BenQ DW822A 8X Dual - 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 BenQ 8x Dual writer at the maximum permitted speed.

The software used for the measurements was KProbe v1.1.29, the ECC was set to 8 and the reading at 4x with reader the 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 Thats, CMC, Philips, Maxell , MC and Ritek. Further details about each disc type are presented at the bottom of this page.

Kprobe reported quite acceptable PI/PO mesurements for all written media with the BenQ writer. Although all +R media were written at fast times, it was quality writing and they were fully readable.
