NOTE: Please only use SD cards from Loxone.

SD cards have their own CPU which manages the flash memory.
For maximum performance, Loxone OS accesses many low-level functions of the card, unlike e.g. a digital camera. SD cards undergo a multi-week quality testing at Loxone before they are released for use in Miniserver Compact and for sales. Please only use SD cards approved by Loxone.
There is no guarantee when using other SD cards, and the stability of the Miniserver Compact is also affected.
