![]() Almost all new power supplies now offer SATA connectors, but few Molex connectors because SATA has become the new standard. The SATA power connector has become the standard for powering everything powered by Molex connectors. There are also “slimline” and “micro” SATA power connectors for use with tablet computers and small form-factor devices, in addition to the standard SATA power connector shown here. It was by design since older PATA drives weren’t intended to be hot-swapped. ![]() With SATA drives, the power connector is specially designed to enable “hot-swappable” drives, which would have been immensely challenging with Molex connectors. PoE cables are used for transferring data between network devices. The SAS cable connects two hard drives to increase data transfer speeds. The SATA cable connects a hard drive to a computer or laptop via an internal port. They are the SATA, SAS, and power over Ethernet (PoE) cables. There are three types of power cables for hard drives. ![]() The wires are usually wrapped in insulation, though some cables are made of metal, like those used for home theater installations. It is typically composed of two wires, one of which carries voltage and the other, which takes ground. The hard drive power cable is a connector medium between the hard drive and the power source. Today, the hard drive is still used to store computer programs, digital data, and audio and video files.Īmong the components of a hard drive are the disk platters, read-write head, actuator arm, motor spindle, controller electronics, and firmware. The hard drive has been in use since the 1950s and was used to store computer programs, digital information, and other files. The hard drive HD or HDD is a non-versatile data storage device that stores data on a magnetic or optical disk. You can use this article to determine what type of hard drive power cable you need for your computer. The difference between them is that SATA is newer than IDE, which can transfer data more quickly. The two types of hard drive power cables are SATA and IDE. Which Type of Hard Drive Power Cable do I Need? What is a Hard Drive Power Cable?Ī hard drive power cable is a data cable that transfers power from a power supply to a hard drive. If you know more about power cables, please read this entire article until the end. It is done through a USB port on one end of the cable and a USB port on your computer at the other end. The cable is also responsible for transferring data between your computer and your external devices, such as printers or external storage devices. The power supply then converts the AC from the outlet into a DC that your computer system can use. The cable is usually connected to the power supply with a connector plug into an outlet. It provides the electricity needed to run the internal hard drive, storing data. A hard drive power cable is an essential component of a computer system.
