ATTO Disk Benchmark
The ATTO disk benchmark is a Windows-based utility for testing storage performance of any storage drive or controller. We use the default benchmark setup.
M.2 PCIe Performance
For M.2 testing we use a Toshiba OCZ RD400 256GB M.2 PCIe NVMe SSD.
M.2 performance easily exploited the maximum performance potential of the benchmark drive. Thermal performance was very respectable too, due to the rather large M.2 heatsink assembly and KitGuru tested temperatures in the high 50s after extended heavy loading. Given the throttle speed is around 75-80 degrees Celsius most high performance drives should have no trouble performing consistently well with this motherboard.
We test USB 3.0 and 3.1 performance using a pair of Transcend SSD370S 512GB SSDs in RAID 0 connected to an RaidSonic Icy Box RD2253-U31 2-bay USB 3.1 enclosure powered by an ASMedia ASM1352R controller.
USB 3.0 and 3.1 performance was roughly in line with expectations noting that the USB 3.0 controller was the X470 chipset whilst the USB 3.1 controller was the ASM1142 controller, we were not able to test the X470 chipset USB 3.1 port.
We have, however, witnessed better USB 3.1 performance on Intel 300-series motherboards to the tune of an extra 150MB/s.
*Note that the ASRock X470 ITX motherboard had compatibility issues between its USB 3.1 port (X470 chipset USB 3.1 controller only) and the ASM1352R RAID box and thus we were unable to test using our standard equipment. We did manage to test with a single USB 3.1 (ASM1351) to SATA device and achieve speeds much faster than USB 3.0 just to validate the port was functioning correctly.
SATA III 6Gbps Performance
For SATA 6Gbps testing we use an OCZ Trion 150 480GB SSD.
SATA III performance was as expected.
Rightmark Audio Analyser is a freeware benchmarking utility designed to objectively test the performance characteristics of audio solutions. We setup a line-in line-out loop and execute the record/playback test before generating the results report you see below. A sampling mode of 24-bit, 192 kHz is tested where available. If unavailable the closest alternative operating mode available is used and clearly marked.
Audio performance returned a score of Very Good, with 7 Excellent and 1 Very Good rating in each of the main categories. The performance is in line with what we’ve seen from other Realtek ALC1220 codec based motherboards including Z370 motherboards using the same codec.
