I'm in the market for a new laptop and one of my requirements is at least two USB 3.0 ports that can offer the best speed.
I don't recall where or when, but I remember being told that when two USB ports are side-by-side or stacked on top of each other then they will operate at less than top speed if both are being used. I was told this is true for desktops and laptops.
I was told these:
Operate more slowly than these:
The reasoning given is that to save on parts, the two ports are actually just one, sharing some of the same parts underneath. Is this true sometimes, always, or never? If it is sometimes true, how can I tell the difference?
