300GB to 900GB 3.5" Serial Attached SCSI (SAS) Hard Drives

Serial Attached SCSI (SAS) is a data transfer protocol that is more enterprise focussed than SATA, which is the standard bus for regular consumer drives. Available in 300GB, 600GB and 900GB capacities SAS drives are more expensive per gigabyte, but they offer increased speed, longevity and improved error checking, which is vital for their intended use in enterprise, server and high-end workstation solutions. These 3.5" models are less limited in speed and capacity than 2.5" ones, but require more space. Designed to be used with mission critical systems such as servers, high-end work stations or any other users that require the best performance going to improve their systems performance.
