10,000 RPM vs 7,200 RPM?

Specs: Vista Ultimate, 3.00 HT
I'm looking to buy a new HDD, but I have know idea what to look for. This HDD will be used for gaming, so I suppose I need a fast one. I see these HDD's that spin at 10,000 RPM with a transfer rate of 3000 Mb/sec and 7,200 RPM with the same transfer rate. My question is which HDD is better? They both have the same transfer rate, but one spins faster than the other, so what's the big deal about the 10,000 RPM HDD? Shouldn't it have a higher transfer rate? I'm so confused. If this can be explained I would appreciate it so much! Thanks for reading!!!

3000 Mb/sec is the theoretical speed that the SATA port can do, not the speed that the hard drive can actually achieve. 10,000RPM drives will have faster access times and transfer rates but I cant stand the noise, and they are massively noisy. Think of the old Quantum Fireball drives, very loud and ear grinding.

Generally 7,200RPM drives are adequate for 95% of people and still provide good speeds.

The newer Raptors are much quieter than the old ones. I bought one, but to be honest I'm not sure its worth the money (they are much more expensive). I think any performance increase under real world conditions is barely noticeable for most people, even if the benchmarks are better.

Plenty of RAM is your best bet, but like all things it depends on your priorities and your budget.

The average seek time (latency) is faster on the 10,000RPM drives. Is that worth the extra cost, noise and heat? Not IMHO.

Can you use SATA or do you need IDE ATA? Post your computer model or other specs for better advice. There are other considerations.
