If you're running a raspberry pi type machine with storage on an SD card or similar. It's too easy to kill them with many writes. Also on a dedicated systems where you have full control of the stack, the apps, and have resource limits in place anyway. If you know your embedded system will never need more than X GB, you can use it as resource limit of last resort. (And hopefully let the watchdog reboot it after the required app fails to check in)
