What do you mean by "share"??
No reason why two different ssd devices can not be installed together, much like multiple hard drives.
If you mean can they be combined into a single 200gb address space, then yea, that is possible.
One way might be to use raid-0.
That has reliability implications.
The other which I am not completely certain how to do is to set up a JBOD or single group of devices.
You do that in windows.
