What is SATA?

User Rating:  / 0
SATA stands for Serial Advanced Technology Attachment. This is an interface for connecting hard drives to a computer. Unlike IDE which uses parallel signaling, SATA uses serial signaling technology. Because of this the SATA cables are thinner than the ribbon cables used by IDE hard drives. SATA cables can also be longer allowing you to connect to more distant devices without fear of signal interference. There is also more room to grow with data transfer speeds starting at 150 MB/s.
