Is hyperduo function similar to cache on a standard hard drive or a sshd like a firecuda. i.e. bits or whole files?

Want ram to preload bits not hold full files... Thinking of streaming application of large files.

look like sshd. it cache file

how big and how many are the files? if they are too many/big, won't be caching them all.
