摘要：
A data storage method comprises storing first data in at least a first data chunk, wherein the first data chunk is a logical representation of one or more sectors on at least a first disk drive in a storage system; storing first metadata, associated with the first data, in at least a first appendix, wherein the first appendix is a logical representation of a sector region on at least the first disk drive in the storage system, and wherein the first metadata comprises first atomicity metadata (AMD) and first validity metadata (VMD) associated with the first data; and storing a copy of the first VMD for the first data in at least one low latency non-volatile storage (LLNVS) device.
