A few weeks ago Crucial released a new product that:

• Combines a cost-effective, high-performance SSD with an existing hard drive to enable the best of both worlds: SSD-like performance with the high storage capacity of a hard drive.
• Comprises a 50GB Crucial® m4 SSD, a 3.5" adapter bracket, and caching software.
• Simple, two-step installation includes connecting the SSD to the motherboard with a standard SATA cable followed by installation of the software.

Cost is $117.99.

I'm wondering if any of you have heard of this product and what your thinking would be as a means to inexpensively speed up your system.

Thanks.

I thought long and hard about a similar product when SSD's were much more expensive. 

These cache products probably make sense if you have terabytes of data on hard drives and work on a few gigabytes at a time: something visual like movie editing or CAD.  Even so, you are probably better off with Intel's Z68 and SSD 311 solution than a kluge plugged into a random SATA port.

I finally came to the conclusion that, if I was going to the trouble of opening my computer case, attaching a drive to the motherboard, mounting the drive in the case and installing software...well  I might as well spend a few dollars more and port the entire operating system and all of my programs to a larger SSD.  That is what I did and have never looked back.

Thanks for a sensible response.  I do like to mess around with new stuff though
