The WD_Black SN7100 is a PCIe Gen4 M.2 2280 internal SSD rated up to 7,000 MB/s read and 6,700 MB/s write. It is a DRAM-less drive built on WD's own controller and BiCS TLC NAND, aimed at gamers and builders who want fast Gen4 storage without paying for a flagship. Against Gen4 rivals like the Samsung 990 Pro and Crucial T500 it gives up some peak speed and sustained write performance, but it runs cooler and draws less power, which suits laptops and PS5 use. Owners rate it as a solid value pick for everyday speed.
