Advantageously, the most recent version of data associated with the overlapped logical block address is stored in cache in the non-volatile solid-state device, even when the subsequent disk write operation results in the overlapped logical block address being trimmed from cache or otherwise invalidated. Consequently, data associated with the overlapped logical block address can be accessed more quickly than data written to the magnetic storage device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Hybrid-HDD policy for what host-R/W data goes into NAND","description":"In a cache policy for a hybrid drive having a magnetic storage device and a non-volatile solid-state device, the hybrid drive is configured to write the most recent version of data associated with a l","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9703699","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
