The bandwidth throughput of Serial ATA 1.5Gb/s is the same as of PATA/133, but the new devices of SATA offer the NCQ feature. The devices of this Serial ATA interface were widely used in office and personal desktop computers. It does not offer native command queuing. But, 1.2 Gb/s (150 Megabyte/s) is the actual uncoded transfer speed of this revision. This first-generation communicates with a speed of 1.5 Gigabit per second. The official name of this version is Serial ATA 1.5 Gbit/s. It is the first version of the SATA interface, which was released on 7 th January in 2003. Let's discuss each revision of the SATA interface in detail one by one: SATA Revision 1.0 It is the third generation of SATA, whose speed is running at 6.0 Gigabit per second. SATA III: This interface is formally called SATA 6Gb/s. It is the second generation of SATA, whose speed is running at 3.0 Gigabit per second. SATA II: This interface is formally called SATA 3Gb/s. It is the first generation of SATA, whose speed is running at 1.5 Gigabit per second. SATA I: This interface is formally called SATA 1.5Gb/s. SATA-SATA: It is a standard data cable which is available in various lengths and can be used for standard SATA applications.įollowing are the three major different revisions of the SATA interface:.Micro SATA: This SATA cable is used for internal disks and backplane applications.This SATA cable can be used easily with longer graphic cards. Low Profile SATA: It is a quite thin SATA cable with a very simple and low profile connector.
This interface is a bridge between the SATA devices.
Some other different types of SATA cables are given below: Let's discuss other types of serial ATA cable one by one.
The SATA cables are long, and both end-points of the cable are thin and flat. eSATA drives are hot-swappable and providing high transmitting speed with no USB and FireWire issues.įast transmission speed, high performance, and outstanding storage capacity are the two main characteristics of SATA hard drives.
External SATA is commonly referred to as eSATA. SATA also uses external hard drives through external SATA. In comparison to earlier ribbon cables which are used with ATA drives, the cable of serial ATA provides the best airflow in the computer systems and makes the routing easier. The first version of SATA (SATA 1.0) can easily communicate 1.5 Gbps of performance to each storage drive within a disk array. In 2008, the Serial ATA hard drive replaced the parallel ATA in the consumer's desktop and laptop computers. In January 2003, Seagate Barracuda SATA V was the first hard disk drive in the world. Serial ATA was introduced to provide various benefits over the previous Parallel ATA interface, which was announced around the 1980s. Serial ATA (SATA) was created by the serial ATA working group in 2000. SATA standards help in transferring data from hard drives and optical disk drives to computer systems. Serial ATA or SATA is a computer bus interface for connecting the storage disks or drives to the motherboard of computer systems. The name "AT" Attachment was introduced after the invention of the IBM personal computer in 1984. SATA is abbreviated as Serial AT Attachment.
