RW Writing Tests

The supported writing speeds for the HS-RW format are the 4X, 8X, 10X, 12X and 16X (CLV).

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.

The TEAC CD-W548E ends the task at 5:00mins. The same time is needed from the ASUS CRW4816A. The Plextor PX-W4824A is the faster drive due to its US-RW re-writing speed. The SONY CRX-210E1 is the slowest drive since it supports the 12X speed.

- Packet Writing Tests

We used Ahead InCD v3.51.61 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.

The TEAC drive performed quite well with a 12.16X writing and 12.3X reading speed under the packet-writing mode. The PleXWriter PX-W4824A gets the first place; due to increased 24X US-RW supported writing speed, while the SONY CRX-210E1 leads in the reading process with 20.45X.

- Mt. Rainier Tests

For testing the Mt. Rainier performance, we used was InCD v3.51.61 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. While we could perform the writing/reading tasks, the drive couldn't eject the media and locked. We had to reboot in order to remove the disc. This should be looked from TEAC engineers and fixed with a future firmware upgrade.

- EasyWrite tests

The Philips Easy Write tests checks the quality level of the Mt Rainier implementation. The drive accepted the EasyWrite test suite commands however failed to eject the media, as with the tests with the InCD software...
