I'm running up to 18 tracks for a 3 piece band but we overdub bass and rhythm guitar.

each track has about 2-3 plugins.

I also run a plugin on the master track for mastering and widening.

I going to be recording other bands as a business so I may need more tracks than for what I'm doing.

Personally I think I could use up 4 gigs quite fast. (I work this thing pretty hard)
