Been running 3 64 gb SSDs in a Raid 0 for almost 2 years. Zero hiccups, faster speeds, its been great. Doubling the chances is like going from .25% to .50% due to it being a raid. Id go Raid 0 every time.
Go with the single drive. Two hard drives in RAID 0 is a noticeable speed boost, not so with SSDs as the extra speed will be much less apparent. Never put drives in a RAID 0 setup unless it's strictly for temporary storage, or you have a very strict backup strategy, because all of your data is lost if just one drive goes bad.
If you're determined to go RAID 0, I would use Intel drives and nothing else.
