The primary storage disks have higher performance than the secondary storage disks. The storage device detects an access frequency of a data block stored in the secondary storage disks. Based on the access frequency of a data block, the storage device determines that the access frequency of the data block reaches an access threshold value. And then, based upon the determination, the storage device moves the data block to the primary storage disks. After that, the storage device divides the data block into a plurality of sub-blocks and detects an access frequency of each of the sub-blocks. Finally, the storage device moves one or more of the sub-blocks of which access frequencies are less than the access threshold value back to the secondary storage disks."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for a storage device processing data and storage device","description":"A method for managing data in a hierarchical storage device which includes primary storage disks and secondary storage disks.
