S-AS 8087 to 8087 Transfer Cable Replacement 50cm S-AS SFF 8087 to SFF 8087 Server Hard Disk Data Cable

S-AS (Serial Attached ) is a generation of technology, which is the same as the popular Serial ATA (SATA) hard disk. It uses serial technology to obtain better transmission speed and shorten the connection cable. Improve internal space, etc.
S-AS is a interface developed after the parallel interface. This interface is designed to improve the performance, availability, and expandability of the storage system, and to provide compatibility with SATA hard drives.
S-AS interface technology can be backward compatible with SATA. Specifically, the compatibility of the two is mainly reflected in the compatibility of the physical layer and the protocol layer.
At the physical layer, the S-AS interface and the SATA interface are fully compatible. SATA hard disks can be used directly in the S-AS environment.
From the interface standard, SATA is a sub-standard of S-AS. Therefore, the S-AS controller can directly control SATA hard disks. However, it cannot be used directly in the SATA environment, because the SATA controller cannot control the S-AS hard disk;
