Just a couple things to note for future reference:
The
Air 2S records at most 120Mbps (likewise
Air 2S at 150Mbps, though usually 125Mbps when in H265/10-bit).
And for comparison, a
Mini 1 records at 40Mbps at most, with the
Mini 2 recording at 100Mbps (when shot at 4K).
The SD cards have speed classifiers on them, most of the common dirt cheapies are Class-10/U1 now, meaning they are rated to write continuously at 10MB/s, since there's 8 bits in a byte, that's 10*8 = 80mbps. It's the continuous write speed that you need to worry about, not what the manufacture advertises as ##MB/s as that's usually read speed, and usually only in bursts, not continuous.
A Class 10 (or V10 if it's labeled for video class) card isn't fast enough for something over a
Mini 1.
A V30/U3 card is, 30MB/s = 30*80 = 240Mbps
There are plenty of very inexpensive V30 cards (Even a Sandisk Extreme V30 isn't that expensive now) if that's the case. A V60 (480Mbps) card would be overkill as I am not aware of any DJI drones needing beyond 240Mbps let alone 480Mbps.
If it's a V30, just ignore as even if it was going slower than anticipated, there's still a lot of headroom between its 15MB/s maximum writing and the card's 30MB/s maximum rated capability.
