Abstract
The present invention extends to methods, systems, and computer program products for testing storage device power circuitry. A storage device controller includes an embedded test program. The storage device controller executes the test program in response to receiving a test command. In one aspect, the test program issues a plurality of different command patterns to test shared power circuitry of storage device components (e.g., shared by an array of NAND flash memory devices). The test program identifies a command pattern that causes a greatest total current draw. In another aspect, the test program issues a specified command pattern (possibly repeatedly) to shared power circuitry to determine if the shared power circuitry fails.
