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 pe rformance that the product will  be able to achieve when the 

product is preconditioned as mentioned and host commands are aligned on 4KB boundaries. 

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.
