Abstract: A data storage device and method for lane detection and configuration are provided. In one embodiment, a data storage device is provided comprising a memory, an interface, and a controller. The controller is configured to detect whether a cable coupled with the interface is providing a first channel configuration signal that indicates that the cable is in a first cable orientation or a second channel configuration signal that indicates that the cable is in a second cable orientation. In response to detecting that the cable is not providing either the first or the second channel configuration signal, the controller uses a default lane configuration to communicate with the host via the cable. Other embodiments are possible, and each of the embodiments can be used alone or together in combination.

Abstract: A data storage device and method for lane selection based on thermal conditions are provided. In one embodiment, a data storage device is provided comprising a memory and a controller. The controller is configured to determine that action is needed to control a thermal state of the data storage device; and in response to determining that action is needed to control the thermal state of the data storage device, send a request to a host to reduce a number of lanes the host uses to communicate with the data storage device, wherein reducing the number of lanes reduces an amount of heat generated by the data storage device. Other embodiments are possible, and each of the embodiments can be used alone or together in combination.
