The AOpen CRW5224 writing quality cannot be judged at this point due to beta firmware revision (0.91). The above-posted results give a first look. The drive seems to like most the Prodisc, Ciba Plasmon and partially the Octron (Ritek) media.
We did notice a bad behaviour with TaiyoYuden and especially with Mitsubishi Chemicals 48X certified media. The recording times vary according to if JustSpeed is enabled or disabled. With the Ciba Plasmon 48X media, we had the best results of 2:29mins.
- C1/C2 Error rate from CibaPlasmon 80min 48X @ 52X (JustSpeed On)
- C1/C2 Error rate from Taiyo Yuden 80min 32X @ 24X (JustSpeed On)
- Firmware 0.95

The AOpen CRW5224 writing quality was improved with many media, while became more strict with the inserted media. Now the Ciba Plasmon 48X and TY 32X (and 48X) media cannot be written at 52X with JustSpeed On. The best improvement is the writing with Mitsubishi Chemicals 48X media. The drive seems not to handle Prodisc media very well at the last minutes where 50X~51X reached.
- C1/C2 Error rate from Prodisc 80min 40X @ 52X (JustSpeed On)
- C1/C2 Error rate from Prodisc 80min 40X @ 52X (JustSpeed Off)
- C1/C2 Error rate from Taiyo Yuden 80min 32X @ 52X (JustSpeed Off)
We also noted some problems with specific media. In those cases the drive will stop burning when writing speed exceeds one specific limit as the following Nero screenshots show
- Imation 48X media
- TDK D-View 24X media
In the following table you can see the manufacturing details of the media we used for our tests.
