Available in capacities of 120GB, 240GB and 480GB, the new HK3R eSSDs signal an expansion of Toshiba's range of Enterprise-class SSDs. Designed for use in tiered server storage systems, the new eSSDs are ideal for use in read-intensive applications such as fast boot drives and for cache and error logging.

Coming in 2.5 inch (6.4cm) form factor and fitted with a 6Gbit/s SATA 3.0 interface, the HK3R eSSDs employ state-of-the-art 19nm MLC NAND which enable the series to 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.

Designed to accomodate 1 full drive write per day with 100% random data workload for 5 years, all HK3R eSSDs feature full power loss protection and end-to-end data protection. The drives also incorporate Toshiba’s Quadruple Swing-By Code (QSBC) for improved error correction and reliability.

Samples of the HK3R range will be available during December.
