CDR Tests
The CRW-F1DX series support 1X, 4X, 8X, 16X (CLV) and 44X (CAV) writing speeds. When OWSC (Optimum Writing Control ) is enabled, the drive will select automatically the best maximum possible recording speed from 8X, 16X (CLV), 20X, 24X, 32X, 36X, 40X and 44X (CAV). You cannot select the speeds between 16X and 44X.
The Optimum Writing Control system, determines the optimum writing speed for the disc inserted. The feature can be disabled through Nero software, and as a result, user will be able to record all inserted media at the maximum speed (44X). With OWSC on/off, you can select all recording speeds (1X-44X). When OWSC in enabled and a low quality media is used, Nero will report the drop of recording speed, usually down to 16X:
The complete list of the supported media for the various speeds can be found at http://www.yamaha.co.jp/english/product/computer/discf1.html.
- Full CAV recording method
Using an 80min disc, we can see the drive's start, ending recording speeds, according to the Nero CD Speed software. The drive starts writing at 19.68X and gradually reaches almost 44X at the end of an 80min disc:
The drive also supports 40X P-CAV writing speed that reaches up to 32.99 X average writing speed:
- Recording Tests
YAMAHA CRW-F1DX finished the writing process in 3:07 minutes. The result came with the IEEE1394 interface, with Sanyo Digital 80min 24X media. With USB2.0 interface the best result we had was 3:08mins. The drive is equal fast in both IEEE1394/USB2.0 interfaces. The YAMAHA CRW-F1E was faster in our tests by 4secs and CyberDrive CW088D leads the race at 48X with 156 seconds.
Below is the screenshot of the best recording result:
With USB 2.0 interface, the best results we had are about 3:08mins:

The drive can overburn up to 99mins without any problems.
- CD-Text Results
The drive can read/write CD-Text without any problems.
- CloneCD Writing Tests
The CloneCD software reports that the drive supports the DAO-RAW feature. With the use of proper media, DAO-RAW writing can be performed up to 44X (CAV). CloneCD doesn't offer any option to disable OWSC. For checking the drive's EFM correction status, we used 3 different game titles with various SafeDisc 2 versions. For getting the maximum of them, we used the latest software patches. We used the Yamaha CRW-F1DX both as reader/writer at maximum reading/recording speed. We burned two discs for each game (Amplify Weak Sectors On/Off) and the results are posted in the below table:

As the test results showed, the CRWF1DX drive can backup up to SD2 v2.50.020 version without the need of Amplify Weak Sectors. However with the latest v2.51.021+ builds it will not produce 100% correct playback disc. The backup media worked only in the LiteOn LTR-32123S recorder (with Hide CD-R activated) and the YAMAHA CRWF1-DX.
