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.
