No raid ssd max speed is around 550 MB on sata3 port from the 768 that the port will allow.
No raid ssd max speed is around 300 MB on sata2 port, you limit your ssd because of the max port of 300 MB.
Ssd normal speed is around 500-550 MB
Sata 3 port or 6GB port is max 768MB
so i dont know if in raid 0 they will join and be 1536 MB because the ports dont let u go higher than 768, but maybe im wrong.
Sata 2 port or 3GB port is max 300MB i dont know how u get 800mb, u should get max 600mb not even, i think in sata 2 port max ive seen is 540-550 mb
It is adviced for max performance to use on sata3 6GB the Ssd or the raid of ssd and on sata2 3gb use for hdds or raid of hdds, hdd even if is sata 6gb will not go more than 200mb
and all to be the intel ports.
Also check this, a good ideea is use RAM for cache RamDisk:

Put your different OS's one on each. It will be just as fast but be 2 separate drives. I don't think the rest of the hardware can realistically handle anything faster so you won't see very much gain in Raid0. If you are using HDD's in the loop they will be your bottleneck when you transfer files from drive to drive. That is why you cache them with RAM. If you transfer files from SSD to SSD with no cache then you will notice a much greater gain being able to read from one and write to the other @ 500MB/s. It will greatly improve your drive to drive speeds.
