Mixing SATA3 and SAS3 drives on same HBA.

I built my server on a Lenovo ST250. It has SAS 12Gbps backplane and cables. I dropped in a SAS 9300-8i HBA, but have been using it with 6TB shucked drives. Recently decided to add in two 12Gbps 1TB SAS SSD as cache pool. The SATA spinning drives and SAS SSD all run off the 9300-8i. Anyone knows if the HBA is smart enough to run my array with SATA3 but run the cache pool with SAS3? Will my cache pool run at 12Gbps? Any ways to actually benchmark the cache pool to verify its running at 12Gbps?

    It's not a problem mixing SAS and SATA, as for the link speed you can check it by clicking on the device on the main page.
