Différences entre SD, SDHX et SDHC

Avant d'acheter une carte mémoire SD, il faut comprendre ce que signifient toutes ces sigles qui peuvent sembler confus. Pas d'inquiétude, chez PcComponentes nous sommes ravis de vous aider et allons passer en revue ce qui se cache derrière chacun de ces acronymes. SD signifie Secure Digital, Secure Digital High Capacity et Secure Digital eXtended Capacity correspondent à SCHC et SDXC respectivement. Les différences de sécurité entre ces différents modèles sont négligeables ; c'est plutôt la vitesse de la mémoire et la capacité maximale qui déterminent l'usage de telle ou telle nomenclature. Les cartes SD incluent toutes celles qui dépassent les 2 Go, tandis que pour les cartes SDHC, la capacité commence à 4 Go et les SDXC se caractérisent par une très grande capacité de stockage.

Qu'est-ce que la classe d'une carte mémoire ?

La classe d'une carte détermine sa vitesse de transmission de données (lecture et écriture) et s'exprime généralement par un chiffre. Nous retrouvons ce système sur les cartes SD. Le chiffre indiqué correspond à la vitesse de lecture et d'écriture en Mo/s, si bien qu'une SD de classe 2 offre une vitesse de 2 Mo/s alors qu'une classe 10 sera 5 fois plus rapide. En ce qui concerne les SDHC et SDXC, on peut lire la mention UHS : il s'agit de l'acronyme de la norme adoptée par ces cartes et qui permet d'atteindre des vitesses supérieures à 100 Mo/s. La classe la plus basse est UHS-I, dont la vitesse minimale de lecture et d'écriture débute à 10 Mo/s, tandis qu'une UHS-3 peut grimper à 30 Mo/s.
