One question, I have a third drive that is a 2TB Seagate, will having a WD and Seagate drive have any conflicts between each other?
No problems at all.

If you have a 2TB drive, why not make backup images of your SSD onto the 2TB drive and skip the 160? The images are just a file, and they are about 1/4 to 1/2 the actual installed size of your OS. So, if you have 40GB on the hard drive used, your backup image might be 19-25GB.
