Serial ATA (SATA, abbreviated from Serial AT Attachment) is a computer bus interface that connects most of the hard disk and solid-state drives on the market today. Serial Attached SCSI (SAS) is a point-to-point protocol that is primarily used to connect high-end server, workstation, and enterprise hard disk drives, as well as LTO Ultrium tape drives, offering superior performance compared to sas hard drive connections. MDS has a complete line of appliance solutions that enable you to make quick clones of SATA and sas hard drive connector drives, whether you have a few drives or thousands of drives.
