The difference between SATA and ATA

SATA is the development of the ATA. SATA is defined as a technology designed to replace the ATA in total. Of serial ATA adapter to accommodate the data transfer at speeds higher than simple ATA.
The first-generation SATA interface known as SATA/150 or often referred to as SATA 1. 1 communicates with the speed of SATA 1.5 GB / s. Its uncoded transfer rate is 1.2 GB / s. SATA/150 have nearly the same speed with PATA/133, but the latest version of the SATA has many advantages (such as native command queuing) which causes it to have more speed and the ability to perform work in multitask environment ling.
In the early period of SATA/150, the adapter and drive makers to use the bridge chip to convert the existing design with PATA interface. The device has a connector SATA bridge and has some power connectors. Gradually, the bridge to accommodate native SATA products. Current speed of SATA is 3GB / s, and experts are now designing technology for SATA 6Gb / s.


AT Attachment (ATA) is a standard interface for connecting storage devices such as hard disk, CD-ROM drive, or DVD-ROM in your computer.
ATA stands for Advanced Technology Attachment. ATA Standard is managed by a committee named X3/INCITS T13. ATA also has several other names, such as IDE and ATAPI. Due to the introduction of the latest version of the ATA is called Serial ATA, ATA version was later renamed Parallel ATA (PATA) to distinguish it from Serial ATA is a new version.
Parallel ATA only allows a maximum cable length is only 18 inches (46 cm), although there are many products available on the market that has a length of up to 36 inches (91 cm). Due to the short distance, PATA is only suitable for use in the computer alone. PATA is very inexpensive and commonly found in computers.
