Abstract

La présente invention concerne un module disque qui peut être transformé et utilisé en tant que dispositif de mémoire pour un hôte au moyen d'une multiplicité de mémoires non volatiles portatives. Un module disque comprenant plusieurs micro-mémoires flash, plusieurs micro-cartes SD, installées sur ce dernier est conçu sous forme d'un disque unique. Par conséquent, le module disque est non seulement plus intéressant que d'autres disques durs classiques en termes de poids, de facilité de transport, de vibration et de consommation électrique, mais présente également une excellente capacité d'extension comparativement à une capacité de stockage déterminée d'un SSD classique, ce qui permet ainsi d'obtenir une configuration de disque désirée produite en fonction des besoins du fabriquant et de l'utilisateur. De plus, un stockage RAID peut être configuré sur un disque physique au moyen de fonctions RAID, ceci assurant plus de praticité que n'importe lequel des autres disques existants.
