    I just bought a Lacie Minimus USB 3.0 external hard drive today. But for a reason, it doesn't have the speed of USB 3.0. I actually suspect it to be a USB 2.0 disk, even though the box says it's USB 3.0-compatible.

    When I check out System info > USB > Maximus USB 3, it says the max speed is 480 Mb/sek. But that's the max speed of USB 2.0, not USB 3.0!

    And for the record, the first thing I did was to format the disk. I didn't use the setup application, but have installed all the applications available from the model's software support site later. Still, the speed is not noteworthy faster than USB 2.0 – and yes, I have the lastest MacBook Air mid 2012, so it supports USB 3.0.

    So I really wonder what the problem is. Is it a USB 2.0 disk wrapped in a USB 3.0 box, or is the problem that I ignored the setup application and deleted (formated) the disk before I even registrered the product?

    Just because it says USB 3 support. Does not mean it is USB3. It's very misleading. You will also find the HD is not even capable of 480mb/s, most likely it's a 5400RPM, so you'll be lucky to see 80-100mb/s. the only way you are going to see faster speeds is to get a SSD drive connected to a USB3 or thunderbolt port. Then you will see 300-400mb/s write speeds

    Thanks for the reply! It sounds logical what you just said. But my question is then: Are they allowed to advertise that the disk is four times faster than USB 2.0?
