aren't the 10k drives the ones. that had the outer edges of the 3.5 inch platters breaking the sound barrier?

Well, a 3.5" platter has a circumference of 9.6211275 inches. (pi * r^2)
At 10k RPM, that's 96,211.275" per minute, or 8,017 feet per minute, or 1.51 miles per minute, or 91 miles per hour.
Speed of sound is 761mph.
So it would take a (761 / 91 * 10k = ) 83k RPM drive.

I came up with 73.5k rpm to break 761 mph. Isn't pi*r^2 area? I used pi*2r.

pi*2r = pi*d is circumference. pi*(r^2) is area.

Ah. Okay. Urban legend I guess. Of the nerdy variety.

Oh yeah.
Weird, I have them switched it my head apparently, cuz I did the other one the other day when I needed area.

Coming to you live, from the new PC:
Returned the 10k drive and went with the 1TB Caviar Black. Took a performance hit, but saved a bunch of money and gained a ton of extra storage. Felt that was more important than the system booting (once a day) faster or game levels loading a bit faster.
ASUS P6T motherboard. Holy shit. Options upon options upon options in the BIOS. NONE of it explained very well. Overclocking options seem limitless with the board. WAY advanced user type stuff. Crazyness abounds. BIOS is VERY intimidating. But, with everything set to auto, the PC is obviously working. However, my 1600 memory is only running at 1300 or something like that. So, I'll be messing with that after more reading. I knew going into it that to use the 1600 memory (or 2000) that I'd have to overclock something.
CPU installation. Wow. That's changed. The pins are now in the motherboard and the CPU has flat surfaces that those pins come in conatact with. When I was locking the CPU into place, it didn't seem like it was seated properly. The 'cage' didn't want to come down on it. After about 50 reseats, I just forced it down and hoped for the best. The locking arm is actually bending under the stress. CPU fan was the easiest install EVER. Seriously. NO forcing. No threat of a slip and stabbing of the motherboard. You'd have to be as retarded as those infomercial people that can't open a jar without spraying the contents of said jar all over yourself and your house without the aid of the new device they are trying to sell to you, to screw up the cooling fan install and damage your board. No forcing. No pushing. Nothing. Just put it in place. Turn the locks 1/4 turn, and walk away. VERY good improvement.
Memory install. Same as it ever was.
Video card install. Those are getting HUGE, and the MB makers know it. So, all your drive plugs are either out of the way, or they face back towards the back of the computer so your cords fit under the cards. Smart. Thank you. So, the cards went in fine.
OS Load. Well, I'm running XP still, so, I had some issues there. Long story short, I have to tell the BIOS to use my hard drive as an IDE drive, which slows it down, cause the XP install disk doesn't have SATA drivers on it. Vista does, so no issues for you guys. My options were to create a new XP install disk with the drivers 'slipstreamed' onto it, or use a floppy (which I don't have any more) to load the drivers during install. In the end, I have to do some clunky stuff to switch my drive into SATA mode after install. New driver loaded, maybe some registry changes, etc. Haven't crossed that bridge yet.
I'm still loading stuff, so, can't speak of the fasterness of it all. When I get some games loaded, I'll let you know. Unfortunately, I'm playing UO again more than anything else. That's not a good game to judge this system. TF2 is downloading, as is episode one of HL. Better choice there. I've got some time left on Warhammer Online as well. That pushed my last system beyond what it could do. So, that will be the best test so far.
I'll keep you posted. So far, it's loading and running, so that's good.

Played a little bit of HL2:E1 and it looked gooooooood. I put all the settings to the highest possible with some other stuff that I didn't know what it was as high as it could go (assuming the higher numbers = better). It ran suuuuuper smooth and the levels loaded super fast (compared to my old system which loaded super slow). The picture was amazing with absolutely NO jaged edges on anything. As soon as it loaded and started playing, I could tell a HUGE difference from how I use to play HL2. Incrediblely smooth action with super clean lines. Awesomeness abounds.

You are suggesting I buy an EA game? As if. . . .
