1. A method of managing storage devices, the method comprising:
generating a wear imbalance level indicating a variance between a first wear level of a first set of storage devices and a second wear level of a second set of storage devices, the first set of storage devices being different from the second set of storage devices;
after generating the wear imbalance level, performing a comparison operation that compares the wear imbalance level to a predefined imbalance threshold, a result of the comparison operation indicating that the wear imbalance level is above the predefined imbalance threshold; and
in response to the result of the comparison operation indicating that the wear imbalance level is above the predefined imbalance threshold, providing the first set of storage devices as a first storage tier and the second set of storage devices as a second storage tier.
