- When you are using a laptop (journalling FS canes battery life)
Depends if you have a good nvram device to put the journal in (ie not PC BIOS settings area). Does anyone know which laptops do? In any case, I suspect that setting journal options appropriately for a laptop would optimise the disk writes and save battery life... but I can't find good figures for it on ext3.
I recall that by design ext3 polls the disk every 5 seconds (possibly longer) but not in any way that you could shutdown the disk effectivly for any length of time to actually save power.
