Memory card speeds for Mini 4K

[BenThe]

Hello everyone,

I flew the Mini 4K for the first time recently, and I saw a popup message warning me of a slow SD card. I put a 256GB UHS-I U3 A2 V30 Class 10 microSD card in it, which is advertised of being capable of 150MB/s read 100MB write with a reader, and at least 100MB/s read and 90MB/s write in other conditions. I am assuming the Mini 4K falls in the latter, but it should still be able to handle the 4K 30fps video I was taking. The footage off the card looked okay with no stuttering to my untrained eyes.

Any thoughts on this is much appreciated!

You didn't say which brand and model for the microSD card. Much of the advertised specs are fake.

It is a Team Group Pro + 256GB, technically not on DJI's list of approved cards, but not a bad card supposedly.

I would recommend sticking to the well known brands such as SanDisk. As @mavic3usa mentions there are a lot of fakes around that not only fail to meet the SD Card standards set by the SD Association but also falsely report their speed and capacity.

Video needs a sequential write to storage and V30 is only guaranteed to 30 Mega Bytes/Sec. V60 is the SD association’s recommendation for 4K.

The data written to storage is also highly influenced by the video format and codec used.

I occasionally get that message with the card I always use in my Air 2S but the videos always come out fine. I'm not sure if it's a momentary hiccup or what but it doesn't affect what I'm shooting. It only happens once in a while.
