SanDisk is the card most commonly provided by Autel. It is also a very reliable card. There are cards that read/write faster than others, so look at the specs when you purchase a card. Also, the computer or tablet, or phone you use to read the card can make a LOT of difference in how fast the card is read.
When a still photo is taken, then you have 22 Mpixels of picture written to the card. However, if you are taking video at 30 frames a second, then you have 22 Mpixels written to the card every 1/30th of a second - a ton of data. Likewise, reading that data also takes time, and takes more time with some computers, tablets, and phones.
