Slightly off topic, but why is there anything significant about the 400gb increment/size? It's not the standard 8/16/32/.../256/512gb etc size increments that I'm used to.

Maybe a lower quality chip than a 512GB and they can just fuse off a portion? 200GB microsd cards are a thing too.

Usually stuff like this is because of product binning: https://en.wikipedia.org/wiki/Product_binning

Basically, chips which don't work completely still have their partial capacity used. This is also why, eg, some Apple products had 7 cores. https://9to5mac.com/2020/11/11/wh...air-specs/

Yea 4K on GoPro is sensitive about the memory card and battery. 1080 it doesn't really care….

400GB is an odd size. This is an older card with a lower speed rating

It's possibly a 512GB card with a bad section during test so they lock that sector and sell it as 400G
