Verbatim DVD-RW 2x

That’s another “native” Verbatim, manufactured by Mitsubishi Chemical Corp.

You can see from the diagrams that the quality of the disc is high. The maximums of PI errors and failures are far below the limit as set by the standards. The overall appearance of the diagrams testifies to the stability of the operational layer of the disc. This is a very good medium, if you’re satisfied with the relatively low burn speed it supports.

Verbatim DVD-R 8x

The last Verbatim we tested during this session is also a product of Mitsubishi Chemical Corp.

This DVD-R can hardly be characterized as a quality product, though. The spikes of PI errors and failures are two times above the highest acceptable value. As you can see, the problem lies in the beginning of the disc – the quality of this zone is much worse than the rest of the medium. Considering this, we don’t recommend this disc to you. But it is quite possible that the problem zone is a defect of the particular sample of the disc we tested.

XIDEX DVD+R 8x

The disc selling under the XIDEX brand proved to be a product of CMC Magnetics Corp.

Nero CD-DVD Speed couldn’t read the written disc; KProbe did the reading, although with some visible effort. The diagram above shows you the reason: the maximums of PI errors and failures are far above any norm, especially the failures. Money you are asked to pay for this medium should be spent for some better purposes instead. Thumbs down to this one.
