What about the situation where the primary storage is a device which has a limited number of write-cycles. That's just the sort of application where you might be archiving data to secondary or tertiary storage, and it would be a big advantage to save on writes. If a file is read every ten minutes, we could just update the atime once an hour. That would save five writes an hour. John.
