My systems need to write something every minute. They're generally monitoring various sensors.
Can't the writing be delayed?
Perhaps, but at the risk of losing the data.
Linux never crashes :-p

It totally ruins the idea of a neat and tiny device being hidden away in a corner. The ARM board is only 50x50, the power supply is already bigger than the board :-)
These tiny computers can probably run directly from a battery, that could be charged on standby.
The project is growing :-)
Or... have a huge capacitor, and on power failure issue an emergency write everything order, then halt.
Yes, I have actually wondered about that, using a supercap.
