I've never heard anything so loud from a computer (save music), this is mainly when writing at max speed, its a very loud vibrating disk sound as though the disk is spinning off axis?
 
Optical drives are always loud when at full speed. Not much of a way around it. It's a cheap and easily replaced part, I wouldn't loose sleep over it.
 
I still remember the custom PC I built 7 years ago and the PC I had before that. Their optical drives were both really loud. I haven't received my Mac Pro yet, but I guess it's normal for desktop drives to be this loud. My MacBook Pro's optical drive was really quiet in comparison.
 
The 27" i7 iMac I sent back was so quiet, isn't it the same drive? If the slot loader is so quiet why bother with the drawer version in the pro?

Tray-loaders are less picky about disc type. Also, the drives in the Mac Pro are full height, meaning they're cheaper and faster.
 
I actually think it's about half as loud as my 2008 MP drive, that thing was LOUD. 2010 is much quieter.
 
I have used my 6-core MP optical drive with approximately 10-12 discs, but it has only produced strange sounds when installing software off of 2 discs (1 CD, and 1 DVD).

I've experienced this with my G5; most discs seem normal, yet a rare few discs make quite a racket. The first time it happened on my G5, I tried the disc on another machine, and it made no noise.

Why would some discs make noise on one machine, but not another machine?

Don't know but I have seen osx install disks do that on mac minis> I mod a lot of them
 
Standard DVD drives (without special noise reducing features) are loud, that's normal. When reading at 16x, the DVDs in your drive spin faster than a hard drive! 10k+ RPM cannot be silent...

I had a disc actually explode in an external DVD drive once. It sounded like someone hit my disc with a hammer. Dumped a zillion bits of disc out and the drive still works fine to this day.
 
What do you guys mean by noise. AS when I play dvd's in my new mac pro it has a rattle? almost like the disc is rubbing? ive had this with a discs ive tried is this normal ?

Its not what i expected from such an expensive computer?
 
The drive rattles when it is spinning slowly (around 1x speed when watching DVDs). I think this noise comes from the low motor duty cycle and is nothing o worry about.
When the disc is spinning fast, a more wind-like noise is caused by air vortices.
