Abstract
A Solid-State Disk (SSD) Manufacturing Self Test (MST) capability enables an SSD manufacturer to generate and load tests onto SSDs, run the tests, and gather results. The SSDs self execute the loaded tests when powered up. The self executing is while coupled to a host that loaded the tests or while coupled to a rack unable to load the tests but enabled to provide power to the SSDs. The rack is optionally cost-reduced to enable cost-efficient parallel testing of relatively larger numbers of SSDs for production. The host writes the tests to an 'input' SMART log of each SSD, and each SSD writes results to a respective included 'output' SMART log. The commands include write drive, erase drive, SATA PHY burn-in, delay, and stress mode. The SSD MST capability is optionally used in conjunction with an SSD virtual manufacturing model.
