A Dell PowerEdge Server
May 26, 2008 Dell is the first computer supplier to ship server and storage systems using high performance 450GB SAS disk drives based on Hitachi's new Ultrastar 15K450. The 3.5-inch, 15,000 RPM drives deliver 450GB of storage and a 30 percent improvement generation-to-generation in sequential throughput. They also have 50 percent more available capacity than their 300GB predecessors, but similar low power characteristics. The drive features average seek times as low as 3.3 milliseconds and the fast rotational speeds reduce average latency time to 2 milliseconds. The drives are available with either 3Gb/s Serial Attached SCSI (SAS) or 4Gb/s Fibre Channel (FC) interfaces.
