Super Speed USB 3.0 Performance Testing

There are a number of different Super Speed USB 3.0 host controllers out there. In order to know which ones perform the best we run a series of tests that will put the controller through the ringer and see how it comes out on the other side. Each of our motherboards uses a different Super Speed USB 3.0 controller and you can find the below.

  • ASUS ROG Maximus IV Extreme-Z – NEC USB 3.0 controller
  • ASUS ROG Maximus IV Gene-Z – ASMedia USB 3.0 controller

CrystalDiskMark is a small benchmark utility for drives and enables rapid measurement of sequential and random read/write speeds. Note that CDM only supports Native Command Queuing (NCQ) with a queue depth of 32 (as noted) for the last listed benchmark score. This can skew some results in favor of controllers that also do not support NCQ.
