- Writing Performance

TDK 880N supports DVD-R/RW and DVD+R/RW writing. The maximum supported speed for DVD+R and DVD-R is 8x Z-CLV and 4x CLV for DVD+/-RW media.

8x DVD+R

An 8x DVD+R disc from CMC Magnetics was used to check the 8x writing strategy of the drive. The software used was Nero CDSpeed, with its "create disc" function.

The drive started the writing at 4.13x, maintaining this speed until the 800MB address mark on the disc, where the drive stepped up to 6x until 2.20GB. At this point we experienced an other step up to 8x writing for the rest of the recording (hence the Z-CLV mode). The average speed is 6.80x.

CMC 8x DVD-R

The simulation with the 8x DVD-R was almost the same with the 8xDVD+R one. In this test we used Mitsubishi Chemicals media.

- Burning Tests

The best recording times are illustrated in the following table. The values were taken after burning 4315MB of data on various DVD±R, DVD±RW media, using the maximum allowed writing speed for each disc. For comparison, we also include the writing times for the Pioneer DVR-107D and Nec ND-2500A.

With the DVD-R/RW media, TDK wasn't the fastest. However the reported recordings times for DVD+R/RW were at an average level as expected, due to the average 6,80x speed for this format.

The table below presents the writing speeds, media name and media code for the various discs used.

Although TY and Maxell DVD+R have the same ID, were burned in different speeds. Below are the screenshots from Nero:

- Packet Writing Tests

For this test we copied a 403 MB file (412.822 KB) from the hard disk (on the same PC as the recorder) to the formatted RW media through Windows explorer (drag and drop).
