View on AmazonOur Take
The WD Black SN850X 2TB is a high-end PCIe Gen 4 NVMe SSD aimed squarely at PC gamers and power users who want top-tier storage performance. It sits near the summit of the consumer SSD market, competing directly with Samsung's 990 Pro and Seagate's FireCuda 530. The included heatsink variant makes it particularly well-suited to PS5 expansion.
Key Features
PCIe Gen 4 x4 interface with NVMe 1.4 protocol
Sequential read speeds up to 7,300 MB/s and sequential writes up to 6,600 MB/s
M.2 2280 form factor with low-profile metal heatsink included

Our Verdict
The SN850X 2TB is the right choice for serious PC gamers, content creators, and PS5 owners who want the fastest consumer Gen 4 storage available without compromise. If you're on a tighter budget or running an older Gen 3 system, a mid-range drive will serve you equally well day-to-day for considerably less money.
