1. A method of reducing the impact of drive parameter writes on solid state drive (SSD) performance, comprising:
saving one or more SSD drive parameters of an SSD to volatile memory of the SSD using an SSD controller;
detecting a power-loss condition in the SSD; and
in response to detecting the power-loss condition, copying the one or more SSD drive parameters from the volatile memory of the SSD to non-volatile memory of the SSD,
wherein the SSD drive parameters include a drive health parameter.
