Separate drives, gaming rig

[gasdoctor]

Hi,
Bit of advice needed as Im not too hot on this subject.

Is there much advantage to having the OS on a small separate drive and my games, apps on another?

I'm gonna build a NAS device, so that will store everything, leaving my rig quit light.

Just wonder if two drives would be better than one with a partition.

what's peoples thoughts?

(then suggest some drives)

Cheers.
