    Until there is sufficient mass and variety of USB3 products, eSATA and FW800 will be the better products.

    eSATA in particular will likely dominate External HDD in the long run, because it is simpler and (much) cheaper.

    Sure there a lot of excitement over USB3, but history tells us that does not mean it will be a hit.

    And as it is, Intel may drop USB3 and go with its even faster and cheaper "Light Peak", if you believe rumors from Intel.


    It is much to early to see what will happen. Mid 2010 may be good time to really know.

    One thing USB3 has going for it that eSata and FW### do not is plug compatibility. There's no physical difference between USB3 ports and USB2 ports, something that's not the case for the other two. Backwards compatibility in the peripheral world is very important.

    Exactly. This is why USB3 will be an instant hit.

    Later on, LightPeak may catch up. In technological terms, LightPeak is far superior. However, the superior product does not always win. Think of Betamax vs. VHS. (I don't remember it, too young) I have been told that Betamax was superior but VHS won. Later on, the superior technology did win (Blu-Ray), but this isn't always the case.

    I seriously hope LightPeak takes over, but I wouldn't bet on it.

    You are incorrect sir.

    ALL the USB3 connectors are different.

    There is visible physical difference with USB3 B and USB3 mini connectors.

    USB3 A will fit in USB2 A, but it has added wiring.

    IOW, USB3 is back compatible to USB2, just like FW800 is back compatible to FW400.

    This posting will explain:

    Edit:
    Yes, you can plug USB2 cables between USB3 hosts and devices, but they will only connect at USB2 speeds (unless they use Fiber Optic, in that case it will not work).

    So? If you connect a FW400 device to a FW800 device not only do you need a physically different cable (100% of the time), it also will only connect at FW400 speed. At least with USB you don't need to buy a different cable unless it's for a FO connector.

    Edit: I'd also posit that for a great many USB# devices connection speed doesn't even matter that much. How much bandwidth do you need to send a word document to a printer? Contrast that with the need for speed with FW devices and the difference between FW400/FW800 becomes much more of a problem than the difference between USB2/USB3.

    In other words, "lrn2grammar." :D

    And yes I agree, I want to see FW3200 ports on Macs. Soon!
