Western Digital launches WD Red SN700 NVMe SSD: TLC NAND up to 4TB, 3,400 MB/s Transfer Rates

Western Digital today announced the launch of its budget TLC NVMe SSD, the SN700 (Red). The solid drive has an M.2 2280 connector and is aimed at NAS storage, as indicated by the Red branding. In terms of specifications, we’re looking at TLC NAND cells with storage capacities ranging from 250GB to 4TB. The SN700 has sequential read speeds of up to 3,400 MB/s and writes of up to 3,100 MB/s. 

The WD Red SN700 uses the PCIe 3.0 x4 interface, supporting the NVMe 1.3 protocol. The 1TB variant can perform random reads/writes of up to 500,000 IOPs, with the sequential write being reduced to 3,000 MB/s. It has a rated lifecycle of 2,000 TBW and meets the 24×7 hour usage associated with NAS storage. All the SN700 series solid-state hard drives come with a 5-year warranty.

The prices and ratings of the various SKUs are as follows:

  • SN700 4TB: 5100 TBW: US$650.
  • SN700 2TB: 2500 TBW: US$290.
  • SN700 1TB: 2000 TBW: US$145.
  • SN700 500GB: 1000 TBW: US$80.
  • SN700 250GB: 500 TBW: US$65.
