Aopen DRW8800/AAN - Page 12

KProbe PI/PO quality results

The following screenshots show the PI/PO scans for various DVD-/+R and DVD-/+RW media, recorded with Aopen dual 8x8 at the maximum permitted speed.

The software used for the measurements was KProbe v1.1.28, the ECC was set to 8 and the reader was LiteOn LDW-811s. The specific methodology is very dependent on the drive used as a reader, while the reliability of the PI/PO provided output is also not technically confirmed. Hence, we cannot safely come up with conclusive results, although we do make a comparison of the drive behavior when using various DVD recordable/rewritable media.

The recordable discs we used, came from Verbatim, Taiyo Yuden, CMC, MAM, Maxell , MC and Ritek. Further details about each disc type are presented at the bottom of this page.

  • Kagaku DVD+R 8x (Recorded at 8x)

  • Thats 8x DVD+R (Recorded at 8x)

  • Philips 8x DVD+R (Recorded at 8x)

  • That's 8x DVD-R (Recorded at 8x)

  • MCC 4x DVD-R (Recorded at 8x)

  • Verbatim 8x DVD-R (Recorded at 8x)

  • TY 4x DVD-R (Recorded at 8x)

  • Maxell 4x DVD+RW (Recorded at 4x)

  • Kagaku 4x DVD-RW (Recorded at 4x)

Kprobe awards the Aopen drive with quality results. From the screenshots above we can see that all media used for the quality measurement, returned good PI/PO levels. However the values are slightly increased at the end of each disc but still acceptable for both DVD+R and DVD-R formats, even from media that are certified for slower speed writing.
