Whoop dedup!



I've seen this before. They've basically made a really huge version of the game Old Maid.

What I really want to know is how much hard drive space people would really need if this were effective in all cases. How many terabytes of hard drive space would be saved if you only had to have one instance of Windows XP in the entire world? You could have thousands of porn videos on a 128MB hard drive.

Although...what happens if redundancy information is the same as someone else's? Do we need a service to check for redundancy in the redundancy?
