This test shows you why USB drives are designed to copy and store files, and are not suitable to run an operating system (even though this is certainly possible). The new Kingston DataTraveler Ultimate 3.0 G3 is really bad at small random reads - it was the worst drive in this comparison, irrespective of whether it was used with a USB 3.0 port, or a USB 2.0 port.

When it came to large 512 KB random reads and writes, the Kingston DataTraveler Ultimate 3.0 G3 exhibited the same characteristics. It was very fast at random reads but much slower at random writes. When used in the USB 3.0 mode, it was actually almost twice as fast as the next fastest flash drive - the DataTraveler Ultimate 3.0 Gen. 2.
