Right below the picture of the drive on the box there are white letters that read some thing like this:
"picture is representational only"
When I bought my IOmagic 48x16x24x, the drive inside the box looked nothing like the drive on the box.
It could be BENQ, but it also could be optorite, yes they have a 52x burner.
If I wore you I would go to iomagic support forums too see what drives people are getting. Or call thier tech support they might just tell you.
LITEON is the only way to go.
