I was looking for my extra 128GB microSD cards but I seem to have used it all up in my GoPro cameras. I was going to buy another for backup yet could not find any locally. Wonder if it's the pandemic supply issue... Anyways then I found that Costco has Sandisk Extreme 400GB microSD cards for $42.99. Curious for that price it was worth trying. While I do not need that much in space, it's good to rotate this between my 128GB if it works. I did read that the Mavic 3 specs support it but no clue if the A2S did in the Fly app since I recall the max was 256GB. Lo and behold, A2S sees it although not the true 400GB due to filesystem or so, but I'm more than happy to have a backup card again!



Anyways confirming 400GB Sandisk Extreme microSD card does work! Tried a few photos and videos and all recorded fine.

wait until you get into the 1TB card.  best price i've seen is $99.

Ha, don't tempt me please!    Does the 1TB card work?

Thats a lot of space for phots

And if you get lazy and do not back up the card and loose the drone and more than 128gGb of video and photos how are you going to feel?

why wouldn't it?  pardon me but im not super technical so perhaps i can learn something from you or others who might chime in.  if the card is microSDXC, why wouldn't it "work?"  does size have something to do with it?  if by work you mean is it acceptable, endoursed, recommended, or appear on some approved list....but i'm talking about reformat it, recognized by drone, write files to it, able to read files on a computer later = work.  the SDXC standard goes up to 2TB now and i understand there isn't a commercially available 2TB card on the market so no one is going to list a 2TB card as compatible.  at the same time, it doesn't have to be listed in order for me to use it.  dji performs a limited test and creates a recommended list but they can't test everything especially future cards....so why are you surprised to see a 400gb card working in your drone?  i get it there are some devices that do weird things and simply won't accept a card bigger than what the programmer codes in the software but this is a dji and we should expect more, right?

for me, a 1TB card will come in handy when on vacation.  you can backup the card twice a day but i don't feel good about reformatting a card while on vacation.  i'd rather have multiple cards that i switch out daily plus whatever i backup on a computer (if i have one) but a once in a lifetime trip should mean you try to avoid any reformatting....that's my opinion.  at home, i reformat after every backup and outing, it's part of the pre-flight.

Can someone PLEASE explain this fascination with reformatting memory cards? I have never done it as a rule and do not remember that having caused me any problems.

Sure, glad to help. Formatting is the best method to clear the contents of a memory card.

Cheers.

this might be an old article and no longer applicable, but im old school:  https://www.bwillcreative.com/when-to-format-an-sd-card/

I heard that size is not important but rather how you use the card. My ex G/F disagreed ;-)

Works perfectly with Mavic Air 2S
