Is the $10 worth the risk of it dieing with your data? It'll probably be fine, I mean even the SanDisk might die.~$10 difference, so probably not worth the risk.
Soooooo I'll say "it'll probably be okay". If it meant the difference the size card I was going to buy I guess I might take the risk and back up often. (But you really gotta do it, as you should be doing it anyway)
