Serial Attached SCSI (SAS) provides a superior storage solution. With some storage requirements escalating & others becoming more complex, factors such as flexibility, performance, increased reliability, greater density, security, scalability & 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) & redundant data paths to the drive, e.g. disk backup, archival, reference, & other highly available applications.
