Well... Stress test still running on reputable brand with no PB, after 6 or 7h. During this stressing session, we found a few broken SD, from another reputable brand. Not all cards, though, but enough to put some confusion... ;-) Something else added to the confusion, was an article on a Linux block layer issue... OK. Now, at least, we have a "stressing" tool and a stack of RPI in case of doubt on SD :-) By the way, is there any well known bench mark tool for SD, on CentOS or OpenSource ?
