I agree with others here, don't go with hybrid drives in a RAID setup. That's only asking for trouble.
Personally, I like LSI cards. We have the 4i variant of
this one in one of our servers at work and it's our best performing RAID card (in RAID-6, with 4 drives versus some of our 6-disk arrays with 3Ware/Adaptec cards.)
I always get at least WD Blacks for RAID. I would recommend WD RE series drives or Seagate Constellation ES drives if you're "getting serious" about SATA RAID.
Edit: Are you still using the rig on your account or is that old? What are you putting this into?
No, those specs are really old. I'm certainly not talking enterprise or corporate level drive redundancy here, just a simple RAID setup that isn't over the top in price and where I'm not losing performance based on my motherboard RAID config. I've confirmed that the SSHD's can be setup in RAID 0 and 1, however, 5,6 and 10 haven't really been tested (however, I've been running mine for a good 6-8 months without issue.)

Can I use SSHD with RAID?
Yes you can, with excellent results, use Raid 0 and Raid 1 configurations. An SSHD in RAID 0, as compared to a single drive configuration, delivers performances as much as 70% higher.
Standard drives in RAID configuration should not be used with SSHD drives as this will nullify the benefits of using a hybrid drive.
Because current drives are not designed for multi-drive vibrations, they have not been tested with RAID 5, 6, or 10, and are not recommended.
