Thus, SATA connectors and cables are easier to fit in closed spaces and reduce obstructions to air flow cooling. However, cables up to 35 in are readily available. PATA ribbon cables, in comparison, connect one motherboard socket to one or two hard drives, carry either 40 or 80 wires, and are limited to 18 in length by the PATA specification. SATA cables can have lengths up to (3.3 ft.), and connect one motherboard socket to one hard drive. The SATA standard defines a data cable with seven conductors (three grounds and four active data lines in two pairs) and 8 mm wide wafer connectors on each end.

SATA is full duplex, differential, with a transmit pair and receive pair. The SATA cable results in a higher signaling rate, which corresponds to faster throughput of data. Data is moved one bit at a time between a SATA drive and its host, using a seven-pin data cable and 15-pin power cable. As its name suggests, a Serial ATA drive transfers data in serial fashion. PATA is Half Duplex, meaning transmit and receive cannot occur at the same time. The SATA SSD transport layer differs from PATA drives, in which data bits are delivered simultaneously across a 40/80 -pin-wide ribbon cable. Technical Differences Between SATA and PATA The redundant array of independent disk (RAID) mode supports both AHCI functions and RAID data protection features. Setting a SATA controller to Advanced Host Controller Interface (AHCI) offers higher performance than IDE mode, and enables features such as Hot Swapping on SATA drives. Putting SATA in IDE mode means the hard drive is recognized as a PATA device - a situation that provides better compatibility with older hardware, but comes with the tradeoff of lower performance. Serial ATA hard drives connect to a computerРІР‚в„ўs motherboard via SATA Controller hardware that manages the flow of data. SATA cables are thinner, more flexible and smaller than the ribbon cables required for conventional PATA hard drives. SATA SSD has several advantages over the Parallel PATA hard drives developed in the 1980s. It evolved from PATA, and shortly after its introduction replaced PATA in PCs and other systems.
