Why don’t any specs say what speed the Caviar Green drives are? Are My Books for Macs running at 7200 rpm?

Hi there

Caviar green drives are SATA 6 Gb/s and run at 5400 rpm.  About your my book for Mac I believe they have a green drive inside but im not 100% sure about that.

I found tech specs on line–the Caviar green are running at 7200 rpm.
