If you want to speed up a file transfer between two external hard drives, I can list loads of ways. For example, setting Better Performance option for external hard drives, closing running programs, connecting your external hard drives to USB 3.0/3.1 port, and more.
Method 1: Check the Better performance option for external hard drives
You can set the Better performance option of the external hard drive for a faster transfer speed. Here I will show you how to do:
Step 1: Open the Disk Management tool on your Windows 11/10 computer.
Step 2: From the left section, right-click on your external hard disk drive.
Step 3: Click on the Properties option.
Step 4: In the Properties window, switch to the Policies tab.
Step 5: In the Removal policy section, select the Better performance option.
Step 6: Under the Write-caching policy, select the Enable write caching on the device option.
Step 7: Press the OK button.
Step 8: Close the Disk Management tool.
Method 2: Connect external hard drives to USB 3.0/3.1 port
Check your computer port to see if your computer has a USB 3.0/3.1 port. If it has, you'd better connect your external hard drive to the USB 3.0/3.1 port because USB 2.0 offers transfer rates of 480 Mbps and USB 3.0 offers transfer rates of 4.8 Gbps - that's 10 times faster.
Method 3: Close running programs on your computer
Any running programs on your computer definitely result in a slower data transfer speed. In the case, you should give it a rest and close all running programs or other items when you transfer or copy files using the external hard drive to increase the data transfer speed.
If you want to transfer everything from one external hard drive to another one on your Mac, then I'd like give iBoysoft DiskGeeker a recommendation. It is featured with the Disk Clone function, which allows you to transfer files with a stable and faster speed.
