I've been using these cards for 2 weeks and their performance is exceptional. Bought the LEXAR because it was recommended to me by a friend and it's as fast as my SanDisc 128 SDXC card. Use it for RAW photos, 4k videos and 1080p slow motion scenes. There were no problems. Data transfer to my Mac was fine. Could be better but you get what you pay for.
