ReadAhead is a technique which should improve disk performance. When small part of the file is read, Linux reads much more data and stores it in internal cache.
To print readahead for disk /dev/hda, use
blockdev --getra /dev/hda
It is printed in 512-bytes blocks
To modify ReadAhead, use
blockdev --setra 1024 /dev/hda
