Which flash drive is most used for temporary ASIair file storage?

I am using micro sd cards. I have a bunch of Sandisk Extreme 64GB cards sitting around from other photo / video stuff and just use those. I try to not leave a lot of data on the card before offloading, but that is just paranoia that I will lose data. I also use the 533MC Pro so my files are small and it would take quite a few subs to fill the cards I use.

I use a SanDisk 512GB Ultra Fit USB 3.2 Gen 1 Flash Drive.

Are there any particular reasons why you chose so much memory?

I'm guessing you are using it also as a permanent file storage?

I normally image with a dual/triple scope setup and the space is needed. I plan on using it as permanent storage, it has fairly fast read/write speed. Also with I get home, I can pop it off the scope and offload images on my PC

I use a 64GB Sandisk, but never use more than 10 to 15 GB in a session. I transfer the contents of the drive to my working computer after every session. If you follow the same process, 32GB should be plenty...

Yeah, I think offloading it every time is the best way to do it for me. So I'm going for 32GB. Or maybe 64GB if I'm gonna take 3200 frames of the moon in one session.
