Is the processor in the x220 a Sandy Bridge

[fjs08]

Been waiting for Ivy Bridge, but just read an article on PC World that mentions looking at Sandy Bridge computers.
Prices should be good and there isn't "that much" difference between Sandy and Ivy Bridge processors for the basic computer user, ie ME.
How do I know which models are Sandy Bridge??
Is the X220 a Sandy Bridge notebook.
Looking for something very portable, light, lots of ram, fast, ThinkPad quality, w an SSD I guess it is called HD.
Thoughts and recommendations.
Thx.

All X220 have a Sandy Bridge CPU. If I were getting a X220, I'd get it with the standard hard drive, then put in a mSATA SSD. A mSATA is a small SSD that plugs into the miniPCI slot on the motherboard. It's located under the palm rest on the X220. The benefit of this set up is you can use the mSATA SSD as a boot partition for speed and keep the platter drive in the main bay for storage where speed is not as important. Of course if you need WWAN, the mSATA SSD is a no-go as they share the same port.
