"Btw, I was surprised by the drive's audio extraction speed. It reads out Audio CDs @48x and the quality is excellent."

"I use EAC myself, and never had a problem with this drive, both in burst and secure mode. This is a very good DAE drive, regardless of the caching."
I tested it 5 minutes ago (only for you ) with CloneCD 5.1 on the CD "The diary of Alicia Keys" which is protected with Cactus Data Shield 200 5.00.150.
(Although it was slow....)
Cannot say more about this since I use the Plextor Premium for ripping/copying audio.
Hope this helps...
