Flagship Gen4 Speed Without Draining Your Battery

Gaming laptops and handheld PCs need fast storage, but high-power SSDs shorten battery life and add heat in cramped chassis. Many efficient drives, however, trade away speed.

The SN7100 combines both. Its WD Polaris 3 controller and BiCS8 TLC NAND deliver up to 7,250MB/s while averaging about 2.4W, making it one of the most efficient high-end Gen4 drives for portable and compact gaming systems.

Top-Tier Gen4 Performance

With up to 7,250MB/s reads, 6,900MB/s writes and up to 1.4M random write IOPS, the SN7100 shortens game loads, installs and file transfers. It supports PS5 speed requirements with a heatsink.

Efficient and Durable

Low average and idle power extend battery life and keep temperatures down. The 2TB model is rated for 1,200 TBW and 1.75 million hours MTBF.
