SSD RAID is next to useless, unless you're either putting your OS on RAID 1 and you're extra worried about your drive dying and don't want to go through reinstalling, or you run a webserver or some other important data that benefits from being on an SSD, and can't be lost.
RAID0 was great with traditional HDDs, because it reduced the bottleneck caused by hard drives. SSDs are really good where hard drives aren't, that is, random reads/writes and access time (think OS drive). They're also better at sequential reads/writes, but they're so good because they stay strong where hard drives would crumble. RAID0 helped hard drives in this area with two hard drives working on the same task instead of just one, thereby improving those pitiful random reads and access times, but SSDs still win over RAID0 HDDs by a large margin here.
In your situation though, RAID0 would simply be more convenient to have one large drive rather than two smaller drives with which to split up your OS, programs and games? over... but it will become a lot less convenient should something bad happen to one of the drives, all your data goes away then.
