Seagate unveils power-conscious 10K drive

By Kevin Komiega

—Seagate Technology today announced a new hard disk drive that strikes a balance among capacity, performance, and power consumption. The 10,000rpm Cheetah NS drive is based on the same platform as the 15,000rpm Cheetah 15K.5, but includes Seagate's new PowerTrim technology for more-efficient power consumption.

The Cheetah NS also features up to 33% more capacity at 400GB, along with a 33%
reduction in power and cooling requirements. This additional capacity and reduced cooling profile in the data center means the Cheetah NS ultimately delivers a lower total cost of ownership.

"We took the 15K Cheetah drive design and boosted the capacity to give us an extra 100GB without losing too much in the way of performance," says Willis Whittington, senior product marketing manager for Seagate's Enterprise Compute Business. "We didn't change anything in the mechanics. The only thing we changed is the head design."

Power consumption for the Cheetah NS drive is rated as low as 8 watts. The result is a 34% reduction of power in idle mode, as well as a 33% reduction in operating power compared to other 10,000rpm drives.

Whittington says users looking for higher IOPS-per-gigabyte transactional performance are likely to opt for the Cheetah 15K.5, while the new Cheetah NS is designed for users in search of a higher-capacity, lower-cost option.

The Cheetah NS has a seek time of 3.9ms and is available with a choice of interfaces, including 3Gbps Serial Attached SCSI (SAS) or 4Gbps Fibre Channel. The drive is rated at a mean time between failure (MTBF) of 1.4 million hours and has a five-year warranty.

Seagate is now shipping the Cheetah NS to OEM customers, and the drive is expected to be available to the distribution channel during the third quarter of 2007.
