Is there a difference between SATA hard disk and WD hard disk? What is the difference? (The more detailed, the better)

The two concepts you are talking about are completely different.

SATA is a working type of hard disk, commonly called serial hard disk. To put it simply, it is this kind of hard disk that supports hot plug, the transmission speed is faster than that of the old parallel hard disk, and it can automatically correct errors when encountering errors, and its drive is simpler than that of the old parallel hard disk!
