Hybrid storage apparatus and logical block address assigning method

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.

主权项

1. A memory device storing instructions that, when executed by a computer, performs a method comprising:
searching and detecting at least one of a first data storage apparatus and one or more second data storage apparatuses included in a data storage device when a set condition occurs; assigning a first set of logic block addresses to the first data storage apparatus; assigning a second set of logic block addresses to the one or more second data storage apparatuses, wherein the first data storage apparatus and the one or more second data storage apparatuses are accessed as a sequentially-addressed single storage apparatus; copying a system file stored in a first system file area of the first data storage apparatus into a specific area of the one or more second data storage apparatuses as back-up data; and copying the system file from the specific area to a second system file area of the one or more second data storage apparatuses when the system file is not detected in the first data storage apparatus.
