These are the only memory cards I use. I never have to wait on the buffer and they are rugged and hold up very well. I have them in sizes ranging from 512GB to 32GB. I use (1) 512GB in slot 1 on wildlife camera bodies and a 256GB or 128GB in slot 2. For landscape, night sky, macro, or street photography camera bodies I have a 64GB in slot 1 and a 32GB in slot 2. Unless I am doing a very long timelapse sequence, then I will get a bigger memory card.
