it seems that the raspberry pi burns out SD cards after some months in operation.
wear leveling is needed to prolong SD card life.
this underscores the first line of post #1 how much and how often ?
That's from people using SD like HD or as HD.
A different set of practices needs to be used like don't sort data files but instead write a file of sorted links into the data. Don't edit the original, save the changes or the whole edited file as a revision file instead. And last, get a USB HD.
