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.
