USB 3.0 Performance
Asrock's Mini-ITX boards were on a level plane when measuring USB 3.0 performance with our program copy test, being separated by a few MB/s.
For some reason, the A75M-ITX struggled with our game copy test, maxing out at 100MB/s while the Z68M-ITX/HT attained 171MB/s reads.
CrystalDiskMark's sequential read and write performance was virtually identical across both boards as they cracked 180MB/s reads and writes.
