Benchmarking
For this review, we’ll be comparing results from the drive in a USB 3.0 port to results from the drive in a USB 2.0 port. This will not only show us the drive’s performance in each situation, but also highlight the difference that USB 3.0’s extra bandwidth can make.

Already we can see the difference that USB 3.0 makes in the Physical Read test, which measures a storage device’s raw potential. While the USB 2.0 test capped out around 33MB/sec, the USB 3.0 test has the Supersonic clocking in at 122.35MB/sec—a full 25% faster than claimed! As expected from solid-state memory, this performance held steady over the whole drive capacity.

In the File Systems test, the scores are somewhat reduced, but the pattern holds consistent. The USB 2.0 test was once again capped by the bus, this time around 30MB/sec. The USB 3.0 test gave us a diminished but still impressive 103MB/sec. Curiously, the access time rose a bit from the USB 2.0 test score of 0.56ms to the USB 3.0 test score of 1.21ms. In practice, both of these times are well within acceptable bounds—and, it’s worth noting, somewhat better than the access time on the Intel SSD results.

The Removable Storage test gives us measurements based not in MB/sec, but in IOPS. This gives us an idea of how the drive performs under a heavy load, i.e. multiple file transfers at the same time. IOPS performance is typically highest when dealing with cluster-sized files; in this case 4k.Here the Supersonic shows a marked difference between USB 2.0 and USB 3.0, though it is not clearly dominant over magnetic media as it was in the sequential read tests.
