The image above shows an early model SATA hard disk drive with exposed internal components.
Newer SATA drives do not have the 4 pin molex power connector identified in the lower right area of the image. Early SATA models were often installed in computers with power supplies that featured only this type of device power connector.
PATA hard drives still use the four pin molex connector.
