Welcome to the store! SAS (Serial Attached SCSI) is a new generation of SCSI technology, similar to Serial ATA (SATA) hard drives. It uses serial technology to achieve higher transfer speeds and shorter connection lines, improving internal space. SAS is a new interface developed after the parallel SCSI interface, designed to enhance the performance, availability, and scalability of your storage system and provide compatibility with SATA devices. High-density (HD) MiniSAS SFF-8643 internal cable assemblies are available for SAS 2.1, 6Gb/s and SAS 3.0, 12Gb/s specifications. SFF‑8643 is a new connector that takes up less PCB space and allows for higher port density for internal hosts and devices. The mixed version of these new cables will enable a smooth transition from 6 Gb to 12 Gb.
