Definition – What does SATA?
SATA (Serial Advanced Technology Attachment) is an interface used to connect ATA hard drive to the computer’s motherboard. Its transfer rates start at 150MB that is significantly faster than even the fastest 100MB drives. SATA interface is an update to the parallel signaling standard of the 1980s used for improved integrated drive electronics and the earlier integrated drive electronics (IDE).
Glossary Web explains SATA
It was introduced in 2005 and in 2010, it was updated to use a data cable with seven conductors made up of three rounds and four active two-pair data lines with wafer connectors at each end. SATA offers numerous advantages over ATA and PATA, and the most improved features are hot swapping and faster data transfer rates. The hot swapping is the ability to replace a computer system component without having to shut down the system. Older system had to be shut down before replacing or installing system modules. Its 6GB data transfer rate is also a lot faster as compared to all the other ATA and PATA.
The standard interface for SATA is the AHCI (advanced host controller interface) that includes innovative features such as native command queuing, hot swapping and more. If the chipset or motherboard does not support ACHI, it will typically run in IDE emulation mode that does not support advanced features. Overall, SATA is better and more efficient than the dated PATA standard. If you are looking to buy a new computer that will fast hard drives for the year to come, make sure it comes with SATA interface.
