Western Digital has introduced a new WD Black SN750 SE CONSUBLIC CONCERS series in M.2 form factor with PCIe 4.0 interface support. It includes models for 250 and 500 GB, as well as 1 TB. The new series is designed to become more affordable alternative to WD Black SN850 NVME-drives flagship.

It should be reminded that the Western Digital range has an original WD_BLACK SN750 series with PCIe 3.0 interface support. According to the manufacturer, the new series has a 30% reduced level of energy consumption compared to previous models. But it was not possible to achieve this without compromise.
