I am working on setting up a Bacula backup to an external hard drive. The server I am running this on has an on-board USB 2 controller, however the external USB 3 SATA drive doc I am using is only being recognized as USB 1. It does correctly load as USB 2 or USB 3 if I move it to my windows machine which has both USB 2 and USB 3 ports.
Before I spend money adding a USB 3 card to the server in order to get the external drive doc to load as USB 3, I was wondering if anyone had any good or bad things to say about FreeBSD's USB 3 support.
Would I be a lot safer spending money on an eSATA card and a eSATA doc, knowing that this would give be better performance, but would prefer to not spend any more money than I have to.
Or maybe someone would have an idea as to something I could tweek to get more than 1MB/s transfer speed from my existing setup, if I could get the full speed of USB2.0 this would run adequate for my needs.

Current machine is running a Biostar TPower N750 Motherboard, and the external drive doc is an INEO I-NA317U-Plus.
