Seagate ST373455SS SAS Hard Disk Drives

Seagate Cheetah 15K.5 73GB 15K 3.0Gbps Serial SCSI / SAS Hard Drive - Refurbished

The Seagate® Cheetah 15K.5 hard drive is the first to break the 100-MB/s sustained transfer rate barrier. These drives lead the industry in reliability, performance and value by delivering higher throughput with fewer drives than conventional 10K-RPM solutions . The Cheetah 15K.5 enterprise hard drive sets a new standard for storage cost effectiveness with an unprecedented blend of storage performance, capacity and reliability.

All SAS compatible servers including:
Dell PowerEdge 840, 1900, 1950, 1950 III, 2900, 2900 III, 2950, 2950 III, 2970, 6900, 6950, R300, R900, R905, T300, T605 Servers and PowerVault MD1000, MD3000, NF100, NF500, NF600 Storage Arrays
