To test the USB 3.0 ports on the Athena Aura, I plugged in an OCZ Trion 150 SSD via a SATA-to-USB 3.0 5Gbps adapter, which uses the ASMedia ASM1053 controller. We reviewed the SSD HERE, finding it delivers good speed at a budget price.
Most importantly, it is capable of saturating the USB 3.0 bus, allowing us to test the speeds the USB 3.0 ports deliver. To test this, I ran both CrystalDiskMark and ATTO Disk Benchmark on the Trion 150 drive.
As expected, we see speeds in excess of 400 MB/s which indicates that the USB 3.0 interface is just fine.
