Mt. Rainier Tests

- InCD Tests

For testing the Mt. Rainier performance, we used was InCD v3.15.16 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 AOpen CRW5224 performed very low since the writing taken up to 28mins, while the reading performed at full speed...
