The entire point of redis's VM layer is to serve data sets larger than ram when the request distribution is such not everything need be memory resident (I believe this is sometimes referred to as the 1:10 problem in the redis community). While ram is far cheaper than it once was, there still are substantial savings in reducing your resident set requirements from TBs to just hundreds of GBs.
