Since easy-going-man asked me for details of this DVD-ROM in a different thread, and since I don’t want to ruin that thread with off-topic posts, I thought that it is a good idea to start a new thread about this drive.
CDBremse does not work with the drive (yet).
It is one of the fastest drives on the market atm. c’t magazine tested DVD-Rom drives a few weeks ago (08/2004 issue), and the Aopen was the fastest drive in almost all categories (all DVD and CD formats). See if you can get that issue (if you don’t have it already), it’s a very detailed (typical c’t) review.
A few transfer rate scans:
DVD+R (DVD-ROM booktype, not a full disc):
With the DVD-ROM booktype, all discs are read at full 16x speed, basically treated like pressed SL discs. Without this booktype, the speed is (artificially) reduced for recordable media to prevent the disc from exploding in the drive (precautionary measure, not really necessary IMHO), as can be seen in the next DVD-R scan:
All DVD-ROMs on the market reduce the reading speed a little for recordable media. The only way to enable full speed reading is either to use DVD+R discs with the DVD-ROM booktype, or modified / hacked firmware, so called “speedpatches”. TDB released some speedpatched firmware for the LiteOn 166s. In principle, it should be possible to release similar firmware for the Aopen drive.
The NEC 3500A is the only drive I know that reads recordable (non rewriteable) media at full speed regardless of the booktype.
This is very fast for rewriteable DVD media. The NEC 3500 is quite a bit slower. I wonder how fast the drive would read these discs with the DVD-ROM booktype. Can’t test that yet though, since the TDB / Herrie firmware does not allow DVD+RW booktype changing (yet).
DVD9 CSS protected disc:
Quite fast as well. It should hit the 13x mark with a full DVD-9 disc. The NEC 3500A is considerably slower.
No comment needed I guess.
