Last time I purchased my a119s I had purchased a lexar 633x 64gb card along with it. I have never had problems with corruption or sd card not saving. The card is about 2 going on 3 years old now. I just purchased an a129 duo and was looking at possibly getting another sd card. Should I keep using this til it dies? Is there anything better? More reliable? I'd like to know. I'd likely purchase from some other genuine place as Amazon is flakey now when it comes to buying genuine products.
