  • Speed may vary due to host hardware, software, usage, and storage capacity.
  • The workload used to rate DWPD may be different from your actual workload, which may vary due to host hardware, software, usage, and storage capacity.
  • Terabytes Written (TBW) expresses the endurance under the highest capacity.
  • Some motherboards only provide PCIe x2 connections for the M.2 slot, creating a bottleneck on even the fastest drives.

System Requirement

Operating System
  • Microsoft Windows 7 or later
  • Linux Kernel 2.6.31 or later
  • Please make sure that your computer has a M.2 slot.
  • Systems for use with the PCIe M.2 SSD must have an M.2 connector with only an M key. B-key connectors are not compatible. Improper insertion may lead to damage. Please click here for more information.
