In my opinion, for clarity and transparency before purchasing a device, it would be necessary that manufacturers clearly indicate on the data sheets of their devices more information about the device specifications:
- The type of compatible microSD cards (Ex: SDHC / SDXC / ...)
- The type of supported file systems. (FAT32 / exFAT / ...)
- The maximum theoretical capacity of supported microSD card (Up to 32GB/ UP to 2TB /...)
- The class of the card reader, to know the maximum speed of compatible cards (Classe 10: Min Write Speed: 10 MB/s 25 MB/s....)
How to get this information without relying on manufacturer declarations?
