Serial ATA - Wikipedia.Serial ATA (SATA, abbreviated from Serial AT Attachment)[2] 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. . MegaRAID SAS 9341-8i Add robust data protection to small and medium business (SMB) applications like email and file servers. Memtest86+ is a new and enhanced memory test application based on a version of memtest86 - see here for details. As well as testing memory, it can also identify. I/O 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.[3]Prior to SATA's introduction in 2. PATA was simply known as ATA. The "AT Attachment" (ATA) name originated after the 1. IBM Personal Computer AT, more commonly known as the IBM AT.[5] The IBM AT’s controller interface became a de facto industry interface for the inclusion of hard disks. AT” was IBM’s 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.[6]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; SATA's market share in the desktop PC market was 9. Edit Article wiki How to Install Windows XP. Three Parts: Setup Installation Completion Community Q&A. Windows XP is one of Microsoft’s most popular operating. PATA has mostly been replaced by SATA for any use; with PATA in declining use in industrial and embedded applications that use Compact.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.[8][9]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 will try to use the terminology and specifications of SATA- IO. Features[edit]. SATA 6 Gbit/s controller, a PCI Express ×1 card with Marvell chipset. Hotplug[edit]The 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.[1]Advanced Host Controller Interface[edit]Advanced 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 "IDE[b] 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 SATA's 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 Intel's.[1. Revisions[edit]SATA 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 Gbit/s". SATA revision 1. Gbit/s, 1. 50 MB/s, Serial ATA- 1. Revision 1. 0a[2] was released on January 7, 2. First- generation SATA interfaces, now known as SATA 1. Gbit/s, communicate at a rate of 1. Gbit/s,[c] and do not support Native Command Queuing (NCQ). Taking 8b/1. 0b encoding overhead into account, they have an actual uncoded transfer rate of 1. Gbit/s (1. 50 MB/s). The theoretical burst throughput of SATA 1. Gbit/s is similar to that of PATA/1. SATA devices offer enhancements such as NCQ, which improve performance in a multitasking environment. During the initial period after SATA 1. Gbit/s 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.[1. 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.[citation needed]As of April 2. SATA hard disk drives could transfer data at maximum (not average) rates of up to 1. MB/s,[1. 4] which is beyond the capabilities of the older PATA/1. SATA 1. 5 Gbit/s. SATA revision 2. 0 (3 Gbit/s, 3. MB/s, Serial ATA- 3. SATA revision 2. 0 was released in April 2. Native Command Queuing (NCQ). It is backward compatible with SATA 1. Gbit/s.[1. 5]Second- generation SATA interfaces run with a native transfer rate of 3. Gbit/s that, when accounted for the 8b/1. Gbit/s (3. 00 MB/s). The theoretical burst throughput of the SATA revision 2. SATA 3 Gbit/s, doubles the throughput of SATA revision 1. All SATA data cables meeting the SATA spec are rated for 3. Gbit/s 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 Gbit/s transfer rate; this is addressed with the SATA 6 Gbit/s interoperability standard. SATA revision 3. 0 (6 Gbit/s, 6.MB/s, Serial ATA- 6. here. Serial ATA International Organization (SATA- IO) presented the draft specification of SATA 6 Gbit/s 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. Gbit/s; taking 8b/1. Gbit/s (6. 00 MB/s). The theoretical burst throughput of SATA 6. Gbit/s is double that of SATA revision 2. It is backward compatible with SATA 3 Gbit/s.[1. The SATA 3. 0 specification contains the following changes: 6 Gbit/s for scalable performance. Continued compatibility with SAS, including SAS 6 Gbit/s, as per "a SAS domain may support attachment to and control of unmodified SATA devices connected directly into the SAS domain using the Serial ATA Tunneled Protocol (STP)" from the SATA Revision 3. Gold specification. Isochronous Native Command Queuing (NCQ) streaming command to enable isochronous quality of service data transfers for streaming digital content applications. An NCQ management feature that helps optimize performance by enabling host processing and management of outstanding NCQ commands. Improved power management capabilities. A small low insertion force (LIF) connector for more compact 1. A 7 mm optical disk drive profile for the slimline SATA connector (in addition to the existing 1. Alignment with the INCITS ATA8- ACS standard. In general, the enhancements are aimed at improving quality of service for video streaming and high- priority interrupts. In addition, the standard continues to support distances up to one meter. The newer speeds may require higher power consumption for supporting chips, though improved process technologies and power management techniques may mitigate this. Colour Confidence Print Profiler Software . The later specification can use existing SATA cables and connectors, though it was reported in 2.
