Hi, is it advisable to NOT enable log option for FFSv2 that resides on SD card due to flash memory wearing out in those regions, or does it make no practical difference because of built-in wear levelling?
How long's a piece of string? Wear levelling just evens out the wear... surprise. It doesn't account for the overall wear. I read a document many years ago, where a 4kb cluster size for a 1 GB SD and 4kb writes per N seconds (where N was below 10, can't recall), and the estimated life of the SD card was 80 years. So, go ahead and enable logging. At worst you probably shorten its life by a few years. Of course, this all depends on the read/writing you're doing to the SD card. YMMV.
