Hitachi launches a new enterprise hard drive
19 Apr 2008
Hitachi today announced the Ultrastar™ 15K450. The new drive uses perpendicular magnetic recording (PMR) technology to deliver 450GB of storage, currently the highest available capacity in 15,000 RPM enterprise-class hard drives. This hard drive would be suitable for servers and storage applications, such as online transaction processing, intensive database queries and other multi-user applications.
After tests conducted by Hitachi itself, Ultrastar 15K450 indicates a 30 per cent improvement as compared to its predecessor. The average seek time is just 3.3 milliseconds and because of the fast rotational speeds, the latency time reduces to as low as 2 milliseconds. The new drive will ship with either 3Gb/s Serial Attached SCSI (SAS) or 4Gb/s Fibre Channel (FC) interfaces.
''With the higher capacity and performance of the Ultrastar 15K450, enterprises are able to address their throughput requirements using fewer drives, which reduces three things; the cost of ownership, the datacenter's footprint and overall power requirements,'' said Dean Amini, director, enterprise market & strategy, Hitachi Global Storage Technologies. ''Coupled with our intensive testing and quality assurance process, the Ultrastar 15K450 offers the highest available performance and reliability for mission-critical computing environments.''
