    Folks,
    I am thinking of installing my system on a 64Gb external USB key 3.0 and I wonder if this will make my Mac run faster (My system is currently installed on the internal HDD [1Tb, 5400 rpm] of my MacMini)

    Do someone have any experience on this?

    Thanks in advance for your help, :)
    Arnaud

    I keep a cloned backup on a USB3 key, for emergency restore purposes only.
    I serves its purpose as such but it is way-way too slow for regular use.

    Not a good idea, and it sure won't be faster (not after a while, no TRIM and garbage collection on such a device); using a SSD in a USB 3 external case however would give you the speed and sturdiness you're looking for.
