WD Red SN700-NVMe SSDs has capacities to 4TB for NAS and up to 5,100 TBW

The WD Red SN700 is the first of a series of PCIe 3.0 x4 SSDs designed for use in network-attached storage (NAS) systems from Western Digital. The M.2 SSDs are available in capacities ranging from 250GB to 500GB, as well as 1TB, 2TB, and 4TB. As stated by the manufacturer, they are appropriate for long-term use.

The WD Red SN700 SSDs are equipped with TLC NAND memory and a controller that has not been revealed. According to WD, sequential read and write rates can reach 3430MB/s and 3100MB/s, respectively. Serial write speed is limited to 1600MB/s with the 250GB version due to the size of the disk. No dram buffer is known to be present on the ssds, which means that they all use the SLC cache as their primary cache. The specifications appear to be nearly identical to those of the 2019 WD Black SN750 SSDs, however the idle consumption has been tuned down and the stated endurance has been increased. As a result, SSDs should be acceptable for long-term use in network-attached storage systems.
