The fundamental SATA connector has two twisted pairs, three ground wires and 7 pins. It implements differential transmission with the clock frequencies varying from 1. The latter version of SATA also provides isochronous transmission characteristics to enable audio and video devices.
As mentioned above these AT attachments are the interface standard for the connection of storage devices hard disks, floppy drives and optical disks.
In PATA the length of the cable can be 18 inches at maximum It is regarded as a replacement of parallel interface ATA. It has been also successful in replacing PATA in most of the new embedded applications. Since its widespread introduction in , the SATA technology has already seen three generations.
It is the predominant disk interfaces technology in:. It predates the SATA-1 by more than a decade. The main cable may be a ribbon cable or round wires. Most of the time, a ribbon cable indicates you're using a PATA drive, and vice versa, but this isn't always the case. Count the pins or contacts on the cables. A PATA drive requires 39 or 40 holes in the data cable, and four pins on the power connection. A SATA drive requires two slot-type connectors, with seven contacts on the data connector and 15 contacts on the power connector.
Open the Windows Device Manager applet. It has a faster speed that helps to connect the devices quickly and hence it is very convenient to use. SATA provides an external interface that is very convenient to use. The size of the cable of SATA is small. It measures a 7-pin cable size. Both the ends are thin and flat, where one plug connects to the motherboard and the other to the secondary device. SATA has a master-slave arrangement.
SATA has more advantages as it has a small cable size, fast data transfer speed, etc.
