What's the Fastest Way to Clone External Hard Drive

Q: How to clone an external drive to another on Windows 10 in a quick way?

"One of my friends complained that it took him a whole three hours sitting in front of a computer to copy a 500 GB external hard drive to another 1 TB external drive for the purpose of keeping a backup. He used Ctrl C + Ctrl V to back up external hard drive to another external drive! No wonder the process took so long. So, is there any quicker way to clone the external drive?"

It's a good way to duplicate an external drive for data transfer from one external drive to another. But if the files and installed programs on the external hard drives you want to transfer are too large, it will take you quite a bit of time, as described in the above scenario.

Then, what's the fastest way to clone an external hard drive to another external drive (HDD or SSD)? Use EaseUS Disk Copy. The super-fast SSD/HDD raw copy tool for disk copy, clone, upgrade, replacement, or simply backup.

Why Do You Clone an External Hard Drive to Another

"I have an external hard disk and want to back it up to another external drive before performing file system operations on it. But all questions and articles I have found so far on Google have been for cloning an external drive to another external drive. It has multiple partitions of different file system types. I intend to clone it exactly to the second external drive. How do I clone my one external drive to another or transfer files from one external disk to another?"

Many users choose to clone an external hard drive to another for backup purposes, which can help add an extra layer of protection to the external drive. You still have a duplicate copy if your external disk is damaged or lost. However, cloning an external drive and backing up an external disk are not exactly the same.

To back up an external drive, you will get a compressed image file, and the system files can not be copied to another drive. Cloning a hard drive means your target disk will have everything the same as your source drive, including the data and disk layout. You may want to clone a hard disk for a variety of reasons.

  • Creating a backup. Disk cloning can help create a fresh copy of your hard drive, which can be used as a backup in the event of hard disk failure or data loss.
  • Migrating operating system. If you want to transfer an OS to a new hard drive, you can clone the old drive. Cloning can help you transfer everything from one hard drive to another.
  • Transferring data on the old drive to a new computer. You can clone the old drive to the new one when using a new PC. Therefore, you can have your data and settings the same as the old drive.


EaseUS Disk Copy allows you to easily clone an external hard drive to another external hard drive, clone an internal boot hard drive to a new hard drive, or clone hard drive in the WinPE environment. Furthermore, you can also use simple-to-use and powerful hard drive cloning software to clone operating system partitions to SSD, transfer files/data from one hard drive to another, etc. If you want to replace a laptop's hard drive and reinstall the operating system, it can also suit you well.
