Folks have reported reasonably good success with most SDHC (and SDXC?) cards, though I believe there are a few brands/models out there that have been problematic. Will try keep a list here of brands/models that users have had success/difficulties with:
General Advice:
Stick to big-brands (SanDisk / Kingston)
SDHC is recommended
WARNING: some SDXC cards work, others don’t
Aim for 32GB or less

Kingston 32GB (SDHC?) | Ok - Yaru mentioned that his SD-card would sometimes fail to be detected as SDHC, but he found the problem went away after using a HDMI splitter (discord) | Yaru |
