Abstract

A method and system for reading data from a non-volatile mass storage device is provided. The method includes, performing logical configuration for the non-volatile mass storage device, wherein file data is allocated addresses in a virtual logical address space; and data identified by virtual logical addresses is read by a host system. The system includes a file storage segment that reads and writes data on a file-by-file basis, allowing a host system to access data from the non-volatile mass storage device using a file interface format; and a logical interface segment that allows the host system to access data using logical addressing, wherein the host system is unaware of a storage format under which data is stored on a file-by-file basis.
