I've been using F3 (http://oss.digirati.com.br/f3/ http://oss.digirati.com.br/f3/) to test new SD cards. Installable via homebrew and seems to work quite well

- randkyp 9y agoYes. I just run f3probe for a quick capacity & speed test and then run a single-pass, random data badblocks test just to be sure. If there are any 'bad' sectors, I just pass the badblocks output to mkfs. Be careful with your choice of card reader/adapter though--some starts to get too hot and end up breaking the card under heavy testing!
