Toshiba Announces HK3R SATA III Enterprise SSD For Read-Intensive Applications

Toshiba Digital Media Network Taiwan Corporation, a global technology innovator, is announcing the HK3R series of enterprise solid-state drives (eSSD).  Optimized for read-intensive applications, the HK3R series are suitable for tasks such as read-caching, boot, error logging, and low-duty storage usage that requires end-to-end data protection and power-loss protection.  The HK3R series feature Toshiba’s own proprietary QSBCTM (Quadruple Swing-By Code) error-correction technology, which is a high-efficiency error correction code (ECC) that ensures data safety and integrity.

Toshiba’s SATA III (6 GB/s) HK3R series feature Toshiba 19nm MLC NAND flash housed in a standard 2.5″ form factor, and will be available in capacities of 120GB, 240Gb and 480GB.  Sequential read speeds are stated as 500 MB/s for all three capacities.  Sequential write speeds are 280 MB/s for the 120Gb version, and 400 MB/s for the larger two capacities.  Random 4K read speeds are 75,000 IOPS for all three capacities, while random 4K write speeds are shown as 10,000 IOPS for the 120GB model and 12,000 IOPS for the two larger versions.

According to Mr. Kashiwabara, Senior Manager of Marketing Section, Toshiba Digital Media Network Corporation, “Toshiba recognizes the importance of eSSD reliability and designs our eSSDs with full power loss protection and QSBC error protection technology to put our customers’ minds at ease.  Toshiba understands that keeping enterprise data safe and accessible is of the utmost importance.”

The HK3R series support up to one full drive write per day, and retain sustained and consistent performance over the life of the drive.  Toshiba is backing the HK3R series with a five-year warranty.  Samples are anticipated to begin shipping later this month.
