SD card speed

Hello all

assuming NOT to use Raspberry’s boot SD card for music storage but just for the system, is there a big advantage in using a Class 10 SD card, or an ordinary class 4 will do?

Also: how big should it be?
Or better asked: how small can it be? :slight_smile:

Thanks in advance for help


Hello Alberto,

Volumio runs from RAM so the speed of the SD card has no influence to the running system. A slower card just could extend the boot time a bit and will take more time to flash it.

According to the card size have a look here :


All clear! Thanks!
