We measure the system USB 3.0 performance by using the excellent Patriot SuperSonic Magnum 256GB USB 3.0 drive, which we reviewed back in February this year.
Performance via the USB 3.0 ports is excellent, scoring 277 MB/s read and 164 MB/s write, in the sequential tests. Due to the nature of this kind of flash, and via the USB 3.0 interface, 4k and 4k QD32 performance is substantially worse than from a native SSD drive across a SATA connector.
