S’y retrouver dans les diff\u00e9rents types de cartes SD, est devenu le parcours du combatant. Capacit\u00e9, format de fichiers, classe de vitesses et bande passante du bus, on n’y comprend rien ! Cet article va nous aider \u00e0 y voir clair.<\/p>\n

Peu \u00e0 peu, la face avant des cartes SD est devenue plus compliqu\u00e9e \u00e0 lire qu’une ordonnance du m\u00e9decin. Voici comment lire les logos.<\/p>\n

La capacit\u00e9<\/h2>\n

La capacit\u00e9 est bien entendu indiqu\u00e9e sur la carte, mais elle est accompagn\u00e9e d’un logo indiquant le format de fichiers. Il y en a 3 :<\/p>\n

La vitesse du bus<\/h2>\n

Cela repr\u00e9sente la vitesse maximum atteignable par l’interface de la carte. (\u00c0 lire\u00a0\u00e9galement l’article sur la vitesse des carte UHS-II<\/a>)<\/p>\n

La classe<\/h2>\n

Comme les 2 valeurs pr\u00e9c\u00e9dentes ne permettent pas avec certitude de savoir quelle vitesse r\u00e9sultante sera disponible, un nouveau logo a \u00e9t\u00e9 cr\u00e9\u00e9 : la classe. C’est la vitesse minimum garantie.<\/p>\n

Et enfin…<\/h2>\n

Enfin, il reste une indication qui est tr\u00e8s fr\u00e9quente mais n’est pas d\u00e9finie par la SD Card Association. Cette valeur est indiqu\u00e9e \u00e0 l’aide d’un nombre\u00a0suivi du signe \u00ab\u00a0multipli\u00e9\u00a0\u00bb. C’est la vitesse th\u00e9orique maximale. En gros la vitesse que vous \u00eates s\u00fbr de ne jamais atteindre…<\/p>\n

Elle est indiqu\u00e9e en multiple de 150 KB\/s (vitesse de lecture d’un CD il y a longtemps…). Par exemple 400 x signifie 400 x 150 KB\/s = 60 MB\/s.<\/p>\n
