Is there a recommended microSD for use with SX OS?

[Mohawk]

I am buying an SD card for the sole purpose of using with SX OS.

Are there any recommendations for the specs and/or types of SD cards for the best compatibility?

I plan to format it as FAT32.

I read on an older thread that it should be rated A1, U3. Any truth to that?

I have been using Sandisk SD cards without issues. 64gb, 128gb, 256gb and I just purchased the 400gb since it's only around $60.

Thanks,

I read in a thread on gba forums that the recommended cluster size for the FAT32 SD card for SX OS is 32k. Is that correct?
