How much faster is 10,000 vs 7,200 RPM

[Day03]

I've always had 7,200RPM hard drives so I cannot compare it to 10,000RPM raptor ones but I'm wondering if there is a big difference in doing everyday tasks? Is it worth spending more on such drives?

Thanks for the link, that clears up a few things.

I would like to hear from anyone who had a chance to compare both.
