Enterprise SAS Drive Module

Serial Attached SCSI (SAS) drives feature a point-to-point interconnect to each drive, so each drive is electrically isolated from the others and multiple drives don't compete for bandwidth. This drive comes with 64MB of disk cache, operates at 7200 revolutions per minute and uses a protocol that enables fast data transfer to and from the hard drive.
