Abstract
A storage device capable of meeting the reliability has a storage capacity and the reliability of the storage device is defined. The storage device includes at least one first storage unit, at least one second storage unit, and a control unit. The first storage unit forms the storage capacity of the storage device. The second storage unit is allocated to form a spare capacity according to the storage capacity and the reliability. The second storage unit replaces the bad blocks in the first storage unit. The control unit controls the first storage unit and the second storage unit to transmit and convert the data with an application system. Thereby, by allocating the spare capacity of the second storage unit, the different reliability requirement is met, and the storage capacity of the first storage unit is unaffected.
