Reading the reviews at newegg I read this. Is this possible or even practical

Western Digital Caviar GP WD10EACS 1TB 5400 to 7200 RPM 16MB Cache SATA 3.0Gb/s Hard Drive - OEM

FrankDAtank Tech Level: high

Pros: this drive is actually 6431 rpm's it’s a misprint. But if you send 18.7 volts to it instead of the recommended 12v's you can get 13,398 rpms. a 91.7 percent performance gain

Um... you would fry the HD in a second. either the circuit or if it could somehow handle the voltage (which I highly doubt) you would easily fry the motor and spindles. want to try a simple experiment? hook up an 80mm fan up to 18.7V and watch the sucker burn!

That new hard drive has variable speed (read the Toms review). Nice way to fry a hard drive though. Look at a CPU overclock. You raise the voltage to get higher clocks. BUT 18.7/12=1.56x the base voltage. Would you OC a 1.25V Q6600 using 1.95V (1.25V*1.56)? Plus I don't know if it's even theoretically possible to "OC" a hard drive. Where would you propose to get 18.7V power? Oh and the platters would probably shatter or otherwise break. Thats why 10k and 15k drives use smaller platters and can't offer higher storage capacities.
