When reaching the prototype stage for the system development, it is important to verify that the TBW target can be achieved. This validation should include the full system stack, including the end application, operating system, and actual storage drivers. The goal is to apply an accelerated workload that reflects what the eMMC storage device will be subjected to daily. This will age the device accordingly. A common mistake is to use storage bench marking software, stress applications or low-level script commands, such as Linux dd, to provide a stress load to the storage device. This will not yield a Write Amplification Factor value that represents the end application. As a result, the product may age differently than when in the field while subjected to normal application workloads. Validation with expected end-application workloads is critical for verifying device life targets.
