If this happens to be a linux server you could do this by echo 8192 > /sys/block/md0/queue/readahead_kb for a software raid. If it's a hardware raid, use the device name of that instead of md0. (please check the exact file names and path since I can't look at one right now) My experience was that throughput generally went up a lot, and also I think it should stabilize concurrent read/write. 8192 equals 8MBytes; in my tests I've seen the best value to be either 4 or 8MB, depending on the number of and type of the disks in use. Too high values and my throughput values would drop.
