Yes, but the OS has a lot more memory to cache the reads for you, so you
should be relying more heavily on it in cases like this where the card has
a relatively small amount of memory. The main benefit for having a
caching controller is fsync acceleration, the reads should pass right
through the controller's cache and then stay in system RAM afterwards if
they're needed again.
