High Performance and High Reliability Meet High Style

Built with SanDisk's sixth-generation TLC flash, the X400 SSD offers quick responsiveness, high reliability and low power for a seamless experience for thin and ultramobile notebooks. It's the ideal storage solution for heavy workloads such as photo and video editing, multitasking or office productivity.

Thin Is In

With a 1.5mm single-sided form factor (M.2 2280 module), the X400 SSD is the first single-sided 1TB SSD in the industry, giving it the performance and capacities ideal for ultrathin designs. The X400 SSD is also available in 2.5" 7mm-height to be a true drop in replacement for mechanical HDDs.

SanDisk nCache 2.0 is a set of advanced algorithms that analyze workloads to improve fast burst performance and sustained sequential write speeds while minimizing energy consumption and controller overhead. The X400 SSD is backed by a 5-year warranty.
