This is the SD card from my main camera. In fact the actual SD card is a micro SD and almost too small to be photographed, and this one is an adapter to bring it back up to a reasonable size. The thumbnail-sized fingernail-sized card itself fits about 4000 high-resolution RAW photos, which is pretty amazing. I remember floppy disks, and having to swap them out halfway through installing an application or running a game, because you couldn’t fit all of it onto one disk.

Less amazing is the write protection tab, which keeps catching on the the card slot on my computer when I insert the card, and moving to the ON position against my wishes. It was getting to the point where it took me ten tries to get my photos imported and deleted from the card.

I bought a new card of a different brand, and it works much better for me. The write protection tab is much harder to move. Weird, how two makes of the same thing, that is so strictly standardized when it comes to size and shape and performance and protocols, can still differ so much in such a tangible way.
