I've recently bought a Plextor PleXCombo PX-320A DVD/CD-RW drive, and I have to admit I'm quite pleased with it. The drive is relatively quiet when reading, and performance is quite acceptable, a huge improvement over my old PleXWriter 4/2/20 drive.
OTOH, I've had both a 48X CD-R and a DVD drive that took ages to get up to speed and sounded like jet aircraft taking off.
It depends on the drive. Not all new/fast drives are bad, and not all of them are good.
