For all Blu-Ray media burning tests, we used ImgBurn. We created 25GB, 50GB, 100GB, and 128GB ISO files from our HDD and we burned them on the disc. Max writing speed was set to the burning software. Reading speeds were performed with OptiDriveControl (for 25GB/50GB discs) and with QPxTool (for 100GB/128GB discs). Note that the Verbatim External Blu-Ray Recorder doesn't support Blu-Ray Quality measurements with OptiDriveControl or other optical storage software.
