Q: I have a SCSI disk subsystem, a 15K disk drives OS supported by 10K (all first generation, and I think warrentee). The 15K drive is weird lately includes making a high pitch whine ~ 5min after startup. This sounds produced wailing electric, mechanical, and not in the 10-15kHz range, but it goes away. Thats just an annoyance, but sometimes my whole machine starts to vibrate and loud. If I give it a good whack, it stops (reminiscent smackin the TV to work).
So, it looks like a replacement is in order and soon. I see a few courses of action:
1) Buy a Raptor and ditch the SCSI (complete storage requirements as needed)
2) another drive to maintain 15K my trusted performance
3) a Barracuda buy and make the box very quietly, performance to sacrifice buying less noise
I not particularly like noise, but I put up with the HDD noise performance as a necessary evil. The rest of the box is pretty darn quiet. Will go back to 7200 or 10K rpm drives me mad?
What I do u003c200 U.S. dollars based on the budget?

try getting some rubber washers and putting them between the hard drives and their mounts. its a common practice.
I have the SLK3700AMB case so the vibrations even defeat the rubber mounts.
As for warrentee, the 15K drive case is a Seagate, but badged as a Compaq drive. I was under the impression that I was SOL trying to get a warrentee from Compaq. If someone knows otherwise, please LMK.
(the 10K drive is still under warrentee, but it's doin' just fine)
OH yes, and I've experienced the data-loss horrors of RAID 0 and won't go back. The performance boost (which is real-world negligable IMHO) is not worth the risk of failure.

Re:Consider a pair of 80 gig Seagate 7200.7 drives and put them in RAID-0. Cheap silent and good performance.

When you kick and the sound goes away, that sure doesn;t sound like a SCSI drive to me. I would try to isolate where the noise is other than the high pitched whine. SCSI drives have a very high MTBF, and that would be the last thing I suggest. Also, if you are used to a 15k SCSI drive, even the raptor will seem slow. (IMO) Stay with SCSI, but make sure that the problem first. You can get a long SCSI cable (unlike IDE or SATA) and plug the drive power into an old AT PSU, and then you will know for sure where the moise is coming from. Mine are 6 feet away in an old 486 CASE.
Also, since SCSI devices have such a high MTBF they have at least 5 years of warranty – are you sure it's expired? Other than that, go for the Raptors. Best investment I ever made in my machine.

You make good points and this is something about which I am concerned. I know the Raptor is speedy crazy-fast, but it's still only 10K rpm. The transfer rates are much faster than my current drive, I'm sure, but the seek times on a 15K drive are terrific. I don't want to drop a pile of cash on a premium HDD and be disappointed.
Has anyone had first-hand experience with 15K drives and Raptors to give a 'feel' comparison?
As far as isolating the source of vibration, I had the same gut feeling as you did. I thought it must be a fan or something similar. All of my fans are on controllers so when the vibration started, I killed all the fans. Sound stayed. My HDDs are in a removable cage to I did just that – removed it and then unplugged all but the 15K drive. I'm 99% sure it's that drive that's making the vibration but it doesn't do it all the time which is the strangest part.
Killer idea on making the HDD remote. I really have to look into that – stash 'em under the bed or something similar.

Re:Looks like the Raptor is the way to go then, although the 74G is a little more than I wanted to spend. Meh, I'll just have to sell off some of my junk. FS/ST I go.

Re:Ditto on the Raptor 72. I have two 36's are they're f**king awesome… and the 72's are even better from what I hear.
Re:I'd go Raptor as well. I'm waiting for a hot Sonata deal so I can make room to put another one in for a RAID-0 and a well overdue complete format\reinstall.
Re:Raptor kicks the butts of all drives listed at StorageReview.com (http://storagereview.com/php/benchmark/compare_rtg_2001.php?typeID=10&testbedID=3&osID=4&raidconfigID=1&numDrives=1&devID_0=254&devID_1=213&devID_2=218&devCnt=3) with the exception of the top 2 Ultra320 SCSI drives, it even kicks the Seagate Cheetah 15.3 Ultra320 series.
Here's their full review (http://www.storagereview.com/articles/200401/20040126WD740GD_1.html) of the Raptors.

Re:You could go for a 74Gig Raptor it is a little above $200 I got mine for $214 they are really quite fast. If you check out storagereview.com you will see that they can compete quite well vs the 3rd gen 15K SCSI drives in single user environments even beat them some of the time, and may do quite a bit better in multi user once SATA controlers support TCQ. My drive is pretty quite too, no annoying noises at idle I'd say silent actually but yes you can hear it on read and writes which I actually do like. The drive is pretty cool running compared to my older Maxtor drive. It runs about 25 C and is cool to the touch.
I think you would like this drive I do.
