Does a mac support UAS (USB Attached SCSI)? Does a mac with USB 3.0 support UAS (USB Attached SCSI)? If it does, how can we enable it in OS X and bootcamp? I need better speeds for my external RAID.
Apparently what you need is already in Lion see this blog OSX Mountain Lion 10.8 UAS UASP USB Attach SCSI drivers

Note I have nothing to do with the blog.  It was at the top of the list when I googled USB Attached SCSI OSX
