A new hard disk drive announced by Hitachi, the Ultrastar 15K450 uses perpendicular magnetic recording (PMR) technology to deliver 450GB of storage, currently the highest available capacity in 15,000 RPM enterprise-class hard drives.
According to Hitachi, the new drive delivers 30 Percent more I/Os than its predecessor, with an average seek time of 3.3 milliseconds. The new drive will ship with either 3Gb/s Serial Attached SCSI (SAS) or 4Gb/s Fibre Channel (FC) interfaces.
Announced specifications are the following:
- 450GB (GB = 1 billion bytes, accessible capacity may be less)
- 183 billion bits per square inch maximum areal density
- 4 platters, 8 recording heads
- 2090 Mb/s max. media data rate
- 3.6 ms average seek time (with command overhead)
- 15,000 RPM, 2.0 ms average latency
- 3Gb/s SAS, 4Gb/s FCAL interfaces
- 16 MB data buffer
- 25.8 mm in height (max)
- 750 in weight (max)
- 250 G/2 ms pulse non-operating shock
- SAS: 13.3 watt idle power
- FCAL: 13.4 watt idle power
- 3.7 Bels typical idle acoustics
- 5 to 55 degrees C operating temperature
