WD Red SN700 NVMe 4TB NAS SSD

This SanDisk WDS400T1R0C-68BDK0 is a 4TB internal solid-state drive built for network-attached storage. It uses the M.2 2280 form factor and connects through a PCI-Express 3.0 x4 interface running the NVMe protocol.

Suits multi-user NAS caching and virtualization

Small-to-medium business environments with collaborative editing, database workloads or virtualization benefit from the high random IOPS. Desktop PCs or laptops without an M.2 slot supporting PCIe 3.0 x4 should consider a SATA drive instead.

Deciding specification is the 5100 TBW endurance

Rated at 5100 TBW and 1750000 hours MTTF, the drive is engineered for sustained write-heavy caching. If your workload exceeds this endurance figure, a higher-capacity or enterprise-class model is required.
