Abstract: The present disclosure illustrates a method of extending a lifetime of a solid state disk (SSD). The SSD includes a flash memory which is a multi-level cell (MLC) flash memory. The method includes steps of: setting a number of logic blocks of the SSD to be one-half of a number of physical blocks of the flash memory; reading, by a control unit of the SSD, a write/erase times of each of the physical blocks of the flash memory; and converting the physical block, of which a number of the write/erase times exceeds an upper limit of the write/erase times, from a multi-level storage format to a single-level storage format. A number of the logic blocks is a constant value.

Abstract: A data storage device includes a physical storage unit, an authentication unit and a control unit. The authentication unit has a unique identification code. The control unit is electrically connected with the physical storage unit and configured to receive an identification command corresponding to the unique identification code. When the control unit receives the identification command, the control unit generates a logical block starting address and an available space according to the identification command, and determines a specified physical accessing block of plural physical accessing blocks of the physical storage unit according to the logical block starting address and the available space. The logical block starting address is a positive integer. In addition, a size of the physical accessing block is smaller than or equal to a size of the physical storage unit.

Abstract: A solid state drive (SSD) with a hybrid storage mode includes a flash memory, and a data processing module in information communication with the flash memory. The flash memory includes a first storage sector that stores data by a first potential storage mode, and a second storage sector that stores data by a second potential storage mode. The first storage sector corresponds to physical block addresses P0 to PM?1 and logical block addresses L0 to LM?1. The second storage sector corresponds to physical block addresses PM to PM+N?1 and logical block addresses LM to LM+1?1. The data processing module has a data processing mode. In the data processing mode, the data processing module identifies the logical block address included in a command, and executes the command at the corresponding physical block address. Accordingly, an SSD having a high stability and a high data storage capacity is provided.

Abstract: A loading method includes steps of providing a storage device and a system, among which the storage device having at least one physical storage partition is installed in the system, booting the system, loading an identifying program, inputting an identifying information corresponding to an user, and loading the physical storage partition of the storage device corresponding to the user according to the identifying information. As a result, accesses of unauthorized users are avoided, and external accesses and software cracking are also avoided. Meanwhile, the management of the system is simplified, and a real multiboot function is achieved.
