A developer from the FC forum says "windows caching is file-level caching, ours is block-level caching. They are not same."

I'm with Halk in that I won't be slumming it w/HDDs on any of my workstations but for a server with 256gb of RAM and terabytes of storage it's simply too costly to go pure SSD. I'm currently evaluating hybrid controllers from LSI and Adaptec but it looks like FC may be a cheaper and more effective alternative. I will be doing some tests.
