Western Digital BLACK SN850X 2TB PCIe 4.0 x4 NVMe M.2 2280

92 out of 100 medium confidence 13 reviews

The WD_BLACK SN850X 2TB is highly praised for its blazing-fast performance, making boot times and game loads nearly instant.

Pros

  • Near-instant boot and game loads
  • Runs cool with heatsink
  • Easy installation
  • Good for gaming and professional use
Cons
  • Runs hot without heatsink
  • Pricey, especially after recent increases
