $160 more.
