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, for mission critical applications, servers and high-end workstations may use the SCSI serial interface instead (see serial attached SCSI).

eSATA and Powered eSATA
SATA drives are internal and cabled directly to the motherboard, while "eSATA" ports on the back of the computer accept external SATA drives. The "powered" version means the drive power comes from the port rather than the wall outlet.

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. Although SATA is an IDE technology, "IDE" refers to PATA (for details, see IDE, AHCI and PATA/SATA specifications). See mSATA and SATA Express.

eSATA Ports
These ports connect external SATA drives. The hybrid port supports both powered eSATA (eSATAp) and USB devices, and drives can be plugged in and out with the computer on (hot swappable). For more details, see eSATA USB Hybrid Port.







SATA and PATA Cables
SATA cables fit better inside the case than the stiff and cumbersome PATA ribbons. This earlier motherboard used SATA hard drives and PATA CD/DVD drives. Four SATA sockets took less room than one PATA.

In summary, if you want to fully utilize your SATA host port, then a port multiplier can provide expanded storage capacity and enhanced performance.
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.
