You dont use torrents everywhere do you now.
Maybe not but I cannot for the life of me remember when the last time was I had a corrupted download. Sure, a year of 4 back my RAM was broken, but then again so where the rar chunks, sfv files and everything else, so partitioning didn't help either.
The only time I can remember having to deal with it on a regular basis was back when I used a 56k, and connections were dropped regularly. Then again downloading a 720p release with that isn't viable anyway.
Cutting up big files is a thing of the past. Compression oftentimes costs you more time than it saves you. Time to move on. I don't even think for a second when downloading a 2GB demo from some site. The worst that can happen is a slow server and I have to wait a while.
