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 typical 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 boundar-

ies. Write values also take into account the worst case performance throttling that may occur to ensure the

product meets specified reliability specifications.

Due to the nature of Flash memory technologies there are many factors that can result in values different than

those stated in this specification. Some discrepancies can be caused by bandwidth limitations in the host

adapter, operating system, or driver limitations. It is not the intent of this manual to cover all possible causes of

performance discrepancies.

When evaluating performance of SSD devices, it is recommended to measure performance of the device in a

method that resembles the targeted application using real world data and workloads. Test time should also be

adequately large to ensure that sustainable metrics and measures are obtained.
