CrystalDiskMark 3.0.1 Results

CrystalDiskMark is a benchmarking utility designed to quickly gauge the performance of a storage drive. It measures sequential read and write speeds and random 512KB, 4KB, 4KB (queue depth = 32) read and write speeds.

USB 3.1 paired with ASUS USB 3.1 Boost (Turbo mode) was the clear winner here. It resulted in around a 35% increase in sequential read speeds a 32% increase in sequential write speeds as compared to USB 3.1 with Normal mode enabled in the USB 3.1 Boost utility. However, this lead narrowed and even fell away when it came to the random 512K and 4K read/write tests.

Given that everyday users are not likely to disable CPU C-States and EIST, we also ran these tests with the power savings settings in BIOS enabled to get an idea of the performance difference. What we got were sequential read/write numbers in the range of 455MB/s for USB 3.1 (Normal mode) and 670MB/s for Turbo mode, so users who run their boards straight out of the box without tweaking the settings can expect figures in this range.
