1.3SATA

The ATA (Advanced Technology Attachment) interface which was developed based on the IDE (Integrated Drive Electronics) has been around from 1980’s. As the PC processor speed has improved, so have the data rates of the HDD. The parallel ATA is reaching its limit of 133 MB/s data transfer rate. Serial implementation of ATA (SATA) will allow the data rate to run even faster so the processor will be utilized more efficiently. Serial ATA has been developed to provide the next generation storage interface.

SATA interface replaces 2 inch wide, 40 pin parallel interface connector with 0.25 inch wide 7 pin serial interface connector. The maximum length of the SATA interface cable can be extended to 1 meter (approximately 39 inches) compared to 18 inch of parallel ATA. SATA also allows a data transfer speed of 150 MB/s, 300 MB/s, and 600 MB/s. Even though SATA will not directly interface w i t h P a r a l l e l o r t r a d i t i o n a l A T A (PATA) hardware, it is compliant with ATA protocol and therefore software compatible. The cable geometry with smaller footprint connector reduces board space requirements and improves air flow and heat exchange inside computer systems.

SATA uses point to point connection topology and each channel works independently. There is no sharing of interface, master/slave drive configuration, and no master/slave jumper settings. This is different from Parallel ATA (PATA) architecture where 2 drives per port are supported by a shared bus and drives are designated as master or slave drive based on jumper pin or cable selection. Unlike parallel ATA, SATA drives are hot-plug and hot-swappable.
