Writing Quality Tests of AOpen CRW3248

We used many media ,mostly 24x certified, and burned them at various recording speeds with AOpen CRW3248. We used Nero 5.5.7.2 as the CDR software. The produced CDs, were measured from DigitalDrives and results are illustrated in the following tables. Note that almost all CDs were written with JustSpeed DISABLED:

The AOpen CRW3248 shows a good behaviour at the 32x recording speed, mostly with TaiyoYuden 74min CDs. The drive seems not to have a stable performance with 80min CDs. In several cases produced a high C1 error rate and even C2 errors. Remember that the drive's firmware is still under 1.0 revision. Newer firmware updates could improve media compatibility.
