Plextor PX-716SA offers 6X writing support for both DL formats.

For our tests this time, we chose the "Create Data Disc" feature of the CDSpeed utility. The reason for this is that we wanted to fully burn the DL media instead of just the 6.86GB we usually used.

Now let's take a look at the writing strategy for both +R and -R DL.

- DVD+R DL

This disc is the new DVD+R DL from Mitsubishi Chemicals, certified for 8X, with ID MKM 003. There are not many drives that support this media for 6X or 8X at this moment. The Plextor PX-716SA managed to start the writing task at 6X but after 5Gb of recording, it lowered the speed to 4X. The total time needed was 22:06min.

The specific media comes from Traxdata, with id RITEK D01 and is certified for 2.4X recording. Our Plextor PX-716SA managed to burn it at 4X with a time of 28:40min!!!

- DVD-R DL

Certified 6X DVD-R DL from Mitsubishi Chemicals, MKM01RD30. The PX-716SA burned it in 19:06min confirming its 6X DVD-R DL support.

This is new DVD-R DL media from Traxdata, certified for 4X writing, with id RITEK P01. The Plextor PX-716SA burned it at its certified speed of 4X in 27:29min. Note that not many drives at the time of this review, support 4X with this specific media.
