All else being equal, a RAID1 will be more reliable than a single drive, whether it's magnetic or SSD.

Also, what form factor / interface is best for the SSD OS boot device on a server M/B? Anything I should be looking for?

If you're going for a RAID, you may as well also go for hot-swap drive bays, so that you can change a failed drive without downing the system. At that point you may as well ask your vendor what they suggest. The SSDs I have in a RAID1 configuration are 2.5" drives.
