I have a LOT of hd stuff, 1080p and 720p A 1080p Movie can take up from 8 gb to 20 gb depending on encoding. I'm a digital packrack. I've replaced cable with a ZFS backed network of htpcs running xbmc on the ionitx boards. Each htpc uses about 30 watts of power peak and does 1080p without a problem. each box also has a dvd player in it if we want to watch an old dvd. I also have rtorrent running using rss to grab all the new shows, which normally show up a few minutes to an hour after they air. I've got them set to automatically sort and placed in the correct spot. It's easy to fill up many tb's of space with whole seasons of 720p and 1080p TV, and hundreds of movies. Using xbmc and some of the wonderful skins you can make some amazing alternatives to cable. I just got tired of channel surfing. Also, i use my multi TB system to run rsync backups on all the computers i care about. Snapshots allow me to return to any day.... I'm also saving right now to build a backup system to have a second copy of the stuff i don't want to lose. I also try not to go over 50-70% full. when i get that full i start looking at ways to upgrade. I started with linux and an xfs based system on a single tb drive and just kept expanding it...when i found out about ZFS i knew that was the way to go. I can't stand to delete the stuff i have unless i find better copies...so as long as there is new stuff coming out, i'll probably keep expanding my system.
