Storage device with a display device for indicating a state

A storage device comprising:

• nonvolatile memory devices;
• a controller configured to control the nonvolatile memory devices;
• a display device;
• a detection circuit;
• and
• a display controller configured to control the display device,
• wherein the display controller is further configured to control the display device to display different colors respectively corresponding to states of the storage device, the states comprising an access state in which the controller accesses the nonvolatile memory devices according to a request from an external host device, a standby state in which the controller is ready to perform the request from the external host device, a device fail state in which the controller and the nonvolatile memory devices cannot operate, and a replacement state in which the controller and the nonvolatile memory devices are selected for replacement,
• wherein the display controller is further configured to determine that the storage device is in the replacement state in response to a signal from the detection circuit being activated while the storage device is in the device fail state, and
• wherein the display controller is further configured to maintain a previous state in response to the display controller being not in the device fail state and the signal being activated.

A storage device comprising:

• nonvolatile memory devices;
• a controller configured to control the nonvolatile memory devices;
• a detection circuit configured to activate a signal in response to an external adjustment on the storage device;
• a display device;
• and
• a display controller configured to control the display device,
• wherein the display controller is further configured to change a color of the display device in response to the nonvolatile memory devices and the controller being in a device fail state and the signal being activated, and
• wherein the display controller is further configured not to change the color of the display device in response to nonvolatile memory devices and the controller not being in a device fail state and the signal being activated.
