What to look for in secondary/storage hard drive?

[Gupta_]

I bought Crucial MX300 275GB ssd for my main/programs hard drive. Now I need a second (and final) drive for storing other data like documents and videos and music. I know I should be getting a hdd for cheaper price/gb ratio but what about things like RPM and cache and such? And with Western Digital for example they have colors like blue/black/etc. Or if anyone can just recommend an exact product for under $100 and at least 1-2+ TB space for my build.

Thank you

Their really no reason to get anything more expensive than this. 7200 RPM cache is more or less just a gimmick all the modern drives will have about the same. When/If you need more space then just buy another drive.
