Abstract

A storage device includes at least one computer readable medium and an interface for use in coupling the storage device to a host. The interface is further for routing information to and from the at least one computer readable medium. At least one buffer is located in a reserved area of the at least one computer readable medium. Lastly, a controller is provided for logging characteristic operational information of the storage device in the at least one buffer upon an occurrence of an event initiated by the host. The characteristic operational information includes at least a power on hours (POHs) and a corresponding time stamp benchmark information.
