I purchased LSI 9211-8i on ebay a while back. I'm using this cable to attach three 3TB SAS drives and one of the cables that came with the card to attach three 3TB SATA drives I picked up from Amazon. SAS drives are showing as 6.0Gbps but SATA remain at 3.0Gbps. Any thoughts before I return them? I've verified speed in the OS and the Avago BIOS for the card.
