X400 SATA M.2 2280 256GB

The SanDisk X400 is a 256GB internal solid-state drive built in the single-sided M.2 2280 form factor. It connects through a SATA III interface and uses TLC memory components. The drive is designed for enterprise workloads and operates between 0°C and 70°C.

Enterprise upgrade or SATA-only slot

This SSD suits systems that need a 256GB enterprise-class drive in an M.2 2280 package and have a SATA-based M.2 slot. It is not appropriate for platforms that require a PCIe-attached drive or for users seeking higher capacities than 256GB.

SATA III interface decides compatibility

The single specification that determines fit is the SATA III interface; the drive will only function in M.2 slots wired for SATA signalling. Verify the host slot supports SATA before purchase.

Questions sur cet article

Will this M.2 2280 drive fit in a laptop that only supports SATA M.2 SSDs?

Yes, the drive uses the SATA interface and the M.2 2280 form factor, so it fits slots wired for SATA M.2 devices.

What do the sequential speeds of 540 MBps read and 520 MBps write mean for daily use?

Those speeds are the practical ceiling of the SATA interface, giving fast boot times and quick loading of large files.

Is the 256 GB capacity enough for an operating system plus core applications?

256 GB comfortably holds Windows or Linux with everyday programs, leaving space for active project files.
