For all Blu-Ray media burning tests, we used either Nero Burning ROM or ImgBurn. We created 25GB, 50GB, 100GB and 128GB ISO files from our HDD and we burned them at 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 Pioneer drive doesn't support Blu-Ray measurements so we used only the HLDS BH51N Blu-Ray drive to "measure/scan" the burned discs for burn quality.

According to the official specifications, the Pioneer BDR-X13J/S can write BD-R 6x, BD-R DL 6x, BD-R TL 4x, BD-R QL 4x, BD-R (LTH) 6x, BD-RE 2x, BD-RE DL 2x, BD-RE TL 2x, M-DISC(BD) SL 4x, M-DISC(BD) DL 6x, M-DISC(BD) TL 4x
