The storage configured to store data. The controller configured to perform a normal read operation based on a default read voltage in accordance with a read request of a host device and to perform a read retry operation using at least one retry read voltage when the normal read operation fails. The controller may comprises a hit ratio table configured to store read success records as hit ratios of retry read voltages in association with workloads, each workload being associated with a set of retry read voltages, and a read voltage determiner configured to determine the workload when the normal read operation fails and to select the set of retry read voltages associated with the determined workload, the retry read voltages in the selected set being ordered from a highest hit ratio to a lowest hit ratio."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Data storage device and method of operating the same","description":"A data storage device may include a storage and a controller.
