Abstract: An aluminum alloy material for a vehicular component is provided. The aluminum alloy material includes 0.1 wt % or less of Si, 0.1 wt % or less of Fe, 0.1 to 0.4 wt % of Cu, 1.0 to 1.5 wt % of Mg, 4.5 to 5.5 wt % of Zn, 0.04 wt % of Ti, 0.2 wt % of Zr, and the balance being Al on the wt % basis. This aluminum alloy material exhibits improved properties in terms of yield strength, tensile strength, and elongation ratio, all of which contribute to the lightweighting of a vehicle.

Abstract: A method of operating a storage system, comprising: issuing a first command to write a first data to a first nonvolatile storage device; writing the first data to a second nonvolatile storage device if write condition is unstable; retrieving the first data from the second nonvolatile storage device; and writing the first data to the first nonvolatile storage device during a stable write condition, wherein whether write condition is stable is determined based on one of a sensor output or a memory access status signal, and wherein the memory access status signal is one of a predetermined value of retries, idling, access commands, or any combination thereof.
