The smallest SD Card you can get that is fast enough for modern camera, drones, etc is 8GB, maybe 4. I think I saw a 4 at Walmart. But, honestly, SD memory is cheapest per GB between 16&32 GB. That's the best value. But even an 8 would be way better than a 2. If the device you are using is old and had a 2 that died, don't worry. It should at least go to 8. And even if it doesn't recognize all 8, the 2-4 it does will be used and you can use the rest of the space on a diff device. Staples in Dickson has some SD and Flash drives on a good sale this wkend. Worth checking out.
No, I haven't seen them in that small increment. I'll check today when I arrive and let you know 100%
