I was reading about them and I guess WD though they'd only be for server applications where size isn't as big of an issue so they weren't rushing larger capicty drives to the market. I think ~70ish Gigs will be enough for me. I plan to add a second larger storage drive later. I think I might be moving out soon too so I may rebuild an old machine for a file server so I can do external backups and the storage on this machine won't be such an issue.
