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 is as expected for the 32Gbps PCIe 3.0 X4 link and the M.2 heatsink does a good job of keeping thermals out of the throttling zone, even under prolonged (10 minutes +) stress testing. Temperature and performance results were identical, within margin of error, for the second M.2 slot which is also cooled and also supports a PCIe 3.0 X4 link.
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 were par for the course.
SATA III 6Gbps Performance
For SATA 6Gbps testing we use an OCZ Trion 150 480GB SSD.
SATA III performance is nothing out of the ordinary.
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.
The audio performance of the Realtek ALC1220 codec is excellent and this test just confirms it. ASUS has implemented the codec well for a mid-range motherboard and the dual operational amplifiers is a nice touch for headphone users too.
