SanDisk X400 256GB SATA SSD

The SanDisk X400 256GB drive is a 2.5-inch internal solid state drive using SATA III interface and TLC memory. It suits users upgrading laptops or desktops that need reliable solid-state storage for everyday workloads. The 7mm height fits standard drive bays in many systems.

Fits 2.5-inch SATA drive bays

This 2.5-inch 7mm drive connects through a standard SATA III port and requires a matching power connector inside the chassis. It replaces mechanical hard drives directly without extra brackets in most laptops and desktops. The single-sided M.2 variant exists but this unit uses the cased 2.5-inch form factor.

Sustained performance with error correction

Sequential speeds reach up to 540 MBps read and 520 MBps write while random performance hits 93,500 IOPS read and 75,000 IOPS write. nCache 2.0 technology optimises read and write operations during extended use. DataGuard client and LDPC error correction protect data integrity across the 0°C to 70°C operating range. MTTF is rated up to 1.75M hours with endurance up to 320 TBW.
