Seagate ST373455SS SAS Hard Disk Drive

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