    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?
