At that time, although it was advertised as usb3.0, in fact, the speed limit for uploading large files was always around 50-80MB/s
After updating 18.4 today, it can probably run between 100-300

Anonymous640 Apr 2, 2025Only some software services that come with Apple can reach peak speeds. Usually, the speed of using MacBook Finder to back up mobile phones or import photos to computers can reach about 1GB/s; But the speed of dragging and dropping files is only 80MB/s (the Finder is slow to drag files to the iPhone and reverse) Did you use a high-speed USB cable? The built-in line is 2.0 Just recorded a prores video, 13GB, imported to the computer via Photos for tens of seconds;
