Seagate Barracuda, Western Digital (Green) and Western Digital (Back)

Hi there lElprince,

It really depends on what is the purpose of the drive. Regarding the two WD models that you have mentioned, I would say that WD Black is designed to be a primary drive with good performance. It is a premium product that comes with 5 years of limited warranty. In case you need a secondary storage drive, WD Green may be the better option as it has power efficient characteristics and runs quiet.

Hope this clarified the things a bit,
