Title (EN) OVERPROVISION CAPACITY IN A DATA STORAGE DEVICE
(FR) SURPROVISIONNEMENT DE CAPACITÉ DANS UN DISPOSITIF DE STOCKAGE DE DONNÉES
Abstract:
(EN) A data storage module includes a non-volatile memory and a controller. A method performed in the data storage module includes receiving an overprovision capacity instruction from a host device. The method further includes updating a file system table of the non-volatile memory to indicate, by designating logical addresses in the file system table as being in use, that the logical addresses are used without reducing an amount of free physical space in the non-volatile memory.
(FR) L'invention concerne un module de stockage de données qui comprend une mémoire non volatile et un contrôleur. Un procédé effectué dans le module de stockage de données consiste à recevoir une instruction de surprovisionnement de capacité en provenance d'un dispositif hôte. Le procédé consiste en outre à mettre à jour une table de système de fichiers de la mémoire non volatile afin d'indiquer, par désignation d'adresses logiques dans la table de système de fichiers comme étant en utilisation, que les adresses logiques sont utilisées sans réduire une quantité d'espace physique libre dans la mémoire non volatile.
