The Sandisk Extreme 900 drive is among the first true USB 3.1 10Gbps drives we’ve seen.įor our test, I used Sandisk’s Extreme 900 SSD, which supports USB Type C at 10Gbps speeds. However, its presence also means that any USB 3.1 Type C port is stuck at USB 3.0’s maximum speed of 5Gbps. This is actually the most common solution because it’s cheaper and doesn’t consume more power. Many PC makers simply plumb this signal into the oval USB Type C connector. This same chip controls the standard USB 3.0 Type A square ports. The last option you’ll find in many laptops is the USB 3.0 controller built into the Intel core logic chipset. The performance should be pretty much the same as you’d get out of a laptop. Intel’s pricey Thunderbolt 3 chip, which includes USB 10Gbps capabilities, is another candidate. I didn’t have a laptop with the controller, so I threw an Atech BlackB1rd MX1 PCIe card with the controller into a desktop system. It’s a USB 3.1, 10Gbps chip found in a lot of the early laptops and desktops that implemented USB-C. There seem to be two popular chips on the market today. The other major factor is the controller chip that’s used for the port. If you’re copying from an internal hard drive, for example, you won’t get near the speed of the port, because most drive interfaces can’t match USB Type C’s top speed.
Obviously, the first is your PC’s source drive. Not all USB Type C ports are created equal.Ī few key factors impact performance over USB Type C.
