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:
Brand/Model | Experience | User |
|---|---|---|
Onn 128GB | Not working - Gets stuck in mega65-fdisk somewhere within  | traymond |
