1. ATA
Most types of drives used by computer users type, Almaty (or better known as IDE drives). ATA is based on the type of standards in 1986, the use of 16-bit parallel, and continue to grow, additional speed and size of the disk. Ultimate criterion is the Alma-Ata 7 for the first time in 2001, introduced T13 Committee (the committee responsible for determining the standard ATA).Type of Almaty – 7 with a data transfer 133 MB / sec. Later in the year 2000 set the standard for the Parallel ATA has a data rate of 133 MB / sec, parallel ATA, but there are many signals on the issue of thymine, electromagnetic interference (interference electromognetic) and intergitas data. Then, the industry to solve these problems caused by the parallel ATA, and create a new standard called Serial ATA (SATA).
Almaty (Advanced Technology Attachment) using 16-bit parallel is used to control computer equipment, and has been used more than 18 years of standards. The difference between SATA and ATA is the most simple data and power lines are different.
ATA standards, such as Western Digital 200GB model, there is a two-inch ribbon cable and 40-pin data connections and the need to 5V for each pin 4-pin connection. At the same time, such as SATA 120 GB Western Digital model, there is one and a half-inch wide, 7 interface, so the data connection thinner, more easily managed data kebel. SATA data cable the maximum length of 1 meter (39.37 inches) longer than the Alma-Ata, only 18 inches.
2. The SATA
With the 15-pin SATA power lines and 250 mV, a clear need for more power than the 4-pin Almaty, but in fact are the same. Capable of the best achievements of SATA is the largest amount of bandwidth available for the 150 MB / sec.
Other advantages of the SATA SATA is to make hot-swap capability, so that it can turn off, turn not turn off computer systems.
Although the prices are more expensive than SATA drives slightly ATA drives, SATA is kesimpulanya advantage over ATA connectors, power supply, the most important performance.ATA standard has begun to the left and the producers choose SATA standard.
IDE (Integrated Drive Electronics) is a standard interface, the computer motherboard data bus between the disk storage. IDE interface to create the IBM PC Industry Standard Architecture (ISA) 16-bit bus. The IDE interface is the interface to storage devices, you can teringrasi to a disk or CD – ROM drive. Although the IDE is a general technology, most people use the term to refer to the IDE, ATA specification. Although the AHCI (Advanced Host Controller Interface) is a hardware mechanism to make the software as a communication of the SATA host bus adapter is designed for hot plug and Native Command Queuing (NCQ), which can increase the capacity of the computer / system / hard disk, in particular, is a multi-tasking environment, allowing the drive to perform read and write commands to send random order, to optimize the head movement, in the process of reading. AHCI supports a variety of operating systems, such as Windows Vista, and Linux kernel 2.6.19.
