    As above. Intend to get an external HDD enclosure that has USB 3.0 and USAP supported (USAP more expensive). I'm using an iMac 2011 which doesn't come with USB 3.0. However some articles stated that USAP will work for USB 2.0 as well. Is that so? If not probably I'll save the cash and get the normal ones instead. Thanks!

    I think you mean UASP? USB 3 is backwards compatible period. Whether the enclosure supports UASP, or not, does not break the backwards compatibility.

    In a nutshell, yes, it will work.

    It definitely speeds up USB 3 transfer speeds. I am not sure if it speeds up USB 2 speeds, because I have never tested this and I have no Macs with USB 2 to try it out with my UASP enclosures.

    Thanks for your advice. I guess I'll just go ahead with it, shouldn't do any harm I hope (unless compatibility issue). Maybe in future if upgrade to newer iMac at least this still can work.:)
