1. A system for controlling background wear leveling, comprising:
memory; and
at least one processor coupled to the memory and collectively configured to at least:
increment a first counter in response to receiving a host write trigger;
compare the first counter to a first threshold;
in response to the first counter meeting the first threshold, decrease the first counter by the first threshold,
increase a second counter in response to the first counter meeting the first threshold;
compare the second counter to a second threshold; and
in response to the second counter meeting the second threshold:
decrease the second counter by a value of the second threshold; and
trigger background wear leveling.
