78 out of 100 medium confidence 18 reviews

The Kingston NV3 SSD generally receives positive feedback for its ease of installation, speed, and reliability in everyday use.

  • Reliable in daily use
  • Good value at normal price
  • Works well for OS storage
Cons
  • Price increased significantly
  • No DRAM (uses HMB)
