In one embodiment, the SMR drive may include a main store to store user-accessible data, a media cache and media scratchpad to store internal data temporarily for internal operations, and a storage controller to process read and write requests. In some cases, the main store comprises a shingled media partition and an unshingled media partition. The storage controller may designate one or more data tracks from the shingled media partition as temporary data track guard bands. In some embodiments, a track range is selected based at least in part on at least one of an amount of data in the media cache, a size of the new data in the media cache, and an association between the new data in the media cache and data currently stored within the selected track range."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Maximize SMR drive capacity","description":"Systems and methods for maximizing shingled magnetic recording (SMR) drive capacity are described.
