[QUOTE=mciahel;2070714]Hi,Liteon is using Cypress AT2 chipset for their retail external units.
I was able to get full speed (16x) with my Liteon SHW-165P6S in a AT2 based enclosure.
With other drives I tested (Philips 1660P1, Samsung 182D), 12x is fine. The only drives, that don’t like the AT2, is my Pioneer 112 and LG4163 (but this hates being installed externally in general).
Is AT2 chipset USB or IEEE1394a?
Anyways, as an update to my current ext encl setup, my LiteOn drive is registering 28MB/s peak burst TRT based on CDSpeed readings.
When I use DVDFab to do a backup of an entire DVD, it usually takes 25-30mins to get the ISO image. Then, it takes 5 mins to burn to a DVD-R.
Does that sound normal?
