    Usb 3.0

    Hi,

    I'm looking to buy a 320Gb portable, usb-powered, external HDD that has USB3.0 functionality, for use as a bootable Ubuntu drive which I can connect to any PC and boot into.

    Would I be best to install Ubuntu onto this drive using a USB3.0 capable machine?
    If so, what would happen if I booted into a PC using USB2.0?
    Or, would I be better just installing Ubuntu using a USB2.0 machine?
    Or doesn't it matter which machine (USB2 or 3) I install from?

    Cheers,
    Baldrick

    Re: USB3.0 question...

    Hello,

    since there is a possibility to create a bootable usb stick, I do not think that usb 2.0 or 3.0 will make so much of a difference as long as you are not intending to use this disk for other purposes, which will require transport of a lot amount of data. Other users might provide hands on suggestions to you.

    Happy ubuntu-ing,
    Regards!

    It doesn't make any difference whether you use a USB2 or USB3 connection to install and to run the OS from.

    Except for the speed difference your system will behave identically no matter which connection you use.

    To get USB 3 data transfer rates to and from this external USB hard drive it will need to be plugged into a USB 3 capable USB port. If the machine only has USB 2 ports then the transfer rate will be at USB 2 speeds.

    It is a machine. It is more stupid than we are. It will not stop us from doing stupid things.
