Storage system

A storage system comprising:

• a package stocker configured to store a plurality of semiconductor packages, each of the plurality of semiconductor packages including one or more nonvolatile memory dies;
• a drive including at least one socket on which a semiconductor package among the plurality of semiconductor packages is able to be detachably mounted;
• a host apparatus communicatively connected to the drive and configured to execute reading or writing data from or to the one or more nonvolatile memory dies of the semiconductor package mounted on the socket;
• and
• a package transport device configured to transport each of the plurality of semiconductor packages between the package stocker and the drive,
• wherein the host apparatus is further configured to:
• determine a first semiconductor package that includes a first nonvolatile memory die to be accessed, among the plurality of semiconductor packages;
• when the first semiconductor package is mounted on the socket of the drive, execute reading or writing data from or to the first nonvolatile memory die;
• and
• when the first semiconductor package is not mounted on the socket of the drive, cause the package transport device to transport the first semiconductor package to the drive, and to mount the first semiconductor package on the socket of the drive.
