Z68 SSD Caching with Corsair's F40 SandForce SSD

I have to admit that Intel's Z68 launch was somewhat anti-climactic for me. It was the chipset we all wanted when Sandy Bridge first arrived, but now four months after Sandy Bridge showed up there isn't all that much to be excited about - save for one feature of course: Smart Response Technology (aka SSD caching). The premise is borrowed from how SSDs are sometimes used in the enterprise space: put a small, fast SSD in front of a large array of storage and use it to cache both reads and writes. This is ultimately how the memory hierarchy works - hide the latency of larger, cheaper storage by caching frequently used data in much faster, but more expensive storage.

I believe there's a real future with SSD caching, however the technology needs to go mainstream. It needs to be available on all chipsets, something we won't see until next year with Ivy Bridge. Even then, there's another hurdle: the price of the SSD cache.

For $110 today you can either get a 20GB Larson Creek drive from Intel, or a 40GB SF-1200 based SSD from Corsair. Given how well SandForce's SSDs perform on their own, I wondered how one would stack up as a SSD cache. Read on to find out!
