It is a class 10 card. The camera transfers pics via WiFi.

I try to transfer the pics to my comp and backup drive once a month. I put them in monthly folders. I never delete them from the camera because I gots plenty of room. Since I'm not a porn photographer I'm not worried about losing it and somebody getting my valuable shots.
I've got digital pics going back to 1997 taken with a Kodak DC120. Now that's an ancient camera. Got pics of the kids when they were babbies and toddlers.
