To test the USB 3.0 ports on the SuperNova, 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 we would expect, the results show the USB bus is operating right at the limit of the 5Gbps ceiling.
