SATA is a serial interface that is used for connecting disk storage devices to the computer system. This protocol is less expensive and has a higher data rate than the PATA protocol used previously. SATA cables are used to physically link the storage devices to the memory controller on the motherboard. It is the controller that is tasked with managing the data flow to and from mass storage drives.
It is a straightforward process to install SATA cables on the system to link it to the storage media. However, you have to be careful not to damage the cables and use only the recommended method to achieve it. You also need to install the appropriate cable on the right equipment. That is particularly important as there may be different ratings for SATA power cable. For instance, the SATA cable for Optiplex, might not work in other devices. SATA cables for the ProLiant server series also exist, and the list goes on and on.
You will not have any problems if you buy the appropriate cable for your equipment. Just follow the provided procedure to attach storage devices to the system, and it should work without any problems.
We have SATA power cables and SATA data cables. Each one of these has specific uses and should not be swapped. SATA power cable is usually larger and has a 15-pin connector. Out of the 15 pins, three of these pins supply power at 3.3V, 5V, and 12V, respectively. Some versions have a 4-pin connector, but the 15-pin one is the most common.
SATA data cables have 7 pins for achieving data transmission from the storage devices to the host computer. These hot-plug cables are typically smaller to give more space in the chassis for effective cooling.
Apart from the differential signaling that is a salient feature of SATA protocol, they also have error detection and correction capability. That ensures high data integrity that mission-critical applications require. SATA cables are also energy-efficient and reduce cable-to-cable crosstalk.
