ext4 with journaling is a robust file system that avoids corruption after power loss. However, this doesn't seem to work for Raspberry Pi's. I assume this is because memory cards (and/or our memory card controller) are lying to the filesystem about when writes are actually committed to permanent storage.
Since journeling is not effective for Raspbian, why not turn it off to avoid the extra disk writes that it involves?
Is there any brand/model/whatever of memory card out there which does NOT lie to the filesystem and makes journaling robust?
