Serial ATA SATA, abbreviated from Serial AT Attachment2 is a computer bus interface that connects host bus adapters to mass storage devices such as hard disk drives, optical drives, and solid state drives. Serial ATA succeeded the older Parallel ATA PATA standard,a offering several advantages over the older interface reduced cable size and cost seven conductors instead of 4. IO queuing protocol. Although, a number of hot plug PATA offering were first invented and marketed by Core International beginning in the late 1. Micro Channel architecture bus controllers. Before SATAs introduction in 2. PATA was simply known as ATA. Adobe Photoshop Cs3 Crack Keygen Avg. The AT Attachment ATA name originated after the 1.

The IBM ATs controller interface became a de facto industry interface for the inclusion of hard disks. AT was IBMs abbreviation for Advanced Technology thus, many companies and organizations indicate SATA is an abbreviation of Serial Advanced Technology Attachment however, the ATA specifications simply use the name AT Attachment, to avoid possible trademark issues with IBM. SATA host adapters and devices communicate via a high speed serial cable over two pairs of conductors. In contrast, parallel ATA the redesignation for the legacy ATA specifications uses a 1. To ensure backward compatibility with legacy ATA software and applications, SATA uses the same basic ATA and ATAPI command sets as legacy ATA devices. SATA has replaced parallel ATA in consumer desktop and laptop computers SATAs market share in the desktop PC market was 9. PATA has mostly been replaced by SATA for any use with PATA in declining use in industrial and embedded applications that use Compact. Flash CF storage, which was designed around the legacy PATA standard. A 2. 00. 8 standard, CFast to replace Compact. Flash is based on SATA. House Cards S03 Eztv more. Serial ATA industry compatibility specifications originate from the Serial ATA International Organization SATA IO. The SATA IO group collaboratively creates, reviews, ratifies, and publishes the interoperability specifications, the test cases and plugfests. As with many other industry compatibility standards, the SATA content ownership is transferred to other industry bodies primarily the INCITST1. ATA, the INCITS T1. SCSI, a subgroup of T1. Serial Attached SCSI SAS. The remainder of this article strives to use the SATA IO terminology and specifications. Featuresedit. SATA 6 Gbits controller, a PCI Express 1 card with Marvell chipset. HotplugeditThe Serial ATA Spec requirements for SATA device hot plugging, that is, devices and motherboards that meet the specification are capable of insertion removal of a device into from a backplane connector combined signal and power that has power on. After insertion, both the Device and Host initialize and then operate normally. The powered Host or Device is not necessarily in a quiescent state. Unlike PATA, both SATA and e. SATA support hotplugging by design. However, this feature requires proper support at the host, device drive, and operating system levels. In general, all SATA devices drives support hotplugging due to the requirements on the device side, also most SATA host adapters support this function. Advanced Host Controller InterfaceeditAdvanced Host Controller Interface AHCI is an open host controller interface published and used by Intel, which has become a de facto standard. It allows the use of advanced features of SATA such as hotplug and native command queuing NCQ. If AHCI is not enabled by the motherboard and chipset, SATA controllers typically operate in IDEb emulation mode, which does not allow access to device features not supported by the ATA also called IDE standard. Windows device drivers that are labeled as SATA are often running in IDE emulation mode unless they explicitly state that they are AHCI mode, in RAID mode, or a mode provided by a proprietary driver and command set that allowed access to SATAs advanced features before AHCI became popular. Modern versions of Microsoft Windows, Mac OS X, Free. BSD, Linux with version 2. Solaris and Open. Solaris, include support for AHCI, but older operating systems such as Windows XP do not. Even in those instances, a proprietary driver may have been created for a specific chipset, such as Intels. RevisionseditSATA revisions are often designated with a dash followed by roman numerals, e. SATA III,1. 2 to avoid confusion with the speed, which is always displayed in Arabic numerals, e. SATA 6 Gbits. SATA revision 1. Gbits, 1. 50 MBs, Serial ATA 1. Revision 1. 0a2 was released on January 7, 2. First generation SATA interfaces, now known as SATA 1. Gbits, communicate at a rate of 1. Gbits,c and do not support Native Command Queuing NCQ. Taking 8b1. 0b encoding overhead into account, they have an actual uncoded transfer rate of 1. Gbits 1. 50 MBs. The theoretical burst throughput of SATA 1. Gbits is similar to that of PATA1. SATA devices offer enhancements such as NCQ, which improve performance in a multitasking environment. During the initial period after SATA 1. Gbits finalization, adapter and drive manufacturers used a bridge chip to convert existing PATA designs for use with the SATA interface. Bridged drives have a SATA connector, may include either or both kinds of power connectors, and, in general, perform identically to their native SATA equivalents. However, most bridged drives lack support for some SATA specific features such as NCQ. Native SATA products quickly took over the bridged products with the introduction of the second generation of SATA drives. As of April 2. SATA hard disk drives could transfer data at maximum not average rates of up to 1. MBs,1. 4 which is beyond the capabilities of the older PATA1. SATA 1. 5 Gbits. SATA revision 2. Gbits, 3. MBs, Serial ATA 3. SATA revision 2. 0 was released in April 2. Native Command Queuing NCQ. It is backward compatible with SATA 1. Gbits. 1. 5Second generation SATA interfaces run with a native transfer rate of 3. Gbits that, when accounted for the 8b1. Gbits 3. 00 MBs. The theoretical burst throughput of the SATA revision 2. SATA 3 Gbits, doubles the throughput of SATA revision 1. All SATA data cables meeting the SATA spec are rated for 3. Gbits and handle modern mechanical drives without any loss of sustained and burst data transfer performance. However, high performance flash based drives can exceed the SATA 3 Gbits transfer rate this is addressed with the SATA 6 Gbits interoperability standard. SATA revision 2. 5editAnnounced in August 2. SATA revision 2. 5 consolidated the specification to a single document. SATA revision 2. 6editThis section needs expansion. You can help by adding to it. November 2. Announced in February 2. Tv On Computer Software on this page. SATA revision 2. 6 introduced the following features 1. SATA revision 3. 0 6 Gbits, 6. MBs, Serial ATA 6. Serial ATA International Organization SATA IO presented the draft specification of SATA 6 Gbits physical layer in July 2. August 1. 8, 2. 00. The full 3. 0 standard was released on May 2. Third generation SATA interfaces run with a native transfer rate of 6. Gbits taking 8b1. Gbits 6. 00 MBs. The theoretical burst throughput of SATA 6. Gbits is double that of SATA revision 2. It is backward compatible with SATA 3 Gbits.
