I had that. An SSD and a couple of normal hard drives. The SSD had Vista on it so I installed Win 7 Beta on one of the hard drives. So, are you thinking of a dual boot?
I have my OS on my SSD and the rest of my "stuff" on my HDD. I can boot from my SSD with no problem but how can use the "stuff" on my HDD as if it were my primary drive?
