I bought one of these sixteen gigabyte SD cards to use with my Nikon camera that takes high resolution pictures. I needed a large enough card to hold pictures that are several megabytes big. This one has worked great. It can hold more than a thousand pictures, and they are always good quality. I have had other SD cards that ended up corrupting some of the pictures on them before I took them off onto my computer. But I have never had that problem with this card. It also transfers the pictures to my computer relatively quickly. On rare occasions, I have wanted to make sure pictures didn't accidentally get deleted off of this card, particularly when I let someone borrow it to take some pictures off of it. It has a manual switch that allows it to be locked for editing and prevents pictures from being modified or deleted. This has been very helpful in protecting them.
