Serial Advanced Technology Attachment
Serial Advanced Technology Attachment
Serial Advanced Technology Attachment (SATA) is a computer bus interface connecting host bus adapters to mass storage devices such as hard disk drives and optical drives. SATA transfers data serially rather than in parallel as older ATA standards do.
What does Serial Advanced Technology Attachment mean?
Serial Advanced Technology Attachment (SATA) defines a standard for connecting Host bus adapters to mass storage devices, such as hard disk drives and optical disc drives. SATA provides a serial, point-to-point interface that is used to transmit data between the host and the Storage Device. The SATA interface is designed to be low cost and easy to implement, while also providing high performance.
SATA is an important interface in technology today because it is used to connect a wide variety of storage devices to computers. SATA drives are used in desktop computers, laptops, servers, and External Storage enclosures. SATA is also used in embedded systems, such as automotive infotainment systems and point-of-sale terminals.
SATA has a number of advantages over parallel ATA (PATA), the previous standard for connecting storage devices. SATA is faster than PATA, and it provides better performance for both reads and writes. SATA is also more efficient than PATA, and it uses less power. In addition, SATA is more compact than PATA, which makes it easier to design and build smaller devices.
Applications
SATA is used to connect a wide variety of storage devices to computers, including:
- Hard disk drives
- Optical disc drives
- Solid-state drives
- Hybrid drives
- External storage enclosures
SATA is also used in embedded systems, such as:
- Automotive infotainment systems
- Point-of-sale terminals
- Industrial control systems
SATA is an important interface in technology today because it provides a high-performance, low-cost, and easy-to-implement way to connect storage devices to computers. SATA is used in a wide variety of applications, from desktop computers to embedded systems.
History
SATA was developed by a consortium of companies, including Intel, Maxtor, Seagate, and Western Digital. The first SATA specification was released in 2003. SATA has since been updated several times, with the latest revision being released in 2019.
The first SATA specification, SATA 1.0, supported a data transfer rate of 1.5 Gbps. SATA 2.0, released in 2004, supported a data transfer rate of 3.0 Gbps. SATA 3.0, released in 2009, supported a data transfer rate of 6.0 Gbps. SATA 3.2, released in 2019, supported a data transfer rate of 16.0 Gbps.
SATA is a widely adopted interface, and it is used in a wide variety of applications. SATA is a mature technology, and it is likely to continue to be used for many years to come.
