I'm having the same issue with my thinkpad t470p, only with usb drives. The transfer speed goes up to 24MB/s and that's it. I've tried different usb drives and nothing changes, updating drivers, formatting and the issue persist.
Good luck op, seems like we all need that solution
Pointless to chime in on this thread (Oops...) because people are not considering the hardware in the route the data takes, it is only as fast as the slowest hardware.
USB was always designed for multiple different devices, so not optimised for one particular task. It was the same on Windows 3.1, or XP etc with USB 1.0/1.1 ports.
3 decades of using PCs and people should at least get a smidgin of understanding hardware limitations.
Hi folks
I'm assuming the xfers aren't going via a lan - particularly wifi where half duplex (typically the default) will cut down transfer speed on any device.
Could depend on the amount of "caching" or "buffering" the I/O controller is capable of. If the SSD / other device is capable of higher speeds than the bus is capable of supplying then the device will essentially be in a "wait state" until the next buffer / block of data is ready to be transferred to the physical I/O device.
USB3 should be reasonably OK but again that will depend on how the USB subsystem interacts with the MOBO's various subsystems. You should though with a decent computer with USB3 - even a laptop - get continuous 300 - 400 Mb/s (mega bits /sec) so it would appear your speed is giving you USB2 type performance.
When buying new Disks whether SSD's, spinners or NVMe's you need also to check the computers bus speed for the Disk controller subsystems - if this is a bottleneck then it doesn't matter even if your device itself was capable of transferring data at 1000 terrabits / sec !!!. Some of these device also don't really like transferring loads of small files either - but that's another issue.
