The X400 adds a 1TB M.2 option that SanDisk claims is the first single-sided 1TB M.2 drive. The X400 also adds LDPC ECC to the mix, which probably helped SanDisk increase the warranty period to 5 years.

The SanDisk X400 was sampling to OEMs as of late last year and is now available to OEMs and system integrators in volume.

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.

NCACHE TM 2.0 AND DATAGUARDTM:

ADVANCED TECHNOLOGIES FOR A BETTER EXPERIENCE
SanDisk technologies combine nCache 2.0, DataGuard and LDPC error correction into the X400 SSD for a superior experience and endurance levels up to 320 TBW (terabytes written), our highest ever for a client drive. 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.

DESIGNED WITH SECURITY IN MIND
The X400 SSD includes self-encrypting drive (SED) capabilities to quickly and easily protect sensitive documents from theft or disclosure. We also support TCG Opal 2.0 for interoperability with a wide spectrum of security software platform.
