>Currently I have a 1Tb drive in my laptop. With all the various applications (Office, VS, VFP, SQL (serveral types), much more), I am only using 18% of it. But I do not do Photos or Music, so space is not a problem to me. My local backup drive is a 64meg USB stick, using less then 30%.

I do. My playlist is over 20000 titles, and I've made more than 100000 photos, perhaps close to 200k as I keep shooting. And even some family videos, though not much, perhaps 30 minutes a year. And I still haven't used half of my 3T in harddisks - and all my databases, virtual machines etc are in that space too.
