Abstract: A storage device includes a storage controller and a host interface which sends an address translation service request to a host. The host interface includes an address translation cache which stores first address information included in the address translation service request, and an address translation service latency storage which stores latency-related information including a first time until the address translation cache receives an address translation service response corresponding to the address translation service request from the host. After the host interface sends the address translation service request to the host based on the latency-related information including the first time, and after the first time elapses, the storage controller polls the host interface.
