Abstract
A device for detecting zone parallelity includes a detection control circuit configured to generate respective first and second requests for first and second zones among a plurality of zones included in a solid state drive (SSD). An SSD controller is configured to control the SSD by generating a first command and a second command corresponding to the first request and the second request, respectively, and to schedule the first command and the second command. The detection control circuit determines zone parallelity of the first and second zones using response characteristics of the responses of the SSD to the first request and the second request. The response characteristics may include a latency of a response.
