SATA
Serial Advanced Technology Attachment : Bus connection between the motherboard and a unit mass memory, Eg HDD.
Evolution, including the adoption of serial mode, the ATA bus, also called IDE (Integrated Drive Electronics) And now by opposition P-ATA Parallel ATA.
Appearing in 2003, this standard has improved the speed of transfer. The flow theoretical 150 Mb / s and 300 Mb / s for SATA II version, against 133 MB / s P-Ata with the Protocol Ultra DMA.
It's just an irony of history because, before, the parallel connection allowed higher speeds. But increasing the speed at which electronic works reversed the logic. On a serial link, you can send a sequence of bits frequency very high, that does not tolerate a parallel link.
Moreover, the serial mode has other advantages: connectors and cables smaller maximum length of cable greater.
