That is silly. Just make a big raid0 of it. If for some reason one of the 3ware cards takes a dump you WILL LOSE ALL YOUR DATA. I have seen this mistake (if it is) before at www.tweakers.net where they configured the 4 disk into a raid 01 instead of 10. If you want redundancy make a raid0 on the 3ware disk and a raid1 of these 2 3ware cards.
That is make 2 raid1 devices and then a raid0. If something happens to either one of the raid1 array logical devices (not disk but software failure) everything will be lost. Which was exactly what happend. They raid controller (Ami megaraid) got upset after one disk died and they lost there complete Mysql Database.

Which is exactly the reason to avoid the above mentioned configuration. If one card dies you have just lost all your data.
