It depends on size of the data that you are storing and the block size. Here is a good primer on it: http://constantin.glez.de/blog/2011/07/zfs-dedupe-or-not-dedupe

As a quick estimate, about 5GB per 1TB or storage for SSD. However I believe that you would need even more RAM since only a 1/4 of the RAM will be used for the dedupe table with ZFS.

Thank you,

What's 'massive' in dollars these days?
