Look at the ADAPTEC RAID CONTROLLERS and company.
I'm in the market for building a new rig to my worn out Q6600 + GTX 260 system. I will probably go with pretty standard modern equivalents like i7 2600k and a nvidia 400 or 500 series (you should toss in your 2 cents on this).
My real question stems from my desire to have seriously upgraded storage. I want Raid 0, I know that for sure. What do you all think about SSDcaching? I don't want to go solely the SSD route, because I feel like the technology is still pretty immature. Is a RAID 0 setup system possible with SSD caching? What about a RAID 0 setup with 2 cache SSDs in RAID 0? I think the latter would be pretty bad ***.
