Being myself in the situation that I'd need a new microSD card for my Xperia X, I tried to figure out what cards would actually work (after formatting using a compatible filesystem) and which would not.

Based on https://together.jolla.com/question/169040/sailfishx-microsd-card-not-detected/ and my own experience I gathered that some Kingston 16GB and 32GB cards don't work, just like some SanDisk 32GB cards, and the Transcend 16GB (UHS-1) I tried, while at least some SanDisk 32GB cards do work (as well as the Kingston 4GB card I had, but that's not very usable anymore). Clearly, brand names and capacities just isn't enough to be able to know if a card should work or not.

I thought it might be possible to have something useful by collecting model numbers (since cards with pretty much identical cover might have different internals). Knowing the oemid of the card might also tell something but that's something you can't check before buying a card.

Please help fellow sailors by adding your experience. I made this a community wiki so you may add directly edit it.

Before reporting a card as failing, please make sure you've made sure that the card has been formatted with a filesystem SFOS X is compatible with, like FAT32, VFAT, ext4, UDF or BTRFS(https://jolla.zendesk.com/hc/en-us/articles/201997993)

Please include also the model number so that others can be sure that they know they are looking at the same card as the internals can change without the model name or branding changing. Model number can usually be found in the packaging and/or the shop catalog. Some manufacturers also have some other codes/numbers, but usually with memory devices the model number includes the capacity of the device in a clearly readable form, and when doing a web search with the model number, one should be able to get hits on manufacturer/reseller product pages.

Fails:

Brand     Capacity  Model no
