The WD PC SN720 is an OEM M.2 2280 NVMe drive built on Western Digital's 64-layer 3D TLC NAND with an in-house controller and no DRAM cache. It is a PCIe 3.0 x4 part, so it tops out around 3,400 MB/s sequential read and roughly 2,800 MB/s write on the 256GB model, with random performance that trails DRAM-equipped drives like the Samsung 970 EVO. It suits laptop upgrades, small-form-factor builds and secondary storage where capacity and low power draw matter more than sustained heavy writes. Buyers should note the 256GB tier is the slowest in the line and its endurance rating is modest.
