Disclosed is a computing system which includes a storage device and a host. The storage device may include a nonvolatile memory, and the host may control the storage device based on a physical address of the nonvolatile memory and may send an asynchronous event request command to the storage device. The storage device may monitor the nonvolatile memory and may send an asynchronous event request corresponding to the asynchronous event request command to the host based on the monitoring result. The asynchronous event request may include requesting another command from the host based on the monitoring result. In some aspects, the host may send an erase command for erasing to erase a selected memory block of the nonvolatile memory to the storage device. In response, the storage device may send an erase pass response or an erase delay violation response to the host in response to the erase command.
