Abstract
A mechanism is provided for a flash array test engine. The flash array test engine includes a circuit. The circuit is configured to generate test workloads in a test mode for testing a flash device array, where each of the test workloads includes specific addresses, data, and command patterns to be sent to the flash device array. The circuit is configured to accelerate wear in the flash device array, via the test workloads, at an accelerated rate relative to general system workloads that are not part of the test mode. The circuit is configured to vary a range of conditions for the flash device array to determine whether each of the conditions passes or fails and to store failure data and corresponding failure data address information for the flash device array.
