I haven't got a budget really. Today I asked for a new group-printer today and 
the boss looked pained... 8-}

I opted for the proven 500GB-sized disks and got more of those instead. I've 
had a handful of 750GB-drives die on me recently. Somehow it feels the 
technology isn't quite there yet for the bigger drive-sizes. Anybody remember 
the IBM Deskstars in the early 00's...?

Also, my experience is the more smaller disks you have, the faster they get. 
Less to write to each I guess.

Good advice, thanks!
