Indeed, my problem with eprom systems and this is based on my experience with automobiles, once the internal memory gets corrupted or fails, you are totally screwed and need to change the entire module. That's why in this specific case, I see it as a smart idea to use even a serviceable and replaceable storage system which will not incur in the entire replacement of the board or system. Why bother in changing and throwing away a perfectly good system when only one component failed? Remove the SD card and put a new one and you are gold, I see that as pretty clever.
My point was that if it can be removed and replaced then it's not tamper resistant. In this case it's not a matter of cost (customer pays if failure not their fault), but a matter of preserving information (to determine fault). |
