However, other things being equal, full-size SD cards are generally faster than small ones. I assumed most of us needed different sizes, so it's handy if all your devices use the microSD format. Obviously, you can't fit an SD card into a miniSD or microSD slot. You can use a miniSD or microSD card in an SD card slot by plugging it into an SD-sized adapter, and some mini/micro cards are sold with them. This resulted in the miniSD format, measuring 21.5 x 20mm, and then microSD cards, measuring 11 x 15mm. These are still common in digital cameras, audio recorders and similar products. The original format started with cards measuring 32 x 24mm, which was very small for the time.

For this sort of application, you'll probably need a fast card. If you want to shoot high-definition videos, keeping up can be a challenge. However, if you want to shoot a rapid sequence of photos, the card has to be fast enough to keep up. The result is the chaos we enjoy today.įor standard applications like single-shot compact cameras, it doesn't matter which class of SD card you buy, as long as it's compatible.

I was shopping online for some new microSD cards and got thoroughly confused by the different classes/speeds.
