7200rpm drives are much louder (noiser) than 5400rpm drives-period. I've owned 2 7200rpm IBM's and a Quantum and they all clatter like the old "bouncing ball" Selectric typewriters when reading/writing. Question: Does anyone have hands-on experience with Ultra 100 verses Ultra 66 at equal rpm's?
HDD: Are Ultra 100's louder than Ultra 66's?

Is PC133 more loud than PC100? 
I wouldn't worry about it. Considering drives can't even reach the limits of ATA66, I wouldn't expect any more NOISE from them. It pretty much means if you have a couple of drives on one channel, they'll have more room to breathe.
And my 7200RPM Maxtor is almost silent compared to a 5400 maxtor and 2 5400 WD's I have.

If the two drives were equal in everyway bar U1000 vs U66 then I guarantee the noise difference would be non-existent.
The only change in noise levels is going to be due to newer (U100) models vs older (U66) models.
Newer drives will have greater areal density on the platters than older drives. Hence if you get one of the same capacity it will (generally) use fewer patters than the equivalently sized U66 drive.
fewer platters = less noise (U100 wins for same size)
For example a 15 or 30GB IBM 75GXP (1 platter) is considerably noiser than a 60 or 75 GB one (3 platters).
Also newer drives will use superior manufacturing techniques and tolerances which should make a quieter drive.
So no, U100 drives will if anythign be quieter than a U66 drive (generally).
You will however find out that individual drives of identical models can vary in loudness quite a bit.
Good luck!

My ata100 drive is so quiet I wonder if it working sometimes or if I locked up (see below). It's not the ata that decides it. It's the make/model.
I do have both and the 100's are QUIETER period. The new IBM's have a floating head in which never touches the platter, making for a quieter drive.
Depending on the drive itself... I know I have seend 10gb 5400 rpm drives that were Alot Louder than my 30 gb. 75gxp
Billyjak,
The drive heads never touch the platter on any of my hard drives. You must get a lot of broken HDs.

ATA66 and ATA100 are electronic standards, not mechanical issues. 7200RPM vs 5400RPM is an issue with moving parts, ATA100 isn't. Newer drives are much quieter than older drives, even the 10000RPM Atlas 10K 2 here at work is only a little louder than my old 5200 RPM Maxtor 8GB.
Thanks Guys 'n Gals. Based on your inputs I took the leap for an IBM 75GXP 30 gig and it turns out that it is indeed quiet. So it boils down to selection by make AND model. Thanks again, you're all great!
Yeah Danzl you were right your generalisation wasn't sound!
My HD IBM 22XGP is quite quiet compared to my Fujitsu 3.2gb. Some makers have a deader sound, some drives are more resonant (not good).

& If you really wanna make that 75 gxp quiet than disconnect the HD LED & you wont hear anything at all... I Dont
7200 rpm drives are nosier than 5200 rpm... I beg to differ.
I have two of those drives in my system right now. The 7200 rpm is my IBM 75GXP 45GB drive and the 5400rpm one is a Western Digital Caviar 27GB. The WD is much louder than my 75GXP. I have my 75GXP on a Promise Ultra100 controller right now and the noise level during access is even decreased when on that controller... not to mention less heat. It comes to a point where I can't hear anything at all. I even have a side of my case always opened so...

The controller interface on the hard drive is not going to change how loud a drive is. I had a coworker who used to swap controller interfaces on hard drives if it saved him money. Our boss let him take home dead hard drives from work and he collected the controller boards so that he could convert drives to other interfaces.
Everything from RPM, access time, number of platters, manufacturer, model, OS/caching to the specific drive is going to make a difference in how loud it is.
Shudder's analogy almost works IMO, except that neither PC100 or PC133 make any noise that can be heard by the human ear.
