Abstract
Mechanisms for reducing the impact of drive parameter writes on solid state drive (SSD) performance are provided, the methods including: 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 copying the one or more SSD drive parameters from the volatile memory of the SSD to non-volatile memory of the SSD. In some embodiments, the SSD is a NAND SSD. In some embodiments, the one or more SSD drive parameters include one or more of: a drive health parameter, a drive internal statistic, drive thermal information, drive debug information, a number of host and non-volatile memory read and writes, media error handling data, temperature and throttle information, and firmware download information. In some embodiments, the volatile memory is one or more of: random-access memory and dynamic random-access memory.
