I have a long running positive history with SanDisk flash products. Both flash drives purchased are operating normally in the cameras I needed additional storage for. That said here are my observations. The warranty is stupid short (2 years), how is that supposed to compete or instill confidence in a product that’s writing life is advertised for longer than the warranty? Objectively, the fetch times are significantly longer while recording than the competition. We are talking about horse and buggy here for the same operation. Yes, the media was formatted in the camera. Anyway, my two cents. Overall, I hope they live longer than advertised, sorry warranty.
