Well, atleast 80 GB.
Likely a lot more depending on how you model your data.

No, there is nothing by "Redis".

As indicated @Jan-Erik, "the data sets can't be larger than memory".

Should you read http://redis.io/topics/faq

Should that read http://redis.io/topics/faq
to clarify the issue (even if the reading does not solve your problem)-

   "I like Redis's high level operations and features, but I don't like that it takes everything in memory and I can't have a dataset larger the memory. Plans to change this?"

also,

and after, this post (already thinking of possible actions on your part),
