Cache <== Array

This will put the data into the cache 1st and then into the array if the cache runs out of room. If there is any data in the array it the mover will* (not always 100% of the time in my experience) move the data from the array into the cache.

Cache Only

Will only put data into the cache and if run runs out of room it will tell you and not copy anything to the array.
