Merci pour ces retours précis 🙂

Je vais donc un peu patienter pour la Pine64 et passer à la 3B+.

@km782 I have used 64 Gb SD Cards with the Rock64 and Rockpro64 without any issues in the past. Sure you bought yours from a reliable store?
Anyway, I’d rather recommend yo use an USB Stick to store your roms instead of using a high capacity SD Card.
