What is the SATA chipset?
SATA chipset, otherwise known as serial advanced technological supplements (ATA), is a popular interface used on desktop and notebook computers. The SATA interface connects a computer motherboard with a mass storage hardware such as optical units and hard drives. The chipset transmits data using a high -speed cable with two wires.
The dynamic cabling system connects the SATA chipset with the motherboard and hard disk. Users can connect 2.5 inches (about 63.5 mm) and 3.5 inches (about 88.9 mm) of hard drives using the same cable. Each SATA drive must be connected to the power and transmission cable. SATA cables differ in length, but can be up to 3.3 feet (about 1 m). A small shape factor and a reduced cable material cause SATA chipset ideal for laptops and small desktop computers.
SATA cable has a direct connection to a storage device, often referred to as Point-to-Point infrastructure. Data transfer cable contains seven pins and coding notch; FemaleE pins serve as data connectors and three other are ground pins. Data transmission is encoded using a logical algorithm called "8b/10B", which combines a clock signal with a balanced DC data current.
SATA cabling attempts to prevent noise, which is one of the most common data transfer problems through high -speed electrical connection. Unlike the older SATA chipsets, the benefits of differential signaling to reduce distortion during transmission. It turned out that it is an improvement in older PATA connection, which used signaling with one end.
SATA chipset replaces parallel ATA (heel) chipset commonly used on older computers. SATA provides numerous advantages over the heel, including the ability to replace hot, reduced production costs, faster transfer rates and fewer cables. SATA cables need only two wires while the chipsets of the heel youThey also live 16. SATA CA also contains seven wires, instead of 80 used in the heel systems.
Chipsets SATA also enables users to take advantage of swaping hot and native queries on commands (NCQ) via the Advanced host Controller (AHCI). The motherboard and the operating system must support AHCI to work properly. Older operating systems and computers do not support AHCI and force the SATA chipset to work in the ATA emulation environment. SATA chipsets are not backward compatible with old heel hardware. Since there are many PATA systems today, there are various SATA adapters that facilitate the data transmission process.
SATA chipset requires a power supply connector in the shape of a wafer that is significantly wider than the previous ATA power supply. The wide shape factor reduces the chances of randomly inserting the cable into the wrong "place" on the motherboard. Other pins are required because the connector also supports 3.3 Volts Standard 5-V and 12-VoltStandard. The other pins on the connector serve as a hotplug and a "hit spinup".
Since its entry into the computer market, there have been three revisions of the SATA chipset. Revision 1.0 offered non -coded transmission measures of up to 1.5 gigabites per second (GBPS), with actual rates on average 143 megabytes per second (MBPS). Revision 2 SATA chipsets have a native 3.0 Gbps transmission rate, with actual rates on average 284 Mbps.
The latest revision of the SATA standard increased maximum permeability to 6 Gbps when used in power units (SSD). The third revision optimizes the SATA chipset for multimedia and video streaming through the "quality of services" improvements. The third revision requires additional energy to support higher transfer rates and is compatible with previous SATA revisions.
