How Long Does it Take to Clone a Drive?

How long does it take to clone a drive?

Nowadays, cloning a hard drive is common to see. You might want to upgrade to SSD or a larger drive to speed up your computer, or you just want to clone a drive as a backup. No matter which situation you are in, you may be curious about "How long does it take to clone a drive?" It will be hard to give you an exact answer because it is determined by a number of factors. Generally speaking, the time it takes to clone a hard drive depends on your cloning speed and data size.

Let's make an assumption. If your cloning peed is 100 Mb/s and you want to copy a drive with 500GB data on it, in such case, about 90 minutes will be spent on the cloning process. Further to say, cloning the same 500 GB drive but at 50 Mb/s would double the cloning time to nearly three hours. Therefore, it's easy to understand that the faster the speed is, the shorter the clone will take, and the larger the size of the data is, the longer it will take.

However, you may encounter a "cloning hard drive takes forever" issue, causing you to spend several hours or even longer cloning a hard drive. Here is a live example:

"I am planning on cloning my hard drive to an external SSD as it is running so slow. I notice that the cloning speed starts fast but then stuck at 15% for about 5 minutes. How long does it take to clone a hard drive? I have been working on this issue for hours. Is it going normally? How can I make it faster? I am open to any suggestions. Thank you very much."

▌Why does cloning a drive take so long?

But why does it also take so long to clone a hard drive when your data is little and clone speed is fast, this is because there are many other factors that may affect the speed of cloning, you may be inspired by the following contents.

✦ The USB connection has slow speed. If you are cloning your computer to an external hard drive or SSD, the health of the USB cable will affect the speed of cloning. When the port is not in good health, the disk will be slow to read and write.

✦ Your computer configuration is too old. If you don't update your computer configuration to the newest, it will certainly slow down the copy of hard drive. Thus, it's not a bad idea to upgrade your computer to Windows 11, the newest Windows operating system.

✦ There are bad sectors on the source disk. During the cloning process, it will take a longer time to recognize and clone the contents on the bad sectors. That's the possible reason why the clone sometimes stucks or even fails.

✦ There are read/write issues on the target disk. If the destination disk is not new or it has been used for a long time, it has the risk of read/write speed issues, directly influencing the cloning speed. Therefore, you'd better format the target disk before using it to guarantee the good state of the disk.

✦ The cloning tool you apply doesn't work. If the cloning utility you selected is not professional enough, it will also lead to a slow cloning process.
