A data storage device includes a storage media storing data and a controller that receives a de-allocation command and performs the de-allocation command according to a size of a de-allocation region. When a size of the de-allocation region is larger than a minimum erase unit of the storage media, the controller performs a first de-allocation operation to erase a part of the de-allocation region, an operation to notify the host of a completion of the de-allocation command after the first de-allocation operation, and a second de-allocation operation to erase the rest of the de-allocation region.
