HS-RW / Packet Writing Tests

- HS-RW Writing Tests

As we described in our introduction of each drive, the CyberDrive CW078D supports 16x writing speed, while all the rest drives 12x. As expected the CyberDrive CW078D is the faster re-writer with 306secs. The TDK CyClone drive comes second with 404secs and Samsung SW-240B last with 411secs.

- Packet Writing Tests

We used Ahead InCD v3.28 for the packet writing tests. The CyberDrive CW078D was tested with bulked 16x certied media and the rest drives with normal 4-10x media from Verbatim. The formatted disc had 534mbs 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 twice to eliminate any possible time measurement faults and user errors:

The CyberDrive CW078D is the faster re-writer under packet writing format. The average writing speed is 11.45X, while other drives stay at 8.65X. The WAITEC Storm40 had the lower writing and reading performance with 7.09X. The faster reader under packet writing format is the TDK drive with 23.02X, while CyberDrive follows with 11.45X.

- Mt. Rainier Tests

For testing the Mt. Rainier performance of the Mitsumi CR-485C and TDK CyClone 401248B, we performed two types of tests. The software we used was WriteCD-RW! by Software Architects.

First Test

After the format process, we immediately start the recording process (drag & drop). When the drive finishes, we start the reading process back to the HD. At this mode, the drive writes, reads the quality of the written data and background formats the disc at the same time. The recording performance of each drive is displayed in the below table:

The results with both drives are totally different. The Mitsumi CR-485C has the lowest writing performance, while the TDK CyClone 401248B doesn't seem to work correctly since the recording speed is not according to wha the rest drives can give.

Second Test

At the second test, we left the drive alone to complete the background formatting and afterwards, we repeated the above tests. The recording/reading performance in this case is higher for all the drives, since now only record & read are performed. The disc has been scanned for bad sectors during the format process:

The TDK CyClone 401248B continues to have the higher reading/recording speeds than other drives. The Mitsumi CR-485C follows, while the rest drives that support Mt. Rainier stay behind.
