Abstract: A computing system includes a storage device and a processor. The storage device includes a plurality of nonvolatile memory devices, and stores user data and latency information in the plurality of nonvolatile memory devices. The processor receives the latency information from the storage device, determines a polling delay time based on the latency information, transmits a storage device command to the storage device, and initiates polling that checks a state of the storage device, after expiration of the polling delay time, as determined from a time when the storage device command was transmitted.
