The SanDisk® X400 SSD is SanDisk’s upper-tier SATA client SSD, driving SATA SAS PCIe mainstream adoption in computing platforms for both corporate customers and end-consumers. It is designed with SanDisk’s nCache™ 2.0 technology to provide greater reliability and high-grade endurance for longevity and is backed by a five-year warranty.

Additionally, X400 can be successfully used in entry-level enterprise servers, typically for read-intensive and boot/logging applications. TCG OPAL 2.0 support means interoperability with leading industry security ISVs applications.

For products built around high capacities and thin form factors
From ultrathin consumer notebooks to corporate platforms, the X400 SSDs range of form factors and capacities deliver a variety of design and integration options for manufacturers and systems builders. With a 1.5mm single-sided form factor (M.2 2280 module), X400 SSD’s performance and capacities make it ideal for ultrathin designs. Additionally, the X400 SSD is available in 2.5” 7mm-height as a true drop inreplacement for mechanical HDDs. Both form factors are available in 128GB, 256GB, 512GB and 1TB capacities.

Responsiveness, reliability, and low power for the way consumers work
Built using SanDisk’s 2nd generation TLC flash node, the X400 SSD offers quick responsiveness, high reliability and low power for a seamless and productive user experience.

nCache™ 2.0 technology means better performance for professionals and enthusiasts
The X400 features nCache™ 2.0 technology, which boosts performance for fast burst and high sustained sequential write speeds. Its multi-tiered caching architecture uses a combination of SLC and TLC blocks to maximize read/ write operations and improve responsiveness and longevity, making it the ideal storage solution for multi-tasking and heavy workloads such as photo and video editing, as well as office productivity applications. 

Ultra-durable systems with high-grade endurance
DataGuard™ Client technology and LDPC error correction mean that the X400 SSD delivers high reliability and endurance up to 320 terabytes written (TBW)2. A dedicated onthe-fly hardware core performs progressive error correction to minimize the impact on latency and
performance, while maintaining low power usage. The X400 SSD product family includes a 5-year warranty.

TCG Opal 2.0 Support
TCG Opal 2.0 support means interoperability with 3rd party leading security Independent Software Vendors (ISVs). The X400 SSD includes Self-Encrypted Drive (SED) capabilities to protect data at rest through hardware-based 256-bit AES encryption. Corporate IT customers have peace of mind knowing their business-critical data is protected, secured and encrypted, while providing performance and reliability to its employees.
