A data relocation system includes a storage controller device coupled to first storage device(s) that operate at first data access speeds, and second storage device(s) that operate at second data access speeds that are higher than the first data access speeds. During a first time period, the storage controller device monitors first data that is stored in the first storage device(s) to identify a first data access frequency for the first data, and determines that the first data access frequency for the first data during the first time period indicates that a second data access frequency for the first data will exceed a data access frequency threshold during a second time period that occurs immediately following the first time period. In response and during the second time period, the storage controller device relocates the first data from the first storage device(s) to the second storage device(s).
