First, you need to know the related fs lay out data in disk. For
example, for fs like XFS which does delayed write, data is kept
adjacent as much as possible, thus read is faster since the disk head
almost doesn't need to jump.

Other thing to consider is the way Linux does readahead.... too much
readahead will waste your time reading unnecessary data.
