CD Recording Tests

- CD-R Writing Tests

The NEC ND-2500A supports 4x, 8x, 16x, 24x and 32x writing speeds. Below is the CDSpeed writing simulation graph with Taiyo Yuden 48x CD-R media.

The simulation test under Nero CD Speed confirmed the manufacturers specifications for 32x recording which uses Z-CLV. The average speed was 27.43x.

- Recording Times

We created an 80min data compilation with Nero Burning Rom and recorded it on a 700MB disc. The NEC drive returned a time of 3:39 minutes, with 32x writing speed selected, which is a very good time (for 32x). The Pioneer drive, due to its 24x supported writng speed, was slower at 4:49 minutes.

Below are the best writing times for the Nec ND-2500A drive at 4x, 8x, 16x, 24x and 32x with a Taiyo Yuden media.

In the following graph you can see the recording times with various media brands.

- CD-RW Writing Tests

The NEC ND-2500A supports 16x CLV maximum rewriting speed, with Ultra Speed rewritable media. Below are the results from the CDSpeed writing simulation test with blank 24x US-RW media from Mitsubishi Chemicals.

The test confirmed the drives specifications for 16x rewriting. The burning procedure started at 16.01x and finished at 16.44x having an average speed of 16.02x.

For comparison, we provide the rewriting times of the NEC and Pioneer drives.

We also used Nero Burning Rom software to burn a data disc using 24x US-RW media from Mitsubishi Chemicals. The data compilation burnt, had a size of 651 MB. The duration of the recording process was 5:11 minutes for NEC and 4:01minutes for the Pioneer.

- Packet Writing Tests

Using InCD and Mitsubishi Chemicals 24x US-RW media for all Packet Writing tests, quick format took 37sec. The formatted disc had 530mbs of free space. We copied a 403 MB file (412.822 KB) from Hard Disk (on the same PC as the recorder) to the formatted RW media through Windows explorer (drag and drop).
