SD cards compatibility.

I recently bought a Nikon d3100 dslr camera that uses sd cards. I needed to know which sd cards I needed because this camera does video as well as stills. I thought this info would be helpful to my readers because not all card reading devices would work and I'm glad to know that before I upgrade any cards or readers because of a sale price! I also looked in my camera manual and learned I can use all three types. I went to Nikon on line to get this factory manual. Learning should never stop!

I found this great information online about sd cards at https://www.sdcard.org/consumers/compatibility/
