Copy vs Clone

Speaking of copying files from one USB flash drive onto another, you may think of it as a piece of cake! It's easy, just a Ctrl C + Ctrl V can make it. But sometimes, when users say they want to copy from USB to USB, they actually need to clone between two devices. You may feel confused. What's the difference between copy and clone? When should you copy files and when should you clone devices? Here is the answer:

Copy: Copying means creating the exact same file and putting it in another location. By copying a USB flash drive to another, you only duplicate the files to another USB flash drive, not the drive's master boot record and partition tables.

Clone: Disk cloning is to copy all the contents of one disk to another disk, including the files needed to start the system. The cloning software can generate a one-to-one copy of Disk A on Disk B. This copy is fully operational. If the original disk fails, you can use the cloned disk to replace it.

Copy USB to USB

Let's make a conclusion. If you only want the files of your original USB drive, you could copy these files to the target USB. If you want an identical USB drive, you need to clone from one USB to another. In the following part, we will tell you how to copy a flash drive and how to clone USB stick.
