The disclosure is related to systems and methods of concurrent actions for data storage. A controller may be configured to initialize a first data storage medium and a second data storage medium. The controller may receive a command when the first data storage medium is initialized but before the second data storage medium is initialized. The controller may service the command when the command utilizes the first data storage medium and the initialization for the second data storage medium is not complete. A controller may also be configured to send an indicator to a host that the system is ready to receive commands when a first data storage device is initialized, but a second data storage device is still in an initialization process.
