-> can handle 5 blocks -> what fishy is going on that it freezes with more? -> is this card useful at all if it behaves like this?
Depends. How do you know that it freezes? Sometimes these tests can take a *very* long time. Do you see any messages in 'dmesg'?
If the card is a fake one, it's possible that it's already hitting some broken erase blocks.
