I currently have a 128 GB microSD in my Switch. I bought a 512 GB to upgrade it, I've just never gotten around to actually transferring it. I need to now though as I'm quite low on memory on the 128 GB.
That's why I went to 512GB! 256 was cheaper, but I didn't want to come into the problem of not being able to download all the games I've ever purchased.
Future-proofing for when the eShop closes (years and years from now).
I had a 200GB but noticed a couple months ago it was starting to get full so now I have a 400GB card. (I do take a ton of screen shots and video clips and I have not deleted any since I got a switch in 2017)
Neither was in the poll but I voted 512 as that’s the closest one.
I took a 128 gb SD card, the official Nintendo one, to be sure it was of good quality and didn't get corrupted over time, I thought it would be enough but if I went back I'd get 256 gb. The Eshop summer sales are very convenient and filled a lot of memory
I have an 8GB and a 16GB. Thus far I've only ever used them for screenshots, because whenever I try to download a game update to either of them I get an error saying I can't.
....Oh. Wait. As I type this, I just remembered how small these ones are. They probably can't fit any significant update batch on them, since everything has a massive day one patch these days. I always thought I had a 128GB one for some reason.
