Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A storage device comprising: a host device interface through which the storage device can communicate with a host device; and a controller in communication with host device interface, wherein the controller is configured to: obtain a trace of trim and write commands sent to the storage device; and for each trim command in the trace: identify a subsequent write command to a same logical block address (LBA) as the trim command; and calculate an elapsed…
