A: A WD Gold drive combines the speed and performance (for a mechanical drive) of a WD Black and the reliability and continuous uptime of a WD Red. The WD Gold series is designed for data centers, so it has a long lifespan, fast reads and writes and is capable of being on and used 24/7. These are basically the best drives offered by WD.If you need performance you can go with Black, if you need NAS type reliability and uptime, you can go with Red. I went with Gold to get the best drive I could that provided both of those features.
