Well the harddrive can be however big you want it to be. If you just want a certain year I can tell you how big of drive to get. I dont have every show ever YET....but I'm shooting for it, right now 95, 96, 97 (will fit on 1x250gb) are basically complete and 94 is dam close, but 94 is closer to 100gig by itself cuz that was the year with the most shows. I've got other years that are done but it just takes time to organize them into my archival format. And once and a while when going back files get corrupted, and i need to go back and track them down, luckly the week4paug team ususually comes to my rescue. All in all i'm thinking all phish shows will take close to 1.2tb.
If you want the best, IMO this is as good as it gets. I've spent countless hours trying to standardize, and organize...cuz i'm an ubergeek I guess. But i messed around with this stuff for years and finally about a year or two ago I decided this is how I needed it to be, and now its finally getting closer to being finished. And if I B&P this out to enough people, we could start doing a monster torrent of an entire tour/year/whatever.
