SAS Cable (Internal)

Internal SAS cabling links Serial Attached SCSI drives to a controller inside enterprise servers, carrying up to 22.5 Gbps per lane. Dual-port wiring gives each drive two independent paths, a redundancy that keeps storage reachable if one connection or controller fails. The protocol's roots in SCSI bring deep command queuing and error handling suited to always-on server workloads. A 1-meter length spans the distance from a RAID or host bus adapter to a drive backplane within a chassis. It is strictly an internal, enterprise-grade component rather than a consumer accessory. Cables typically cost $10 to $25.
