Just like the title asks.

Can my motherboard (Asus Rampage IV Gene) support an SSD in AHCI and a pair of HDDs in RAID0? Below are the drives I'll be using if that makes any difference.

SSD: 1x Samsung 840 EVO 750 GB
HDD: 2x Seagate Constellation ES.3 ST4000NM0033 4TB

I'd really appreciate help from those of you who have experience with running a single SDD and a 2 HDD RAID0 configuration on a single system. The only thing I've found on this was from a similar thread on Tom's but for a different motherboard (click for link). Perhaps it's possible to adapt a solution like the one selected in that thread but for my motherboard?

I like that AHCI allows my SSD to control itself internally while retaining trim.

I also need RAID0 for increased fault tolerance.

Can I make both work together? What about if I use the x79's native SATA 6.0 Gbps controller plugs for the SDD and ASUS's 3 Gbps controller plugs for the HDDs? I'd imagine the motherboard's SATA setting would be RAID either way, but maybe it's possible to configure this with AHCI enabled.

Also, I am not 100% set on any particular mode for my SSD (e.g. AHCI). I just want to retain it's very good internal controls and be sure that trim will continue to work, if at all possible, while running my RAID0.

Specific information on this has been hard to find, so please chime in if you've set up something like this before.

Thanks!

I'm fairly sure that RAID mode has all the features of AHCI.

Would that remain the case by default operation, or would I have to setup anything in particular? I've never built this particular setup before.

I'm pretty sure it would be by default, but I'm not certain.
