StorageMojo » Our changing file workloads Interesting study results. Some of the things that fascinate me:
* Files rarely re-opened. Over 66% are re-opened once and 95% fewer than 5 times. Over 60% of file re-opens are within a minute of the first open.
* over 90% of the active storage was untouched during the study
hmm, providing a backup service has to be profitable given this info.
