Seagate has updated its Cheetah 15K enterprise-oriented hard disk drive line-up with a model that incorporates perpendicular recording technology and takes the 15,000rpm drive family's capacity to 300GB - more than double the current top-of-the-line model's 147GB.

The Cheetah 15K.5 will ship to the channel later this quarter, Seagate said, in 73GB and 147GB versions in addition to the 300GB model. The drives will be offered with a choice of 3Gbps Serial-attached SCSI (SAS), Ultra320 SCSI or 4Gbps Fibre Channel interfaces. Server and storage system OEMs are getting product already.

Like the current 15K.4 line-up, the new model has a mean time between failures (MTBF) of 1.4m hours at full duty cycle, Seagate said. However, it's 30 per cent faster, the company claimed. ®
