If you wnant to power-save more on disk access, just add noatime to the 
mount options in /etc/fstab

Who need accesstime updated on any file? nobody, nothing except the very 
specific use bye a news server.

Adding noatime to flash drives wil save their life time as well.

Why is it not the default ?
