  1. I've wanted to make a bootable OS on an USB instead of an SSD, but then I came across a few forum topics somewhere saying that It's slow, even slower than HDD.
    Can someone confirm, which is the fastest and which the slowest?

    If you have USB 3.0 and a fast thumb drive like Sandisk Extreme, Corsair Flash Voyager GT Speed, or Kingston Data Traveler HyperX, it will be faster than a HDD, about like a first generation SSD. USB 2.0 is going to be slower than the HDD, so in this case, an external HDD would be just as fast as and cheaper than a large 2.0 thumb drive

    What kind of transfer speeds can I expect from such a USB 3.0 drive?

    Slower than a modern SSD and faster than a regular HDD.

    Hmm I figured that, but how much slower.. 2,3 times?

    Well it really matters on your motherboards USB3 controller. USB3 is usually 5GB/s. That is 1GB/s less than SATA.
