I'm not sure if this is relevant with Linux, but we have some Siemens MicroBox PLC's at work, they run Windows XP embedded IIRC. They have a compact flash drive and they have to protect the CF because Windows will try to read/write constantly as virtual memory and wear the CF cards out shortly. Then we have the problem that if we reboot, cycle power, or lose power, the settings are lost and we have to re-enter settings that have changed since last save with the write filter off.
Anyway, if Linux uses a drive as virtual memory, I would think it would have the potential to wear out a CF card fairly quickly, though their may already be work arounds for it.
