Serial Attached SCSI (SAS) provides a superior storage solution. With some storage requirements escalating and others becoming more complex factors such as flexibility performance increased reliability greater density security scalability and accessibility are more critical than ever. SAS Midline hard drives are ideal for servers or external storage for high-capacity non mission-critical environments with less than 40% workloads requiring economical reliability (about twice that of entry drives) and redundant data paths to the drive e.g. disk backup archival reference and other highly available applications.
