You could use "relatime", basically this gives you the performance 
benefits of "noatime", but still updates the atime field when the it can 
be done with no performance overhead (such as when the block is being 
updated anyway)... and when the "atime" value is more than a preset time 
old, RHEL defaults to 1 day.

This should be granular enough for what you want.
