This is indeed the current suggested practice. The problem with a mem
cache is that is uses the memory POORLY. Basically, it pre-builds a
set of cache chunks and fills them in as it would a disk chunk.
However, if you don't use all the 'space' in a chunk, that space is
effectively wasted in the memory cache, where on the disk cache it can
be used elsewhere.
So, yes, disk-cache on a ram-disk will be more efficient than a
memcache.
