Abstract
A data storage device includes a relocation management system that determines whether to perform a relocation operation based on an operating temperature, performance metrics and/or energy metrics associated with the data storage device. The relocation management system uses the operating temperature to identify a performance threshold and an energy threshold. Each threshold indicates whether the relocation operation is a first relocation method or a second relocation method. If the validity count of a memory block included in the relocation operation is below each threshold, the first relocation method is selected. If the validity count of the memory block is above both thresholds, the second relocation method is selected. However, if the validity count of the memory block is in a tradeoff range, the relocation management system selects a relocation method based on a tradeoff between performance metrics and energy consumption metrics.
