For me it's usually *after* Christmas season, but whatever works :)

I can imagine it. For a controller, negotiating USB 3.0 / XHCI protocol
with a device is one thing, delivering the expected bandwidth is
another. I've toyed around with enough cheap IDE and SATA adapters to
know it takes more than a logo on the packaging to get decent throughput.

Also, the bus needs to offer enough bandwidth to avoid being a
bottleneck. Theoretical maximum speed for USB3 is 5 Gbits/s, that's a
bit more than 2 PCIe lanes can sustain, so you'll want an adapter than
plugs into a full-sized PCIe connector, unlike the Syba one.

Hope this helps,
