Seagate Momentus XT hybrid hard drives

Seagate's new hard drives combine 4GB SSD's with standard platter based hard drives.  The result and benefit of this is, much lower cost, with similar performance to a standard SSD.  I was skeptical at first, but check out the video below and you will see why i am ordering some of these.  If you want to buy them they are available at amazon for $99.99(250GB), $125.99(320GB), and $134.99(500GB).  Amazon
