Serial Attached SCSI SAS is a high-speed data storage interface designed for high-throughput and fast data access. Intended primarily for data storage centers, the SAS interface is backwards compatible with SATA. This allows the user to mix more expensive, lower-capacity SAS drives for applications that require faster data access and higher reliability, with lower-cost, higher-capacity SATA drives for applications with lower access speed requirements. Monoprice carries a full line of quality SAS cables with connectors for every possible application, both internal and external. This 2 meter long cable uses 28 AWG wires and is intended for external use. It has a 34-pin SFF-8470 male SAS plug with locking thumbscrews on each end.
