HK4 Series is Toshiba’s first enterprise SSD to embed 15nm MLC NAND flash memory for enterprise and data centre applications
Düsseldorf, Germany, 23rd February, 2016 – Toshiba Electronics Europe (TEE) announces 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 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 Datacenters can rely on for all of their Solid-State Storage needs,” said Don Jeanette, TrendFocus’s NAND and SSD research vice president.
“The HK4 Series joins our family of SATA SSDs and is designed to meet the needs of our customers who are looking for a SATA SSD with low operating power, excellent quality of service, high capacity and with encryption,” said Martin Larsson, vice president of Toshiba Electronics Europe, Storage Products Division. “Knowing that security and encryption is a priority for our customers, we are thrilled to release a SATA SSD that meets those needs.”
Offered with a five-year limited warranty, the HK4 Series is available now. The self-encrypting drives will be available in April 2016. For more information on Toshiba’s line-up of industry-leading SSDs, HDDs and SSHDs visit www.toshiba.semicon-storage.com.
 Definition of capacity: Toshiba defines a megabyte (MB) as 1,000,000 bytes, a gigabyte (GB) as 1,000,000,000 bytes and a terabyte (TB) as 1,000,000,000,000 bytes. A computer operating system, however, reports storage capacity using powers of 2 for the definition of 1TB = 240 = 1,099,511,627,776 bytes and therefore shows less storage capacity. Available storage capacity (including examples of various media files) will vary based on file size, formatting, settings, software and operating system, such as Microsoft Operating System and/or pre-installed software applications, or media content. Actual formatted capacity may vary.
 DWPD: Drive Write Per Day. One full drive write per day means the drive can be written and re-written to full capacity once a day every day for five years, the stated product warranty period. Actual results may vary due to system configuration, usage and other factors.
