Testing:

For the testing portion of the review we will compare results from CrystalDiskMark 3.0.1 and from real world file transfers. The Xporter XT Boost drive will only be run in USB 2.0 mode (since that is all it supports), while the Supersonic drive will be run in both USB 2.0 and USB 3.0 modes.

CrystalDiskMark 3.0.1:

First we will take a look at the USB 2.0 results for both drives so we can see if there was any performance gain using the Supersonic on the 'old school' technology.

The screenshot below shows this benchmark's results for the Xporter XT Boost drive. The read speeds are very good for a USB 2.0 drive, but you can see the abysmal write speeds...


Xporter XT Boost - USB 2.0

As you can see in the image below, the read and write speeds for the Supersonic drive are very good for USB 2.0. The read speeds are very close to the Xporter XT Boost drive, but the write speeds are much better on the Supersonic.


Supersonic - USB 2.0

Finally, CrystalDiskMark was run on the Supersonic drive using a USB 3.0 port on the test system. From the image below we can see that the read results do not disappoint, while the write results are a bit below par.


Supersonic - USB 3.0

The write speed was about 6 MB/s higher than the advertised maximum while the read speed was 11 MB/s lower than the advertised maximum.
