Chaser Drone data storage required for video: per a youtube video, the measured eight minutes of recorded HD video (1280×720@20fps) occupies about 270MB on the camera’s micro SD card. Use the smallest 8Gb cards for multiple record sessions. These drones accept cards up to 32Gb, hence the FAT32 card format.
Chaser Drone Card Capacity
Cards in the FAT32 format are up to 32Gb.

Note, a carder reader is built into an Apple iMac, circa (c) 2011 running 4GB 1333 Mhz DDR3 and Mac OS 10.6.8. Look on the side of the monitor.
Micro Card Storage
Tiny micro sd cards are easily lost. They store well in the original snap lock clear plastic packages from Transcend, but even these are too small and can become lost. A shoe box works well for storage. The cards also can be kept inside the micro sd adapters, inside the card reader, and inside the card slot on the Chaser Drone.
