I was hoping I wouldn't see this:
"Plextor uses again Zone-CLV as the main recording technology and at the maximum 40x speed, with the use of 80min CD, the total recording time drops down to 179sec! 
The 40x recording speed is reached by 4 steps: The drive starts writing at 20x, rises up to 24x, rises up to 32x and last reaches 40x. The 40x writing speed is reached at 54mins, when using 80minCD"
Probably another zone drive that will only be about 10-20 seconds faster than a 24x rated non "zone-clv" drive.
Anyway, I'm glad that I kept my Kenwood 72X trueX drive for disc to disc copies!
