A burn quality test in my BenQ drive

PI errors start at about 10 reducing to well under 10 until the 4 gig point when these errors rise to a maximum of just under 30.

Jitter remains well under 10 except for the outer edge

PIF is negligible peaking at 10 at the outer edge

Good results all round here

Speed test in the Toshiba drive

This scan shows a near perfect graph. What more can I say?

A burn quality test in my BenQ drive

PI never rose above 20 with jitter constant averaging just under 10%

PIF again negligible peaking at just over 10

Again we have a good all round result

Speed test in the Toshiba drive

Slight dip around the 3 gig point coinciding with the peaks in the PI/PIF charts but nothing to worry about and playback is not affected

Burn quality as tested in the BenQ drive

Excellent PI with a peak of 8 and PIF peaking at 6,

Jitter averaged 9.5 although for some unknown reason the graph was not drawn

They don’t come much better than this

Speed test in the Toshiba drive

This scan shows an almost perfect graph again What more can I say?

Burn quality as tested in the BenQ drive

After a good start the PI errors increased as the burning speed increased and rose to an unacceptable level of over 300 during the latter part of the scan. PIF remained below 10 for the duration of the scan

Jitter started at 10% with a sharp increase at the first burn speed increase slight increase at the second burn speed increase peaking at 13.9% with an average of 11.7%

PI & Jitter are high and unacceptable

Speed test in the Toshiba drive

This scan shows a near perfect graph.

The disc is perfectly readable without errors and although the PI/Jitter tests could have been better the disc played OK without problems

Burn quality as tested in the BenQ drive

PI peaking at just over 20 with an average of 5 Jitter starting about 8% raising gradually to a max of 11% averaging 9.1%

PIF errors too few to mention

Another very good result with this drive

Speed test in the Toshiba drive

This scan shows a near perfect graph. and there is nothing more to say

Burn quality as tested in the BenQ drive

PI errors Very High starting at about 160 reducing in the middle of the scan but rising again to peak at around 300 at the outer edge

Jitter starts high at nearly 15% remaining above 12% for the entire scan with an average of 13%

PIF is about 5 at the beginning of the scan with some peaks of up to 30

Not a very impressive result

Speed test in the Toshiba drive

Again no problems here at reading the disc

The errors in the other scan do not seem to have affected the readability of the disc

Burn quality as tested in the BenQ drive

PI starting about 20 reducing at the first burn speed increase and remaining constant up to 3.5 gig where the errors increase up to a peak of 150 at the outer edge.

Jitter starts at just above 10% dropping to 10% at the first speed increase and again dropping at the second burn speed increase gradually rising to the outer edge. The jitter average is OK at 9.4%.

PIF errors are minimum

Speed test in the Toshiba drive

This scan shows a good graph up to 4 gig dropping off slightly after this point.

Burn quality as tested in the BenQ drive

The PI readings are so low here that the graphs scale remained at its lowest of 0-10. Jitter well under 10% averaging 8.1% with PIF again negligible

If only all graphs were as good as these
