Peak performance is defined as the typical best case performance that the product will be able to achieve when the product is preconditioned as mentioned and host commands are aligned on 4KB boundaries. Sustained performance is defined as the worst case performance that the product will be able to achieve when the product is preconditioned as mentioned and host commands are aligned on 4KB boundaries. For models that support Lifetime Endurance Management, write values also take into account the worst case performance throttling that may occur to ensure the product meets specified reliability specifications.
