CDSpeed/PlexTools Scans - Page 6

In order to test the writing quality and readability of the burned media we used two readers with two software applications:

• The LiteON SOHD-167T with patched firmware being able to read DVD5 up to 16X CAV and DVD9 up to 10X CAV. For the transfer rate tests we used the latest Nero CDSpeed version.
• The Plextor PX-712A with the latest available firmware. For scanning the disc, we used the latest PlexTools version at 2X CLV reading speed, BURST mode, with middle accuracy.

In general, a "perfect" disc should have a smooth reading curve, very low PIE/POE and zero (0) POF error rates. Most times however, even though a disc has very low PIE/POE error rates, the reading curve may not be smooth containing dropoffs. Due to the fact that we oversped the reading capabilities of the LiteON SOHD-167T, such drops are expected, especially near the outer area of the disc.

The measurements below should be taken not as the absolute criteria of the burning quality, but as an indication level.

4X DVD+R Writing Speed

• BeALL 4X DVD+R @ 4X

• BeALL 8X DVD+R @ 4X

• BenQ 4X DVD+R @ 4X

• InfoSmart 4X DVD+R @ 4X

• Maxell 4X DVD+R @ 4X

• MKM 4X DVD+R @ 4X

• Optodisc 4X DVD+R @ 4X

• Samsung 8X DVD+R @ 4X

• SKC 4X DVD+R @ 4X

• Traxdata 4X DVD+R @ 4X

- Summary

Although Infosmart media gave the worst quality scan, there were no PO failures with any disc, and most media performance was more than satisfactory. The good news about this drive is that it produces good quality burns with most of the media, at different speeds, although speed is reduced compared with other 8X burners.
