You can set the amount of caching being done whenever a read is going on, but that will use more RAM.

the card may be doing its own read ahead and buffering for you, I am not sure enough about the firmware on the PERC card.

I know that in some cases, especially in software RAID, that a read ahead will increase performance in some cases where you were to do some linear reads and such where you read say 4MB ahead of where the target read is, as that will likely be called and you gather the data more efficiently.
