Hi,

I own a Maximus Formula motherboard. Currently, i have the USB 3.0 card in the secondary PCI-E video slot. I would like to move it to the black PCI-E 1.0x slot, because my two USB 3.0 hard disk drives are resting too close to the floor. Would doing effect speed of the USB 3.0 HDDs?

Thanks
NBK

A SIIG USB 3.0 PCI-E card. It is an 1x card.

In that case it should run no slower when in a 1x pcie slot.
Max bandwidth of 1 pcie channel is 5Gbps and max for USB3 is 4.8Gbps.
There are no USB3 devices which get anywhere near that yet.
A typical USB3 hard drive can only sustain about 1Gbps (ie
about 120 MB/S) although it may have tiny bursts faster than that
(not something you'll notice in the real world.)
