yep, it works with legacy USB speeds using legacy cords.

@arielnmz: To achieve USB 3 speeds, the specs define the performance characteristics the wire needs to meet. I'm not familiar with whether UTP could meet the requirements, but the spec is here: intel.com/content/dam/doc/technical-specification/…

And note the reverse on power: I have a USB2 device that draws too much power, it originally had a two-headed cable that let it draw power from two ports at once. Now it's fed from a single USB3 port with no gripes about drawing too much.

@Bilo: If you plug it into a USB 3 port it should work (a USB 2 port limits the current output to 500mA). But that's a waste of a USB 3 port. You would be better off getting a USB 3 enclosure for the drive and taking advantage of 10x the speed.

@JosephRogers, you're right. The USB port will be a bottleneck as long as it's slower than the peak transfer rate. You don't need to saturate it; performance will be degraded if the peaks exceed the bandwidth. On a good hard drive, that can be several times the USB 2.0 limit. With a good drive, you can benefit from USB 3.0's 10X speed, but you won't realize 10x the transfer rate. That was poor wording in my comment.
