Western Digital WDS100T4X0E WD_BLACK SN7100 1TB NVMe SSD

The WD_BLACK SN7100 1TB NVMe SSD is built for gamers and power users who demand fast storage without sacrificing battery life. Powered by SanDisk's next-generation TLC 3D NAND and a PCIe Gen4 interface, it achieves sequential read speeds up to 7,250 MB/s and write speeds up to 6,900 MB/s — representing up to a 35% performance improvement over its predecessor. That translates to shorter game load times, faster level transitions, and snappier file transfers for content creators working with large media assets. The standard M.2 2280 form factor ensures broad compatibility across desktops, laptops, and handheld gaming devices.

Where the SN7100 particularly stands out is power efficiency. Western Digital engineered this generation to consume up to 100% less power than the previous model, a meaningful improvement for anyone gaming on a laptop or handheld where every watt matters. The downloadable WD_BLACK Dashboard (Windows only) gives you visibility into drive health, temperature, and remaining lifespan, along with tools to optimize performance. Available in capacities up to 2TB, the SN7100 offers a strong balance of speed, efficiency, and storage space for a Gen4 drive at its price point.
