Hitachi Datasystems (HDS) Corp. Monday announced it will offer flash-based solid-state drives (SSDs) for its high-end Hitachi Universal Storage Platform V and VM storage arrays.
Roberto Basilio, vice-president of storage platforms product management for HDS, said that the SSDs — expected to become available near the end of January — will offer hundreds of times the I/O per second (IOPS) current Fibre Channel hard drive technology does. Basilio added that SSDs are likely to become available in HDS’ midrange storage array systems in the future.
“One array of solid state disks — say eight drives — can give you 40,000 IOPS. To do the same with Fibre Channel disks would require hundreds of drives,” he said. Hitachi said pricing for the drives is not yet available, but SSDs are typically up to 40 times more expensive than enterprise-class hard drives. According to IDC, enterprise-class spinning disks cost about 90 cents per gigabyte while enterprise-class SSDs are US$35 to $40 per gigabyte.
According to IDC, HDS’ announcement shows the possibilities for a high IOPS class of SSDs targeted at tier 0 applications that can use the highest level of fast-access storage. SSDs offer a number of benefits over HDDs, including better IOPS performance, lower power consumption, less heat generation, lower acoustical noise, and form factor flexibility.
HDS’ SDD announcement follows similar ones by vendors such as EMC , Sun Microsystems Inc. and Hewlett-Packard Co.
