About 130 to 140 GB with 512Kbps
Thats great. Yes, I agree that Bluray/HD stuff will take up that much space. You must be having massive Hard disks to store them.
I do 40-50GB in a month using my 256kbps UL.
By the way, I didn't find pleasant experience with 256kbps UL, while using Video/Voice chat.
Does it work well without any issues on 512kbps UL ?
