Toshiba has released the HK4, a new enterprise 6.0 Gbit/s SATA solid-state drive (SSD) series designed for read-intensive and value-endurance workloads. The HK4 Series is Toshiba’s first SSD for enterprise and data centre applications to embed 15nm MLC NAND flash memory and offers low latency tuned for high quality of service (QoS).

The read-intensive HK4R Series combines capacities up to 1.92TB with low operating power and is suitable for enterprise applications such as web servers, files servers, media streaming, video-on-demand, search engines and warm data storage.

The HK4E value-endurance drive offers an endurance level of three DWPD (drive write per day) and a capacity up to 1600GB. It is well suited for data centres and mixed workload applications.

The HK4 Series is Toshiba’s first SATA SSD with optional Trusted Computing Group (TCG) enterprise encryption support and is also equipped with Toshiba’s QSBC (Quadruple Swing-By Code) error technology. This proprietary QSBC error-correction technology is a highly efficient error correction code (ECC) that helps protect customer data from corruption caused by NAND flash memory media wear. This improves reliability and extends life of Toshiba SSDs.

“With the introduction of a leading edge SATA drive, Toshiba has strengthened their portfolio of SSDs and is rapidly becoming a supplier that Enterprises and data centres can rely on for all of their Solid-State Storage needs,” said Don Jeanette, TrendFocus’s NAND and SSD research vice president.
