Definition HDD SATA

SATA is the development of ATA. SATA is defined as technology that is designed to replace the ATA in total. Adapter of serial ATA able to accommodate data transfers at speeds higher than the simple ATA.

The first-generation SATA interface known as SATA / 150 or SATA is often also referred to as SATA 1 communicating with a speed of 1.5 GB / s. His uncoded transfer speed is 1.2 GB / s. SATA / 150 have nearly the same speed with PATA / 133, but the latest version has many advantages SATA (such as native command queuing) which causes it to have more speed and the ability to do work in ling¬kungan multitask.

The initial period of SATA / 150, the maker of adapters and drives meng¬gunakan bridge chip to convert the existing design with PATA interface. The appliance bridge has a SATA connector and has some power connector. Gradually, products accommodate native SATA bridge. SATA is the current speed of 3GB / s and experts are now designing technology for SATA 6GB / s.
Some SATA features are:

1. SATA uses 4 signal line cable that allows more compact and inexpensive compared to PATA. 
2. SATA accommodate new features such as hot-swapping and native command queuing. 
3. SATA drives can be plugged into the controller Serial Attached SCSI (SAS) so that it can communicate with the same physical cable as native SAS disks, but SAS disks can not be plugged into the SATA controller.

Power cable and SATA cable undergo significant changes compared to Parallel ATA cable. SATA data cable using seven conductors where 4 of them are active for a data line. Therefore, a smaller form, SATA cables are easier to use in the room were more narrow and more efficient for cooling.
SATA is used for the type of hard disk, is a continuation of Serial Advanced Technology Attachment, a device that is on the computer motherboard. SATA typically use serial connection with thin wires, replace the series of parallel ATA (Advanced Technology Attachment) or also known as PATA (Parallel Advanced Technology Attachment).
The primary function of the SATA hard drive is to transmit data in serial mode. SATA hard drives in charge of transferring data between the motherboard and other devices which provide pemyimpanan, such as hard drives, CD-ROM drives, and other components, including the RAM (Random Access Memory) and the CPU (Central Processing Unit) computer. SATA also has support with all ATA and ATAPI (Advanced Technology Attachment with Packet Interface).
There are various types of Serial ATA, such as SATA 3Gb / s or SATA 2 or SATA II, which provides a transfer rate of 3 gigabits per second, and also became the name of the committee SATA-IO (Serial ATA International Organization) standard which defines the type of SATA. There is still a SATA 6Gb / s, SATA 1.5Gb / s or SATA I, which is able to provide 1.5gigabit per second transfer rate. While the SATA 6Gb / s has a double maximum reading speed of SATA 300.
While the SATA cable is a single cable or a serial link that has a minimum of four wires. SATA also comes with a cable flat when compared to PATA, with a series of thick wires. SATA cables can reach a length of 1 meter, while PATA can only be extended up to 40 cm.
For PC (Personal Computer), SATA I can use, but if for enterprise wide and require high transfer speeds, it can use the SATA II or SATA / 600, because it is more efficient and reliable. In addition, because the enterprise usually requires redundancy, efficiency and speed are important, so it is essential if using SATA. SATA II ports can be connected by two host connection in the drive, when the port can not be used, it can use other ports.
