Anyone knows details of SONY DRU-815A?

DRU-815A, a rebadged Lite-On SHW-1635S or SHW-16H5S?
Anyone knows?

I’d say it’s the 1635S, but there’s no information available on this drive.
Google returns 15 results!

i don’t see the point of this drive, they have just released the 810, and from that i would imagine the 815 would be an oem benq again
