What are the various type of SATA SSD Drive ?

Serial ATA (SATA) is a computer bus interface that connects host bus adapters to mass storage devices such as hard disk drives and optical drives. Serial ATA replaces the older AT Attachment standard (later referred to as Parallel ATA or PATA), offering several advantages over the older interface: reduced cable size and cost (seven conductors instead of 40), native hot swapping, faster data transfer through higher signalling rates, and more efficient transfer through an (optional) I/O queuing protocol.

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) used a 16-bit wide data bus with many additional support and control signals, all operating at much lower frequency. To ensure backward compatibility with legacy ATA software and applications, SATA uses the same basic ATA and ATAPI command-set as legacy ATA devices. SATA has replaced parallel ATA in consumer desktop and laptop computers, and has largely replaced PATA in new embedded applications. SATA’s market share in the desktop PC market was 99% in 2008.[2] PATA remains widely used in industrial and embedded applications that use CompactFlash storage, even though the new CFast standard is based on SATA.[3][4] Serial ATA industry compatibility specifications originate from The Serial ATA International Organization (aka SATA-IO). The SATA-IO group collaboratively creates, reviews, ratifies, and publishes the interoperability specifications, the test cases, and plug-fests. As with many other industry compatibility standards, the SATA content ownership is transferred to other industry bodies: primarily the INCITS T13 subcommittee ATA, the INCITS T10 subcommittee (SCSI), a subgroup of T10 responsible for Serial Attached SCSI (SAS). The complete specification from SATA-IO. The remainder of this article will try to use the terminology and specifications of SATA-IO. SATA is the name of the interface standard that allows a storage device, in this case an SSD, to communicate with a host system usually a PC or Laptop. It facilitates the functioning of all storage features, from basic input/output (or read/write) requests to advanced AHCI-enabled features like Native Command Queuing (NCQ), hot-swapping, power management, and RAID. SATA has gone through several revisions in its lifetime, boasting significant performance gains with each iteration. The SATA interface generation a PC is equipped with will have a direct impact on maximum SSD performance. For this reason, it is crucial to understand the difference between each SATA revision and the capabilities each SSD. SATA revision SATA 1.0 Released in 2003, SATA I, also known as SATA 1.5Gb/s, is the first generation of the SATA specification. As its name implies, it is able to communicate at up to 1.5Gb/s. This early revision does not support some modern storage features, such as Native Command Queuing. Maximum transfer rates are around 150MB/s, slightly better than the older PATA interface (also called UDMA 133) it replaces, which had a maximum speed of 133MB/s. SATA 2.0 SATA 2.0, also known as SATA 3Gb/s, is the second generation of the SATA specification. Released in 2004, it is capable of communicating at up to 300MB/s. This revision also introduces Native Command Queuing (NCQ), a feature that improves multitasking performance. SATA 2.0 is more than capable of handling the best hard drives on the market, but it is easily overwhelmed by the onslaught of Flash devices (SSDs) that are now popular. Computers purchased in 2005 or later are likely equipped with SATA 2.0 support. SATA 3.0 Released in 2009, SATA 3.0, also known as SATA 6Gb/s, is the third generation of the SATA specification. It is capable of communicating at up to 600MB/s, with overhead taken into account. In addition to its speed improvements, this revision also introduces NCQ management, improved power management features, and queued TRIM support (allowing TRIM commands to be queued with I/O requests, which was not possible on earlier implementations). While it is currently capable of supporting the massive speeds of today’s SSDs, it is already being outpaced as SSD technology advances. This is the standard that most modern SSDs are built to support, although they are backwards compatible with the earlier standards as well. mSATA Building upon the foundations of SATA 3.1, mSATA was designed to address the rising trend of continually shrinking Notebook computers. Smaller profile laptops require smaller SSDs, which in turn require smaller connectors. Notebooks that feature the mSATA interface are becoming more popular but still represent a relatively small portion of the overall market. Maximum transfer speeds are equivalent to the standard SATA 3.0 interface. SATA Express SATA Express is capable of speeds faster than SATA 6Gb/s thanks to its use of the PCI Express (PCIe) interface. Interface speeds may be increased to 8Gb/s or 16Gb/s (or perhaps even higher speeds later). Future motherboards will offer slots for both SATA Express and traditional SATA devices, and the SATA Express interface will be backward compatible with the standard SATA 3.0 interface.
