BTC 5224IM IDE CD-RW RECORDER - Page 9

RW Writing Tests

The drive supports the 12X, 16X and 24X US-RW and the 4X, 8X, 10X for the HS-RW format.

For the burning tests, we burned a full 74mins disc with all the drives. The results are showed in the following chart. We used the maximum supported speed for each drive.

Although the BTC 5224IM supports 24X rewriting, the drive did not work with Mitsubishi Chemicals US-RW (24X) based media. It only allowed rewriting at 16X, hence the increased writing times in the above graph (299 seconds). The CyberDrive and Asus drives are faster with 219 seconds (24X).

- Packet Writing Tests

We used Ahead InCD v3.51.91 for the packet writing tests. The formatted disc had 534 MB of free space. We copied a 403 MB file (403.147 kbs) from a Hard Disk (on the same PC as the writers) to the formatted RW media using Windows Explorer (we dragged and dropped) and we completed the test more than once, to eliminate any possible time measurement faults and user errors.

Again, the BTC drive behaved as a 16X recorder and gets the last place with a 10.85X average writing speed. In the reading part, the performance was not higher compared to the other drives.

- Mt. Rainier Tests

For testing the Mt. Rainier performance, we used was InCD v3.51.91 by Ahead Software. After the format process, we immediately started the recording process (drag & drop). When the drive finished, we started the reading process back to the HD. The PX-W4012TS performed well without any problems. The drive's reading/writing performance was lower than in the normal Packet writing mode.

- EasyWrite tests

The Philips Easy Write test checks the quality level of the Mt Rainier implementation. Although the drive accepted the EasyWrite test suite commands it didn't fulfil the basic PartA v1.60 tests, so we didn't proceed with the rest tests.
