Multi-non-volatile memory solid state drive block-level failure prediction with unified device log

A storage device is disclosed. A first storage media may store data. The first storage media may be of a first storage type, and may be organized into at least two blocks. A second storage media may also store data. The second storage media may be of a second storage type different from the first type, and may also be organized into at least two blocks. A controller may manage reading data from and writing data to the first storage media and the second storage media. Metadata storage may store device-based log data for errors in the storage device. The drive-based log data for errors may include a unified log data for the first storage media and the second storage media. An identification circuit may identify a suspect block in the at least two blocks in the first storage media and the second storage media, responsive to the unified log data. Parameters for the first storage media and the second storage media may be derived from a unified parameter in the unified log data in proportion to the number of write operations and the number of read operations to each storage media, relative to the number of write operations and the number of read operations of the storage device.
