Cloning HDD/SSD Takes Forever in Windows 10

"My Windows 10 is really slow to clone my HDD/SSD. It seems that it cloning process is taking forever. I want to clone a 256GB hard disk to my external hard drive. The copying speed starts fast then drops down without any reason. I'm using Acronis True Image WD Edition. I started the cloning process yesterday 24 hours ago and it's only 18%. Is this going too slow and what should I do?"

How Long Does It Take to Clone a Hard Drive

Establish how much data is on the hard drive to be cloned. This is the single most critical factor in estimating the time to clone a hard drive. It is also crucial to determine the method that will be used to clone the drive. So we must know that when reviewing drive transfer rates, keep in mind that the rates quoted are "burst" rates, and not sustained transfer rates. 

A Seagate drive might claim that it can transfer data at 100MBps (Megabytes per second) but it will not be able to move a gigabyte's worth of data at this speed in the real world. This reality holds true for the newer high-speed SATA drives which claim to be able to transfer 300MBps (Megabytes per second), but the real transfer rates that should be used to calculate a clone process should be lowered to roughly one half of that speed. So if your cloning speed is 100MB/s, it takes about 17 minutes to clone a 100GB hard drive. If your cloning process takes 87 minutes to clone 500GB data, it is normal speed.

How to Fix the "Cloning hard drive very slow" Issue

What if the process takes a whole day for cloning a 500GB hard drive? It is indeed too slow! If changing your USB 2.0 to 3.0 helps you solve the problem, you can let it be.
