I have uploaded as much as 132 GB and downloaded 123 GB since I used µTorrent. If I remember correctly I have uploaded as much as 130 GB in Azureus and download 190 GB before my PC was wiped out. Then I have uploaded another 60 GB and downloaded 45 GB in Azureus again. In total I have seeded 322 GB and leeched 358 GB, which will easily fill up my hard drive. x_x Thanks to DVD-/+R doing backups is a relief.
