CD Recording Tests

- CD-R Writing Tests

Philips DVDR824P supports 8x, 12x, 16x and the maximum 24x P-CAV writing speeds. Below you can see the CDSpeed writing simulation graph with Taiyo Yuden 48x CD-R media.

The writing speed in the beginning of the disc is 18.21x and increases until the 14:00:00 address of the disc approximately, where it reaches the maximum 24x. According to CDSpeed, the average writing speed with a 80min disc is 23.53x.

The Philips dynamic calibration system is responsible for the small peaks of the transfer rate graph. The feature calibrates the writing speed in real time during writing to ensure quality burnings.

- Recording Times

For the burning tests we created a 80min data compilation through Nero Burning Rom recorded the data on a 700MB disc. Philips DVDR824P finished the task in 4:05 minutes, when we selected the 24x writing speed. The performance is adequate for the 24x recording speed. Note that the Plextor drive is faster since it offers 40x CD-R writing.

Below you can see the best writing times of Philips DVDR824P at 8x, 16x, and 24x. In each case, the Seamless Link feature was enabled:

- CD-RW Writing Tests

Philips DVDR824P supports the 10x CLV maximum rewriting speed, with High Speed rewritable media. The drive also writes at 4x CLV with NS CD-RW. Below you can see the CDSpeed writing simulation test with blank 10x HS-RW media by Ricoh.

We used Nero Burning Rom in order to burn a data disc with HS-RW media by Ricoh. The data compilation we burned had a size of 651 MB and the duration of the recording process with Philips DVDR824P was 8:03 minutes (10x). The best rewriting times for all the drives are illustrated below.

- Packet Writing Tests

We used InCD and Mitsubishi Chemicals 10x HS-RW media for all packet writing tests. The quick formatting of the media took 32sec. The formatted disc had 530mbs of free space. We copied a 403 MB file (403.147 KB) from a Hard Disk (on the same PC as the writers) to the formatted RW media through the Windows explorer (drag and drop).

Philips drive gave an average writing speed of 6.46x and the writing process finished after 6:56min, which is a slow time due to the competition.
