The read/write cache device includes a meta-information part, a recency/frequency (RF) table part, a mapping table part, and a log area. The meta-information part provides information about whether metadata has integrity and information about the version of metadata stored in two metadata regions. The RF table part provides information about the recency and frequency of each of low-speed segments of a plurality of high-speed and low-speed segments and information about whether each of the low-speed segments is cached, in order to maintain the consistency of the metadata. The mapping table part provides information about a low-speed segment that is cached to each of the high-speed segments. The log area provides changed caching information that is not applied into the mapping table part."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Read/write cache device and method persistent in the event of a power failure","description":"A read/write cache device and method persistent in the event of a power failure are disclosed herein.
