A solid-state drive (SSD) for handling an Asynchronous Event Request (AER) command includes a command receiving circuit and a command management circuit. The command receiving circuit is configured to receive at least one command from at least one host. The command management circuit is configured to determine if the received at least one command from the at least one host is an AER command, store the AER command into an AER queue reserved for deferred AER command handling, if the received at least one command is the AER command, and generate a dummy response for the AER command and release resources occupied by the AER command.
