HS takes a look an in-depth look at Intel's Smart Response Technology, one of the most significant new features of the Intel Z68 chipset. Includes benchmarks. Check it out over here.
Here is a snippet:
"Intel Smart Response Technology (SRT) is designed to bridge the middle ground between traditional mechanical hard drives and solid state drives by combining the two. Although high capacity SSDs are quite expensive, low capacity units are much less expensive and achieve similar levels of performance. Intel's SRT lets you use a low capacity SSD to boost the performance of a mechanical drive by using the SSD as a cache."
