Yo Nam-uk,
I like your British sense of humor! Some times I am just busting nuts as well
A German speaking system would be a pain in the neck, in deed.
But back to your serious question:
Creating a RAID hooked up to the JMicron isn't a good idea because the controller shuts down at about 122 MB/s, moreover it is bent on PCIex 1.1.0. So that wouldn't perform pretty well.
Tow RAIDs on ICHR10 should be much better; the throughput could be at last ~600 MB/s (depends on the SSDs you chose) nevertheless TRIM does not work in a RAID area.
