The ATA hard disk drives or the Advanced Technology Attachment hard disk drives usually come in Serial as well as the Parallel IDE formats. The Serial ATA is called as the SATA. The concept of the SATA was introduced in the year of 1986. A simple definition of the SATA can be that it can be called as the serial version of the ATA or the IDE interface. This concept of the SATA was ratified by the ANSI in year of 2002. it can be considered as the next generation technology.
The advantage of the SATA is that it has the capability to provide point to point channel communication between mother board or the main board and the drive. Where as in the Parallel ATA that can be termed as the PATA the architecture of the master slave combination is supported on a single cable for the two drives it supports.
The SATA is also used in the implementation of the RAID. The primary reason for the design of the SATA is for the transfer of the data from and to the hard disk drives. The SATA is actually a bus that gives a high performance of data transfer. The data transmission is achieved in the in the half duplex channel.
The speed of the data transmission is about 1.5 giga bits per second or 150 mega bytes per second. This is a unidirectional. Eventually the SATA II was introduced in the year of 2003 that has the speed of about 3 giga bits per second or 300 mega bytes per second. The Parallel ATA hard disk drive uses the flat cable that has the width of around 18’’. But in the case of the Serial ATA a four wire cable is used that has a length of one meter.
