What is Serial ATA Serial Advanced Technology Attachment or SATA Serial ATA Serial Advanced Technology Attachment or SATA is a standard for connecting and transferring data from hard disk drives HDDs to computer systems. As its name implies, SATA is based on serial signaling technology, unlike Integrated Drive Electronics IDE hard drives that use parallel signaling.

Serial ATA SATA, abbreviated from Serial AT Attachment is a computer bus interface that connects host bus adapters to mass storage devices such as hard disk drives.

SATA has several advantages over the Parallel ATA PATA hard drives developed in the 1. SATA cables are thinner, more flexible and less massive than the ribbon cables required for conventional PATA hard drives. Setting SATA controller modes. Serial ATA hard drives connect to a computers motherboard via SATA controller hardware that manages the flow of data. Putting SATA in IDE mode means the hard drive is recognized as a PATA device a situation that provides better compatibility with older hardware, but comes with the tradeoff of lower performance. Setting a SATA controller to Advanced Host Controller Interface AHCI offers higher performance than IDE mode, and also enables features such as hot swapping on SATA drives. The redundant array of independent disk RAID mode supports both AHCI functions and RAID data protection features. Technical differences between SATA and PATAThe SATA transport layer differs from PATA drives, in which data bits are delivered simultaneously across a 4. As its name suggests, a Serial ATA drive transfers data in serial fashion. Data is moved one bit at a time between a SATA drive and its host, using a seven pin data cable and 1. The SATA cable results in a higher signaling rate, which corresponds to faster throughput of data. SATA cables can be considerably longer than PATA ribbon cables, allowing a system designer more latitude in the physical layout of a system. Because there are fewer conductors, the risk of crosstalk and electromagnetic interference is lower. The signal voltage is much lower as well 2. SATA vs. 5 volts for PATA. SATA standards and revisions. The technical specifications governing Serial ATA device interfaces are authored by the nonprofit SATA IO industry consortium. The consortium has made several revisions to SATA standards to reflect increased data transfer rates. SATA Revision 1 devices were widely used in personal desktop and office computers, configured from PATA drives daisy chained together in a masterslave configuration. SATA Revision 1 devices topped out at a transfer rate of 1. Gbps. SATA Revision 2 devices doubled the transfer speed to 3. Gbps with the inclusion of port multipliers, port selectors and improved queuing. SATA Revision 3 interfaces support drive transfer rates up to 6 Gbps. SATA Revision 3 drives are backward compatible with SATA Revision 1 and SATA Revision 2 devices, albeit with a lower transfer speed. SATA Revision 3. 1 is an intermediate revision that added final design requirements for SATA Universal Storage Module for consumer based portable storage applications. SATA Revision 3. 2 added a specification known as SATA Express SATAe, which supports simultaneous use of SATA ports and PCI Express PCIe lanes. SATA design specs for flash storage. In 2. 00. 9, the SATA IO consortium unveiled the m. SATA specification for small form factor solid state drives SSDs. The M originally stood for mini, but that designation is no longer made and the specification is referred to as m. SATA. An m. SATA device is a flash drive that conforms to the SATA IO protocol specification and is mainly used in laptops, netbooks and other portable computing devices. The m. SATA specification maps Serial ATA signals to an internally mounted PCIe card in a computers motherboard. SATA SSD. The emerging M. SSD form factor is for ultrathin computing devices it is generally considered to be an eventual replacement for m. SATA. SATA compared to other storage protocols. The differences between SATAand SAS. SATA drives emerged initially as a method of near line storage and high performance secondary storage. Historically, Serial ATA has been viewed as a less costly alternative than Fibre Channel FC based storage area networks built to handle block storage. Advancements in SATA technology have helped narrow the gap with FC, particularly relating to SATAs performance reliability. Like its SATA counterpart, serial attached SCSI SAS employs thin cables to serially transmit data. SAS historically has been used by enterprises running large scale storage, particularly to support direct attached storage or hard drive controllers for enterprise server farms.
