Why don't S/ATA drives ever operate above 10,000 RPMs?

Just curious. I think Western Digital is the only company that makes a 10,000 RPM SATA drive, everyone else is limited to 7,200 RPM.
Meanwhile, SCSI and Fibre go up to 22,000 RPMs.

Market conditions.
15000+ RPM drives are expensive. People blowing that much on drives are using SCSI/FC anyway.

I would also guess that it is because of heat issues and case issues.

Didn't SCSI go up to 10K RPM back in the mid-nineties?
I vaguely remember these being quite widespread on old PowerMacs (or maybe I was just dreaming again).

I just checked, and it seems that Seagate released the first 7200 RPM drive in 1992, the first 10,000 RPM drive in 1996, and the first 15,000 RPM drive in 2000. Seagate sold the first 7200 RPM ATA drive in 1997. (All scoured from wikipedia articles.)

SCSI was widely used until the Beige G3s, which did have a SCSI bus but the hard drives were all ATA still. The SCSI drives were only 2GB or so.
The B&W G3s didn't have a SCSI bus but many came with SCSI PCI cards.

Yeah. I have an Apple 10k RPM drive.

You'd think there'd at least be a niche market for 15K RPM SATA drives, especially for multimedia and games.

I thought so. That's why when I went shopping for a 10K RPM Raptor for my MacPro I was thinking: "Haven't we gotten further than this in the last ten years?"

Ugh, I had an 8 gig 5.25" drive once. That thing was so freaking loud! But it lasted a long time, so I guess I can't complain much.

It's marchitecture to distinguish SATA drives from SCSI drives. That's particularly `strange' considering SAS is based on SATA.
BTW, I haven't heard of any 22k drives on the market …

I don't suffer from insanity, I enjoy every minute of it.

I've got a 3 GB Bigfoot that's still in active duty.

I tried to do a search for one and I can't find them anymore. I did find articles about 22k RPM drives being too loud and too power hungry. Maybe they stopped making them, but I know they existed because a buddy of mine had a few.
