More importantly, what are the specs of your computer?
At least four internal HDDs would be recommended.
My computer specs:
Processor: Intel(R) Core i7 CPU X980 @3.33GHz 2.66GHz
RAM: 24 GB
64-bit Operating System
Video Card NVIDIA G Force GTX 680
I have space for 8 internal drives. I was thinking I should have at least a 4TB SSD (2TB plus 2TB volume) and an external 4TB HD Back-up
