USB 3.0
To test the USB 3.0 ports on the BRIX UHD, 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.
Testing USB 3.0 bandwidth is more a case of ensuring speeds are where they should be – and the speeds here are right at the limit of the USB 3.0 interface.
PCIe M.2 slot
To test the bandwidth of the PCIe slot in the BRIX UHD, I ran both CrystalDiskMark and ATTO Disk Benchmark on the 512GB Samsung 950 Pro PCIe SSD.
Both tests indicate that the 950 Pro was able to hit its maximum speeds of 2500 MB/s read and 1500 MB/s write respectively. We can thus be confident the PCIe bus link for the M.2 slot is operating successfully.
