When are mainstream drives going from 7200 to 10,000 (or whatever
higher) rpm?

Higher RPMs means higher power. Something like the Raptor might be
"short stroked", meaning the platter is smaller than normal. I don't know
if I can come up with documentation from WD on that though.

"The WDC360 also uses a 3-inch platter, versus the 3.5-inch platter
diameter of most desktop drives."

Using a smaller platter would mean a lower capacity drive, and since
people "buy based on GB per dollar", they wouldn't sell. People would
buy the 7200RPM ones instead, because they'd have better GB per dollar.

I presume there might be issues with the recording technology versus
RPM as well. Maybe the latest tech wouldn't work so well at 10K or
15K RPM.

There is a market for the Raptor, to be sure, but it may not be
big enough to justify all the manufacturers competing head to head
in the same market space.

There are some 15K SCSI drives out there, but they aren't cheap, and
likely aren't quiet either. With those, you'd get the benefit of
slightly better seek times.

If shopping for drives, by their characteristics, this database is handy.

If money is no object, look at this report. These are flash based
drives. The seek time is measured at 0.065mS. (RAM based drives would
be faster, but even more expensive.) With the right kind of caching
write driver, read and write can be made to behave similarly.

Not sure what the platter size is, but the 150 GB Raptor has a
greater data density than the older 37 GB models. I haven't seen
faster benchmark results yet.

They need to build the latest technology into the higher RPMs since
speed is part of the equation.

At flash drive prices of $80 for 16 GB (almost half the size of my
last hard drive), and given the rapid improvement, flash-based hard
drives are IMO a distinct possibility for the not too distant future.
Maybe we'll see a RAM drive revival.

A 1tb can be had for $199 USB or SATA. A 750 gb UltraATA is $165 and a
500gb is $96. But don't blink your eyes or the price will change.
I got this from Pricewatch.
