To test the USB 3.0 capabilities of the Asus Z87-A motherboard, we use one of the fastest drives we have – the Patriot SuperSonic Magnum 256GB.
We reviewed this way back in February last year.
Performance from the USB 3.0 ports is impressive, almost hitting 300 MB/s in the sequential read test.
Peaks around 270 MB/s in the read test, close to the performance in CrystalDiskMark.
