USB Type C speed test: Here’s how slow your laptop’s port could be - rodriguesthenoth99

USB Typecast C is the challenging new port that began appearing in laptops, tablets, phones, and opposite devices well over a year ago, simply we had no real way test its throughput performance until in real time. Thanks to Sandisk's Extreme 900, we're finally able to push that lilliputian reversible larboard to its limits. To coif that I gathered up no fewer than eight laptops equipped with USB Type C ports, and threw in a background PCIe card for good measure too.

What your USB-C port isn't telling you

USB Type C is supposed to be a universal standard, but it's just universally confusing. A USB Type C port fire test at either 5Gbps or 10Gbps and still be tagged USB 3.1 past the laptop maker. USB Type C even technically supports USB 2.0 speeds at a pathetic 480Mbps. So when you see a USB Eccentric C port, the only assumption you can make is that its transfer speeds stool vary from as double-bass atomic number 3 480Mbps to as high as 10Gbps.

To sloughy things fifty-fifty promote, Intel's Thunderbolt 3 technology uses the same USB Type C port for transfers over PCIe. It'll too support USB 3.1's 10Gbps.

Thither's a longer discussion to be had about Thunderbolt 3 and video-impossible abide terminated USB Type C, just that's for another day. I did, however, write about Tycoo Delivery and non-indeed-universal charging on USB C (hint, IT's a little of a mess).

Not all USB Eccentric C ports are created quits.

What's probably in your laptop

A few key factors impact performance terminated USB Typewrite C. Obviously, the first is your PC's informant drive. If you'Re copying from an internal disk drive, for example, you won't get near the f number of the port, because near drive interfaces can't match USB Type C's tip travel rapidly.

The other major factor is the controller chip that's used for the porthole. In that location appear to be two popular chips on the market now. The first is ASmedia's ASM1142. It's a USB 3.1, 10Gbps chip found in very much of the inchoate laptops and desktops that implemented USB-C. I didn't have a laptop computer with the controller, so I threw an Atech BlackB1rd MX1 PCIe card with the controller into a background system. The performance should equal beautiful much the same as you'd get out of a laptop. Intel's pricey Thunderbolt 3 break away, which includes USB 10Gbps capabilities, is another candidate.

The last option you'll find in many laptops is the USB 3.0 comptroller built into the Intel nucleus logic chipset. This same chip controls the regulation USB 3.0 Group A square ports. Many Personal computer makers simply plumb bob this bespeak into the oval-shaped USB Type C connector. This is really the most rough-cut solvent because it's cheaper and doesn't run through to a greater extent power. However, its presence also means that any USB 3.1 Type C port is stuck at USB 3.0's maximum speed of 5Gbps.

The Sandisk Extreme 900 drive is among the first true USB 3.1 10Gbps drives we've seen.

How we tested

For our test, I used Sandisk's Extreme 900 SSD, which supports USB Case C at 10Gbps speeds. Sandisk builds this 2TB drive away wiring ii M.2 SSDs in RAID 0 internally. Information technology's pretty blistering fast for a USB drive. Plugging into each laptop computer's USB Type C port, I so ran the American Samoa SSD storage benchmark for thoroughgoing sequential transfer speed across the port.

The results speak for themselves in the bench mark graph below, ranked from highest- to lowest-performing. Each entry lists the laptop computer make and model along with the USB controller.

We hierarchical more than hexa laptops based happening their USB Type C performance.

No surprise, the laptop makers that resorted to the lowest-cost pick (wiring the included Intel USB 3.0 5Gbps accountant to the USB Typewrite C left) leave you, well, 5Gbps performance. I didn't prove a 12-in MacBook because Equally SSD doesn't run in Operating system X, but it uses the same controller, soh expect it to be corresponding to the others here.

Of greater concern is the performance of the 10Gbps chips: the ASMedia Saratoga chip and the Thunderbolt 3. In the graph, that's represented by the two Dell XPS laptops for Thunderbolt and the ASMedia chip in the desktop. In these tests, the ASmedia has a svelte edge connected the Thunderbolt 3 controller. Vendors have told me their own internal examination backs that up.

The Samsung Notebook 9 Pro appears to use but the USB 3.1 dowry of an Intel Bolt 3 controller.

There's one more rather interesting wildcard in the essa, and that's the Samsung Notebook 9 Pro laptop. This 15.6-inch laptop takes a rather unusual approach with its USB Eccentric C port wine by integrating an Intel "Alpine Ridge" Thunderbolt 3 chip, but opting to purpose only the USB support in it. In the device manager, IT smooth shows improving as an Intel USB 3.1 control as you give the axe see from the riddle chatoyant supra.

Samsung officials confirmed the laptop computer doesn't support Thunderbolt 3. I even proved it with an Akitio Thunderbolt 3 drive to confirm. Why Samsung did this I just don't know.

I do cognise that the performance was strangely slower. It was faster than the featureless-jane  USB Type C port that uses the Intel chip, but slower than the ASMedia and full Thunderbolt 3 laptops. Weird.

Conclusion

One take the benchmark graph should tell you that there are factual hard benefits to having a full USB 3.1 10Gbps port in a laptop operating theatre desktop PC. The most obvious is the time regenerate ready and waiting for files to copy to your USB drive. The some other is taking rumbling vantage of that great new USB 3.1 10Gbps motor you just bought. As USB Type C ports start appearing on more machines, IT'll pay to read the close print in the specs.
