But don't expect your off the shelf WD SATA piece of crap home hard drive to hit that speed. There's a lot more factors related to hard drive speed than RPM. That's just one small factor. A higher density 5900 RPM drive might perform 3 to 4 times faster than another lower density 7200 RPM drive.
RPM's aren't everything any more than GHz are for CPU ratings.

1TB Western Digital Caviar Blue hard drive is what i have how much do you think????
Run a HD Tune read benchmark against the drive. The curve should be smooth and monotonically decreasing. The outermost tracks should have a sustained transfer rate of about twice that of the innermost tracks. The actual transfer rate will depend on the RPM and number of bits per track (data density).
You can determine the number of heads, and therefore the data density, by running a shortstroked HD Tune benchmark.
