    摘要: A method and storage device for assessing execution of trim commands are provided. In one embodiment, a trace of trim and write commands sent to a storage device are obtained. For each trim command in the trace, a subsequent write command to a same logical block address (LBA) as the trim command is identified, and an elapsed time between the trim and write commands is calculated. This information can be used to display a histogram and/or to optimize when the storage device executes trim commands and/or when the host device issues trim commands.
