SATA Power Cables
When it comes to SATA power cables, 15-pole, power and data all have the same pitch of connector pins, but each has a different number of ways.
It is also worth noting that adaptors are generally available for PC power supplies that feature alternative types of power connectors.
SATA Cables for HDDs
In a PC setup, SATA cables can be used to connect the hard disk to the motherboard. Hard disks typically feature multiple inlet ports, at least one of which will be SATA compatible. The SATA cable is also responsible for supplying power to the hard disk so additional hard drive power cables may not be required.
SATA cables are beneficial as their shape has been specifically designed to help maximise airflow inside a CPU, saving space and boosting performance.
It is also worth noting that SATA cables can be used to connect external hard drives to a PC via the e-SATA input. Likewise, it may be possible to connect an external hard drive to a computer using a SATA to USB adapter if the particular hard drive supports USB input.
SATA Cables for Laptops
If you are using a laptop rather than a standard PC, the chances are that the laptop’s storage devices (HDDs, SSDs etc) are attached directly to the motherboard. As a result, a SATA cable should not be necessary. The motherboard and the breakout boards connected to the storage devices are joined with a thin, flat SATA cable specially designed for use in laptop assemblies.
