Abstract
According to one embodiment, a storage device includes a first storage region assigned to a first user and a second storage region assigned to a second user. A first controller is capable of providing a data protection function to the first and second storage regions, and a second controller is capable of providing the data protection function to the second storage region. The first controller stores a table with information about the data protection function. The second controller can refer to the table. The first controller has a authority to execute a user authentication for the first storage region and the second storage region to determine whether the data protection function can be provided for the first or second storage regions.
