Multiple start-up disks in Lion

Hi,
I want to try out my new SSD with Lion before I completely ditch my old HD (lots of work-dependent stuff I can't chance loosing till I've fully tested on the new drive). I noticed in Lion you get multiple options at start-up if you hold down the option key (assuming you have boot camp).
My question is this: if I just drop my new SSD (preloaded with Lion) into the opti-bay via a converter, and leave my old HD in place, will I see both drives available when I hold option down at startup? In other words, if I have two Lion-loaded drives connected internally, can I just choose which drive I want to boot into using the option command, like with a boot camp or recovery partition?
Thanks!

 

Great; thanks!
I was unsure since I know you can only have one boot camp partition but when I saw the third option for the Lion recovery disk, it made me wonder if this would be possible. (I only asked first instead of just trying it because I didn't know if running two HD's with Lion installed could cause any system instability.)
