DOREMI CHTA146X15

Model Details

The new Cheetah 15K disc drive employs innovative perpendicular recording technology to set new standards for storage costeffectiveness. While doubling available capacity to 300GB, the Cheetah 15K also delivers 36 percent higher sequential performance. This enables enterprises to meet their throughput and capacity requirements with fewer drives, significantly reducing total cost of ownership (TCO).

the Cheetah 15K designed for maximum reliability in demanding enterprise
applications, including a nonrecoverable error rate that’s been improved by a factor of 10. Cheetah 15K incorporates such Seagate-exclusive features as IRAW (Idle Read After Write), enhanced ECC (Error Correction Code) and BMS(Background Media Scan) to safeguard data integrity in the most rigorous environments.

Features:

16-MB cache

Ultra320 SCSI 80-pin interface

Perpendicular recording technology for maximum capacity

Up to 125-MB/s sustained transfer rate

30 percent more IOPS than 10K 3.5-inch drives

Reduced RAID rebuild times

Highest reliability rating in the industry

Lower total cost of ownership (TCO)
