Personally, I really like having the drives. They've been reliable.
One thing to consider: 2010 version needed more Realtracks to work right. *Correct me if I'm wrong on version here*

Since then the new audio engine made it possible to reduce the Realtracks needed and save quite a bit of space. When I made the change early on it went from 80+ gig of tracks to 35 gig or so. So the new Realtracks allow getting more 'stuff' on the same space.
