DVD+R Double Layer writing performance:
The specifications of this drive tell us that it should write DVD+R DL at 8x.
We used Nero CD-DVD Speed to create a data disc with the ND-4570A, and then used the Lite-On SHW-16H5S along with Nero CD-DVD Speed 'Disc Quality Check" to scan our disc.




The NEC ND-4570A used Z-CLV, (Zone-Constant Linear Velocity) to write DVD+R DL at 8x. This gives an average writing speed of 6.56x, and a writing time of 18 minutes and 33 seconds. The result is good. (Thanks to SVP UK for sending us this media).

This concludes our preview of the NEC ND-4570A drive. Let us head on to the final page for our 'preview" conclusion…..

Disk-Quality score with MCC 004 at 84%
and wit MCC 003 at 70% is somenthing NOT acceptable for me!




Best quality Verbatim discs show lots of errors and jitter on this drive causing Nero Speed 4.7 to give a Disc Quality score of ZERO.
Same discs have a score of 94 and no jitter errors when burned on my ND 3520A.
AVOID THIS BURNER!!!



I THINK THIS DVD-RW, CD-RW etc is very good!
