SATA - Serial Advanced Technology Attachment
Serial Advanced Technology Attachment is a serial interface standard used to control and transfer data from mass storage devices such as hard disk drives and optical drives.
SATA was designed to replace older Parallel ATA or PATA interface for connecting hard disk drives to motherboards, to increase system performance and efficiency with great reduction in development costs.
Advantages of SATA (over PATA)
- SATA uses long and thin cables which are less bulky and fragile than the old Parallel ATA cables.
- It uses 7-pin data connector as compared to the 40-pin connector in Parallel ATA.
- The old PATA cables were bulkier which block airflow and induce heat in the motherboard. SATA cables are easy to install and gives more space for other cables to be installed on the motherboard.
- The data speed varies in the range 1.5 Gbps to 6.0 Gbps.
