USB-C data speed rate tranfer of X270

2021-05-31, 4:09 AM

Hello,

I use X270 laptop, I'm wonder that USB-C data speed rate is 2.0 or 3.0 version ? I've test on CrystalDiskMark software, the result is about 40 MB/s(read-wirte). That is correct ? as the result, the USB-C is mean type of port, not about version of USB ?

so it mean that USB-C of X270 is version 2.0 ?

 

Please,
Thank you.

Hi Lorenzo_Lenovo,

I've downloaded UsbTreeView_Win32 from https://www.uwe-sieber.de/usbtreeview_e.html to check version of USB-C on my laptop, the result as show below.



It show USB version 2.1 and the speed that I try test is about 40 MB/s. I test with m.2 to USB-C device and use software for testing.

Please help,

Best regards,
Thank you.

Hello,

 

USB-C is a single physical connector which supports several different signalling protocols (USB 1.1, 2.0, 3.0, 3.1, 3.2, 4.0; and Thunderbolt 3 and 4).

 

In order for a USB-C port on a computer to run at the fastest speed the port supports, the device plugged into it must support that same speed, as must the cable connecting the device to the computer's port.

 

Judging from the screenshot, it appears either the device or the cable (or both) plugged into the ThinkPad X270 only operate as USB 2.0 speeds.

 

I would suggest that you try testing with a different device and cable and see if you notice an improvement in speed.

 

Regards,
