I finished building my SAN using Windows Storage Server 2012 R2. Besides the two drives for the OS, the storage has 12 Hitachi enterprise class SATA III drives and 4 Crucial M500 SSDs, (they were relatively cheap for 480 GB).
I created tiered storage using all the hard drives with a two-way mirror. I did some benchmarking before installing PrimoCache and then after installing PrimoCache. Below are the results.

After Primo.

What is really nice is the 4K performance increase. I tested with another app and it showed 75,000 IOPS.
