Due to similarities with the PX-716A drive, the CD measurements have been omitted and we will be posting the DVD Format measurements only.
Using both Pressed Single and Dual layer DVD media, as well as DVD±R-RW media along with the Nero CD-DVD Speed utility we got the following readings regarding the PX-716AL and its transfer rate capabilities.
Using Single Layer media, the 716AL managed to achieve first place among the three drives as shown in the above graph, with an average speed of 12.07X and an end speed of 16.17X.
The two layers of a PTP DVD-ROM disc are read sequentially with the drive starting reading from the inner part of the disc, which is the beginning of each layer, progressing towards the outer range, for each layer. Max supported speed in this case with the 716AL is 12X.
The graph shown above indicates the reading performance of the drive with OTP dual layer media. The first layer of an OTP dual layer DVD-ROM is read exactly the same way as the first layer of the PTP disc we tested previously. The difference here is the reading strategy of the second layer of the disc. The beginning of the second layer is located in the outer part of the disc, so the drive starts reading from the outer tracks towards the inner part of the disc. Again in this case, the max supported speed is 12X for the Plextor and Asus drives, with the later being the faster even though the speed differences are negligible.
With write once media, DVD±R, the NEC drive reported the fastest reading speed. Using DVD±RW media, the Plextor drive reported the fastest reading speeds with an impressive 9.02X average in both cases. Very steady performance from the PX-716AL.
