    摘要: Hybrid storage apparatus and logical block address assigning methods for the hybrid storage apparatus are provided. A hybrid storage apparatus includes a plurality of storage apparatuses having different writing methods, and a controller to combine the storage apparatuses as a single storage apparatus, to assign one or more logic block addresses to the single storage apparatus, and to access the storage apparatuses using the logic block addresses. The address assigning method of a hybrid storage apparatus includes searching and detecting one or more storage apparatuses included in a hybrid storage apparatus when an initially set condition is generated, combining the storage apparatuses as a single storage apparatus, assigning one or more logic block addresses to the single storage apparatus, and accessing the storage apparatuses using the logic block addresses.

    摘要: A data storage system includes data storage including at least one data storage disk driven by a spindle motor and a control circuit coupled to the data storage and configured to be coupled to a main power source and a backup power source. The control circuit is configured to detect failure of the main power source, to responsively write data to the data storage while powered by the backup power source, and to subsequently recharge the backup power source using the spindle motor. The control circuit may be configured to further write data to the data storage using the recharged backup power source. The data storage system may further include a head configured to read and/or write data to or from the at least one data storage disk, and the control circuit may be configured to park the head using the recharged backup power source.
