Just finished installing one of the OWC mini-SAS 6G host adapters along with a Transintl DX4. I have a couple Crucial M4's mounted in the DX4 connected via a Monoprice internal mini-SAS to SATA cable. Also have a Voyager drive dock connected to the external mini-SAS connector via a mini-SAS to eSATA breakout cable. This gives me up to 4 internal SATA III SSD connections and 4 eSATA connections. Getting about 225-240 MBs writes and 450-485 MBs reads on the M4's. I am booting from an OWC SATA II SSD mounted in a drive sled in one of the original internal bays. Since the SAS card is an 8 lane PCIe card, I am getting 6G speeds with both M4's in operation simultaneously. Great solution if you are not fixated on booting from a 6G drive. I am using the M4's to stream samples in Kontakt for orchestral work. Hadn't seen anyone on here report using the OWC SAS card, so I thought I would recommend it.
