The WD Black SN770 is a PCIe 4.0 NVMe SSD in the M.2 2280 form factor, built on Western Digital's own controller and 112-layer TLC NAND. It has no DRAM cache, relying on host memory buffer, yet reaches sequential reads up to 5,150 MB/s on the 1TB model. It suits gamers and everyday upgraders who want fast Gen 4 speed without paying for a premium drive. Against DRAM-equipped rivals like the Samsung 980 Pro or WD's own SN850X, it trails in sustained heavy writes but runs cooler and is easier to fit in laptops and PS5 consoles.
