From http://www.mongodb.org/display/DOCS/Readahead
RAID on EC2: If you are following our Amazon EC2 guidelines, and running with multiple EBS volumes in a software RAID configuration, then the recommendation is to set the readahead to 0 on the volumes that make up the RAID array while setting the readahead to the value you want on the RAID volume itself.
