SATA
For SATA 6Gb/s testing we use a Kingston HyperX 3K (SandForce SF-2281) SSD.
SATA performance is as expected. Asus' Z170-fed ports deliver leading results, while the ASM1061 implementations are also the joint-fastest of all competitors but are significantly slower than Z170 alternatives.
USB 3.0
We tested USB 3.0 performance using the Kingston HyperX 3K SSD connected to a SATA 6Gb/s to USB 3.0 adapter powered by an ASMedia ASM1053 controller. The test system uses Windows 7 with SP1 as the OS.
Asus wins the day when it comes to USB 3.0 transfer rates using the Windows 7 OS. This is thanks to Asus' UASP-activating tool that competing manufacturers do not offer.
Audio
We use RightMark Audio Analyzer (RMAA) to analyse the performance of the motherboard’s onboard audio solution. A sampling mode of 24-bit, 192 kHz was tested.
RMAA rates the Sabertooth Z170 Mark 1 motherboard's general audio performance as ‘Excellent‘. Frequency response, noise level, and dynamic range numbers are particularly impressive.
