Western Digital BLACK SN7100 4TB M.2 2280 PCIe Gen 4.0 7000MB/s SSD

The Western Digital WDS400T4X0E-00CJA0 is a 4TB M.2 2280 solid state drive that connects through a PCIe Gen 4.0 NVMe interface. It can deliver up to 7000 MB/s sequential read speed and up to 6700 MB/s sequential write speed, making game levels, large creative projects, and data-heavy applications load with very little waiting.

The drive uses TLC 3D NAND and offers up to 900K random read and 1350K random write IOPS. A DRAM-less architecture lowers power draw, so gaming laptops and handheld devices can stay cooler and run longer on battery. With an endurance rating of 2,400 TBW and a five-year limited warranty, it is prepared for frequent recording, editing, or development work where data is written and erased day after day.

For PC gamers, the SN7100 trims level load times and leaves room for massive libraries. Content creators gain a fast workspace for 4K footage, high-resolution photos, or complex audio sessions. Developers and researchers can rely on quick builds and data transfers when compiling code or training models. Any system that supports an M.2 2280 slot and PCIe Gen 4.0 bandwidth can tap into the storage headroom and speed this drive provides.
