Macbook Pro USB 3.0 RAID ZERO with USB sticks

What happens when you try to stripe two USB 3.0 sticks together in a RAID 0 on a 2012 Macbook with USB 3.0 support?

I decided to find out to see if there is any tangible benefit gains.

Here, I have two Patriot Supersonic Xpress 32GB USB 3.0 sticks for my test. I used Disk Utility to make a stripe set and had the set formatted HFS+. I ran Black Magic Disk Speed Test to see the before and after differences.

Single USB stick benchmark.

Striped Zero RAID benchmark.

In short, you will get twice the speed in RAID 0. Pretty cool!
