But increasing bandwidth and flexibility demands have exposed inefficiencies in the two main parallel interface technologies - SCSI and ATA.

While parallel technologies meet most performance requirements of today's enterprise solutions, continued demands for higher speeds, more robust data integrity, smaller designs and wider standardization cast doubt that parallel technology can economically keep pace with increasing CPU processing power and disk drive speeds. Parallel technology poses still other challenges: Parallel transmissions are susceptible to crosstalk across wide ribbon cable paths that add line noise and can cause signal errors - a pitfall that has been remedied by slowing the signal, limiting cable length, or both.

Terminating parallel signals is another difficulty, requiring individual lines to be terminated, usually by the last drive, to avoid signal reflection at the end of a cable. Finally, parallel's large cable and connector size make it unsuitable for increasingly dense computing environments. The technology draws its name from the way it transmits signals - in a single stream, or serially, compared to the multiple streams found in parallel technology.

The main advantage of serial technology is that while it moves data in a single stream, it does so much faster than parallel technology because it is not tied to a particular clock speed.

Serial technology wraps many bits of data into packets then transfers the packets at a much higher speed than parallel up to 30 times faster down the wire to or from the host. Due to its lower cost per gigabyte, SATA will continue as the prevalent disk interface technology in desktop PCs and sub-entry servers and networked storage systems where cost is a primary concern.

USM Slim reduces thickness of Universal Storage Module USM ; DevSleep enables lower power consumption for always-on devices while they are in low-power modes; Hybrid Information provides higher performance for solid-state hybrid drives.

Faster SATA implementations are backward compatible with older devices. Maximum unshielded cable length is about 1 meter. SATA-I is 1. However you can replace one internal 3.
