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 PCIe SSD performance is limited to a top speed of around 1.6GBps due to the use of four PCIe 2.0 lanes. This will be sufficient for older M.2 SSDs but it will pose a significant bottleneck for newer drives such as the Samsung Polaris-based models.
USB 3.1 Performance
We test USB 3.1 performance using a pair of Corsair Force LE 120GB SSDs in RAID 0 connected to an Icy Box RD2253-U31 2-bay USB 3.1 enclosure powered by an ASMedia ASM1352R controller.
USB 3.1 Gen 2 performance is decent but it's a long way off the pace set by Intel-based competitors. The use of ASMedia's ASM1143 chipset is a limitation but it's a fair trade-off given the PCIe 2.0 lanes available through AMD's platform. ASUS' software-based boost functionality delivered an impressive performance increase.
SATA 6Gbps Performance
For SATA 6Gbps testing we use a SK Hynix SE3010 960GB SSD.
SATA 6Gbps performance is without issues.
Audio
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 was tested.
ASUS' audio solution deployed on the Sabertooth 990FX R3.0 is rated as ‘Very Good' by RMAA.
