Check Newegg. 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. >Second, to maximize 'depth' of backups you should use a 'Tower of >Hanoi'-like backup system. Good advice, thanks! -- /Sorin
