When viewed side by side, it is easier to tell the difference between as SAS and a SATA device. This latter configuration leads to confusion with the SAS connector, which looks similar to the joined SATA connector. The SATA data and power cables may be installed independently or as a coupled connector (as shown). The SATA power connector may be provided directly from the power supply, or via a Molex or mini-Molex cable converter. The SATA power connector has 15 pins, and also terminates with an L-notched connector. The seven pin SATA data cable terminates with an L-notched connector with which all CompTIA A+ candidates must be familiar. The SAS connection merges power and data into a single edge connected cable. The SATA connection requires two connectors, one for data and one for power. Both SATA and SAS facilitate device hot plugging (although caution should be exercised to prevent static discharge).īoth SATA and SAS use the same pinout for data and power connections, although the connectors themselves are slightly different. There is no need to manually assign device IDs or terminate connections as with the Parallel SCSI solution. SATA and SAS use full-duplex, switched serial, point-to-point connections.

You can find a historical description of SCSI, ATA, SATA, and SAS on Webopedia from which you can research further differences, although the details are less relevant to exam candidates.

SAS stands for Serial Attached SCSI, a replacement for the older Parallel Small Computer System Interface technology. SATA is a form of Integrated Drive Electronics, which identifies the controller as being integrated with the device and requires only a simplified circuit on the motherboard. SATA stands for Serial Advanced Technology Adapter and is a connection type used for a wide array of personal computer devices.

While the question is somewhat esoteric and unlikely to be found on the CompTIA exam, it is worthy of an explanation and perhaps a picture or two just in case you run into a SAS connector while supporting personal computer systems.

During a recent Windows 10 course one of our instructors was asked about the difference between a SATA and a SAS connector. The CompTIA A+ 220-901 exam typically asks candidates to identify connectors, cables, and other system components using photographic exhibits.
