I wonder if there is a way to check if an external USB 3 HD drive support and actually use UASP transfer.
 
Ever looked at System Information > Hardware or SAS?

OS X 10.8 Mountain Lion does support UAS and uses a different kext when such drive is connected.
 
Off course I've checked system Info.
IOUSBAttachedSCSI.kext is loaded (IOUSBMassStorageClass.kext is not) does this mean that UASP is working?
 
Thanks, just what I needed.
So I'm running uasp after all :)
