Results: HD Tach USB 3.0
The Samsung 840 Pro was used in the Sharkoon USB 3.0 dock for this particular test. Since the SB950 does not have a USB 3.0 controller onboard, we are testing the added chips. The Asus uses the ASMedia 4 port controller while the MSI uses the VIA 4 port unit.
The VIA controller is quite a bit faster in average, max, and min throughput. It achieves this level of performance by leaning HEAVILY on the CPU. 2% load on the ASMedia controller vs. a whopping 17% on the VIA controller is simply astounding. We don’t often see a peripheral using that many CPU cycles for I/O operations (unless your name is Fusion I/O).
