Speed OK for internals

Got this board to connect an external USB 3.2 RAID array. I'm nowhere near the advertised speeds, but that's most likely due to the limitations of the PC I installed it on. and I've never had much luck with USB generally hitting advertised speeds. The speed is better than the onboard USB 3.0 ports, but I only get about 35MB when copying files that are about 1TB. Built-in ports are about half as many. Now that I've backed up the PC I need to look at a new PC that can hit faster speeds and I'll update the review at that point.

Pros
