Short for serial AT attachment, SATA 1.0 was first released in August 2001 and is a replacement for the parallel ATA interface used in IBM compatible computers. SerialATA is capable of delivering 1.5 Gbps (approximately 187 MBps) of performance to each drive within a disk array. It has the benefit of being backward-compatible with ATA and ATAPI devices, and offers a thin, small cable solution, as seen in the photo on the right. This cable helps make a much easier cable routing and offers better airflow in the computer when compared to the earlier ribbon cables used with ATA drives.
SATA also supports external drives through External SATA more commonly known as eSATA. eSATA offers many more advantages when compared to other solutions. For example, it is hot-swappable, supports faster transfer speeds with no bottleneck issues like USB and FireWire, and supports disk drive technologies such as S.M.A.R.T..
However, eSATA does have some disadvantages such as not distributing power through the cable like USB, which means drives require an external power source. The eSATA cable also supports a maximum length of up to 2 meters. Because of these disadvantages don't plan on eSATA becoming the only external solution for computers.
What hardware uses the SATA cable?
How many pins does SATA have?
There are two types of SATA cables. The SATA data cable that transmits the data between the drive and the motherboard has seven pins. The SATA power cable that connects to the power supply has fifteen pins.
How to you pronounce SATA?
SATA should always be pronounced as a full word or partial full word and never as each letter sounded out. However, its exact pronunciation is disputed. Many pronounce it as sah-tuh and others pronounce it say-tuh. It is also not uncommon to hear it pronounced as serial ay tee ay.
Because there has never been an official mention of how the SATA is pronounced, we suggest using whichever full word or partial full word version sounds best to you.
Because SATA is pronounced as a full or partial word, it should always be preceded with an "a" and not "an" in a sentence.
