Serial ATA
by rob
Serial ATA (SATA) is the next step in hard drive evolution based on ATA standards. Parallel ATA (also known as IDE) is the current standard, but it's reaching the physical and electronic limitations of the circuitry, cabling and disk drives. Parallel ATA data transfer rates only support up to 133 MB/s while current SATA transfer rates start at 150 MB/s; second and third generation drives deliver transfer rates of 300 and 600 MB/s respectively. A major feature of SATA is the data cable. At only 1/4" wide it allows for better airflow/thermal dynamics and it is very easy to connect. Also, there are no jumpers to set, no master/slave configuration, less power consumption and enhanced data protection.
