This review is from: SanDisk 32GB Ultra SDHC UHS-I Card - Class 10 30MB/s
High capacity, sandisk warranty
Using this card, my Canon T3i will randomly stop taking video. This is a sign that the write speeds are highly inconsistent!
Testing the card with multiple programs (including error checking software that fills the card up), it only starts writing about 10-11MB/s until after about 8 seconds it rapidly declines to an average of 5.5MB/s. I returned one card hoping that it was a faulty card, but the replacement has the same exact issue (first one ordered online, then did an in-store swapout).
I don't know if there's a faulty batch of these cards out there, but if it can't sustain 10MB/s write speeds, it is NOT a class 10 card!
