Manufacturer description
The WD Blue SN5100 2TB NVMe SSD (model WDS200T5B0E) is a PCIe Gen 4.0 upgrade for desktops and laptops that have an M.2 2280 slot. Sequential reads reach up to 7,100 MB/s. The manufacturer rates that as 30% faster than the previous WD Blue generation, a claim that applies to the 1TB and 2TB models. The 2TB capacity uses Sandisk 3D CBA NAND. That leaves room for a large game library, raw photo and video projects, or local AI models and datasets, all on one slim M.2 card without extra cables. Sandisk nCache 4.0 is built to speed up long copy jobs, so moving large files or whole project folders…
