Toshiba Announces Enterprise Read Intensive SSD for Servers

Toshiba today unveiled the HK3R enterprise solid state drive, a 2.5-inch, 6Gb/s SATA eSSD integrated with Toshiba 19nm NAND flash.

The HK3R eSSD is optimized for read-intensive applications such as read-caching, error logging, boot, and low-duty storage applications requiring power-loss-protection and end-to-end data protection features.

It incorporates Toshiba proprietary QSBC (Quadruple Swing-By Code) error-correction technology and it is available in capacities up to 480 GB. According to Toshiba, the HK3R series drives achieve sequential read speeds of 500MiB/s and Random Read speeds of 75,000 IOPS. The 240GB and 480GB drives achieve sequential write speeds of 400MiB/s and random write speeds up to 12,000 IOPS, while the 120GB drive reaches sequential write speeds of 280MiB/s and random write speeds of 10,000 IOPS.

The drive also supports one full drive write per day with a one hundred percent random data, aligned 4KiB workload. Additionally, the eSSD carries a 5-year limited warranty.

Toshiba will begin sampling the HK3R 120GB, 240 GB and 480GB in December 2013.
