SATA

SATA

(Serial ATA) The standard hardware interface for connecting hard drives, solid state drives (SSDs) and CD/DVD drives to the computer. Introduced in 2001, all computers for consumer use employ the SATA interface. However, servers and high-end workstations may use the SCSI interface (see serial attached SCSI).

SATA, PATA and IDE
SATA is the faster serial version of the parallel ATA (PATA) interface. Both SATA and PATA are "integrated drive electronics" (IDE) devices, which means the controller is in the drive, and only a simple circuit is required on the motherboard. See IDE, mSATA and SATA Express.

External eSATA and eSATAp Drives
Some computer motherboards have eSATA ports for external SATA drives. The hybrid port (right) supports both SATA power and USB devices (see eSATA USB Hybrid Port).







SATA and PATA Cables
SATA was welcomed by PC builders because the earlier PATA cables usurped most of the room inside the case. PATA connectors were also much larger. This transition motherboard supported both SATA and PATA drives.

External SATA Drive
External and laptop drives use 2.5" platters, whereas desktops typically use 3.5". The 2.5" drive (top) plugs directly into the sockets on this external case without extra wires. "Powered eSATAp" ports include the power, and the drive does not plug into an AC outlet.

Specifically, SATA infrastructure (including its PMs) presents the following challenges:
The two storage devices come with a front drive slot that allows a Micro SATA HDD or SSD drive to be added or removed like floppy media when connecting to hot swappable SATA ports or USB ports.
Evolving in parallel within the SATA movement is the new concept of MAID (Massive Arrays of Idle Disks) storage.
This new low-profile connector will enable more effective SATA integration in small form factor applications.
But now, with the advent of lower cost Serial ATA (SATA) disk drives and the increased amount of intelligence and enhanced data services available in SATA storage solutions, IT administrators have a cost-effective alternative to protecting their data.
The road to the world s first demonstration of SATA Express has been in development for almost 3 years.
