1. A storage device comprising:
- a nonvolatile memory device; and
a controller configured to,communicate with a host through a first port,communicate with an external storage device through a second port,control the nonvolatile memory device based on first mapping information,receive second mapping information from the external storage device,receive first write data from the host, andselectively transmit the first write data to the external storage device based on the second mapping information.

Abstract
Disclosed is a storage device which includes a nonvolatile memory device and a controller. The controller communicates with a host through a first port, communicates with an external storage device through a second port, and controls the nonvolatile memory device based on first mapping information. The controller is configured to receive second mapping information from the external storage device, receive first write data from the host and to selectively transmit first write data to the external storage device based on the second mapping information.

12. A storage system comprising:
-
a host; a first storage device including a first nonvolatile memory device, the first storage device configured to communicate with the host through first ports; and a second storage device including a second nonvolatile memory device, the second storage device configured to communicate with the first storage device through second ports, wherein, the first storage device is configured to receive first write data from the host and to transmit the received first write data to the second storage device, the second storage device is configured to store the received first write data, and a first logical address of the first write data is allocated, by the host, such that the first logical address corresponds to a first storage area of the first storage device. - View Dependent Claims (13, 14, 15)
