| Can you have an ssd for main hdd, and... Another SSD set up to provide ssd caching for a secondary hard drive? This is a z68 board... |

Don't see why not.

if you have a main drive where your os is installed running a ssd, there really will be no gain with using a 2nd drive to run the caching off of it. |

| Reread. The ssd caching is for a secondary hdd, which is a 3tb spinning hdd. My main sdd is a 128 gb mush kin... |

You probably know this already but:
»en.wikipedia.org/wiki/Smart_Resp···chnology
Basically states that the max size is 64GB for any SSD drive and your board is designed to do exactly what you want to do.
The only issue I could see, from what I've read of the spec is you'd have to make sure your 64GB SSD was caching the spinning drive and not your other SSD, I'm assuming the BIOS would have this function.

I'm watching District 9 again, and I've come to realize something: Wikus's got it all wrong. If I were morphing into a 9 foot tall hyper-dextrous alien that can shoot lightning bolts and get high off cat food why would I ever want to become human again? |

You absolutely can do this. I just set up something very similar with my newest build / upgrade.
I went with a z68 and upgraded to a new SSD. I used my old (60gb) SSD as a cache for my raid 5. Stuff is blazing fast.
Enjoy. |

| I'm guessing it disables trim and I must rely on garbage collection though, right? |
|
| Do you mean on the cache SSD? I am not sure if it disabled trim or not, to be honest I did not check. I will try and check tomorrow for you. |

That's not configured in the BIOS but rather in the Intel RAID driver interface.
Basically in order to achieve this you need to put your SATA controller in RAID mode in the BIOS (NOT AHCI or IDE), install all three drives (make sure the 3TB HDD and the cache SSD are both connected to the Intel SATA controller), then you install Windows 7 on the bigger SSD, install the most recent Intel RAID driver/software, reboot, start the Intel RAID software and there'll be an option in there that says "Accelerate". Enable that, a wizard will pop up asking you which drive to use as a cache (select your cache SSD), how much space to use for cache (up to 64GB) and which drive to cache (select your 3TB HDD).
It'll also ask you if you want enhanced or maximized mode. Enhanced mode is just a read cache while maximized is both read and write cache. Keep in mind if one of your drives (or the driver) fails in maximized mode you may end up losing data that's not been written to the 3TB HDD yet. There's minimal performance difference between enhanced and maximized more, unless you use write-intensive apps a lot.
Save, reboot, enjoy.

Yes, TRIM is disabled on the cache SDD because it goes through the Intel RAID driver. Apparently the driver has it's own version of TRIM which enhances the garbage collection in that mode though. |

That is how I set up my machine. I have an OCZ Vertex 2 60 gig as primary and a standard HDD for my secondary. Just make sure to run SSD Tweak to get the best out of it. |

How's the speed improvement?

| It basically gives your main hdd about 80% read speed of your ssd. It is a good improvement for the larger hard drive, but I hate the garbage collection instead of real trim... |
