Hi, I'm a musician using my pc to record/compose etc. I'm using a RAID 0 setup for my OS programs etc, but I wanted a backup solution for storing all my recorded audio. I was thinking of 2 internal hard drives in RAID 1. The question is whether to fit 2 3.5" drives or 2 2.5" laptop drives. It's about noise levels more than speed. Can anybody give any help or critisism on this idea? Many thanks.
