How Long to Clone a 4TB Hard Drive?

I keep my backups on a 4TB hard drive. How long would it take me to copy all the 4TB of data to another 4TB external hard drive? Is there any better way to do such a job? If so, please tell me how to do it.

Since your drive could be faster or slower, giving you a precise response will be challenging. At an average speed of 100-120 MB/s, it will take about 9-11h to clone a 4TB hard drive.

Following are the times for transfers between 90 and 140 megabytes per second:

  • 90 Mb/s - about 12.5 hours
  • 100 Mb/s - about 11 hours
  • 110 Mb/s - about 10 hours
  • 120 Mb/s - about 9.2 hours
  • 130 Mb/s - about 8.5 hours
  • 140 Mb/s - about 8 hours

Other factors, such as the USB cable, hardware state, cloning tool, disk kinds, faulty sectors, etc., will also affect the cloning time and the transfer speed. Make sure your hardware and wires are in good shape before cloning. For example, neither the source nor the target hard drives have faulty sectors.

It may also be much faster if the drive is partially full. You should also consider the drive's speed, which I set equal to the drive being cloned from for these calculations. Depending on which is slower, you must use the drive's read or write speed while copying data.

To clone your 4TB hard drive, you must use a professional cloning tool because Windows does not have such a tool. Under such circumstances, EaseUS Todo Backup comes in handy. Its straightforward and user-friendly design makes it a great hard disk cloning application that may assist you in swiftly finishing the cloning procedure. It can help you clone a hard drive in Windows 11 and clone HDD to SSD. You can also utilize it to back up the different data on your computer, such as files, systems, disks, etc.

You should ensure you have enough time to complete the cloning process once you decide to clone the 4TB hard drive. Choosing the right cloning program can help you to finish the task easily and quickly.
