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 was unrestricted while the M.2 shield did its job in preventing thermal throttling under extended heavy loading. That entailed running the ATTO benchmark three times (almost ten minutes) without a break and then recording the maximum temperature at the end.
We test USB 3.0 and 3.1 performance using a pair of Transcend SSD370S 512GB SSDs in RAID 0 connected to an Icy Box RD2253-U31 2-bay USB 3.1 enclosure powered by an ASMedia ASM1352R controller.
USB 3.0 performance was as expected, USB 3.1 fell 100MB/s in peak read below expectations but this seems to be a reoccurring bug with some X299 motherboards and Windows that affects different motherboards with no clear pattern.
SATA 6Gbps Performance
For SATA 6Gbps testing we use an OCZ Trion 150 480GB SSD.
SATA performance is par for the course for X299.
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 was very good, finishing in second for every test out of all motherboards that were benchmarked. 6 Excellent, 1 Very Good and 1 Good rating is standard for the Realtek ALC1220 codec used and the use of a Texas Instruments operational amplifier and high quality audio capacitors brings out the best of that codec.
