To buy WD Gold or what? How do the different drives compare?


I am looking for information on what kind of stability and durability features, such as vibration cancellation are there in which drives? I know that the bare minimum is the Blue and Green drives, and that the enterprise drives have much more features.

I wish to buy some medium capacity drives, i.e. 4 TB to 6 TB, but I’m confused about whether Ultrastar DC HC600, HC500, HC300 or HA200 are better or worse equipped and which one should I prefer.

Also, what do the Red and Red Pro drives have, compared to these? The Red Pro is not an enterprise drive, as far as I know, but what is it missing then?
