Since 2002, hard drives are offered with Serial ATA (S-ATA or SATA) interface. The advantages over ATA are the higher possible throughput and simplified cable management. Extended versions of SATA have more, especially for professional applications relevant, features such as the ability to share data sources during operation (Hot-plug). The Computer Accessories Store offers different types of external hard drives for your computer.
Meanwhile, SATA has practically enforced, the latest drives are no longer offered as an IDE versions, since the theoretically possible for IDE transfer rates are nearly reached. In 2005 the first hard drives with Serial Attached SCSI (SAS) were presented as a potential successor to SCSI for server and storage area. This standard is partially backward compatible to SATA.
The SAS technique is based on the established SCSI technology, but sends the data serially, connects the devices via a common bus but not individually using dedicated ports (or port multiplier).
