I recently put an LSI 9260-8i and 4 WD Red's into my server, which runs ESXi 5.5. I am running MSM 14.11.01.00 in a Windows 2012 VM with Java v8u40 (Also tried with v7u76). All drivers are updated under ESXi. In the LSI BIOS, all drives report 6gbps connections. Under MSM, one drive was showing 3gbps negotiated link speed. I made note of which drive it was, restarted, looked in the BIOS and all showed 6gbps. I changed SAS connectors, rebooted, checked in the BIOS and verified all was at 6gbps, and then I launched the host and checked in MSM and a different drive (by serial number) shows 3gbps, so the problem doesn't simply follow a drive. I also have used 3 different SAS cables at this point. I am kind of thinking its an MSM problem because the BIOS shows all is OK, but I am not positive. Any input would be awesome.

I don't think there's much point in worrying about this, as these drives top out at around 150MB/sec so it shouldn't affect anything.

It's not a problem with the port you have them connected to right? I would check something that can view SMART error logs (if you can see it through the controller or it has that capability) to see if the "UDMA CRC Error Count" is non-zero, maybe something is causing link CRC errors that are downgrading the speed.
