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. DataGuard Client technology and LDPC error correction mean that the X400 SSD delivers high reliability and endurance up to 320 terabytes written (TBW). 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 means interoperability with 3rd party leading security Independent Software Vendors (ISVs).
