sd card corruption

[WizardStan]

Linux-SWAT, Prometheus and WizardStan have all repeated how their class 4 cards are fast enough. And yet, I'm not the only one who has noticed a significant performance increase when using faster rated media.

Maybe I say that because it's supported by evidence? Even the class 4s are hitting 16MB/s reads, excepting the one sandisk which still gets 12MB/s. The chart on writes is similar, with most cards including the class 4s and 6s reaching at least 10MB/s.
