Note
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.
