Why does cloning a hard drive take so long? How long does it take to clone a hard drive?

Question - Why does cloning an HDD to an SSD take so long?

"My Windows 10 cloned HDD/SSD is slow. The cloning process seems to take forever. I want to clone my 256GB HDD to my external HDD. The copying speed started fast, then slowed down for no reason. I'm using Acronis True Image WD Edition. I started cloning yesterday, and it's been 24 hours, but the progress is only at 18%. Is this too slow? What should I do?"

Analysis - How long does it take to clone a hard drive?

How long does it take to clone a hard drive? That depends on the amount of data on the hard drive that needs to be cloned. This is the most important factor in estimating how long a cloning process will take. The method you use to clone the drive is also critical. So, it's good to know that when looking at drive transfer rates, the quoted speeds are “burst” rates, not sustained transfer rates.

A Seagate hard disk might be rated to transfer data at 100 megabytes per second (MBps), but it will not transfer a full gigabyte at that rate. The new high-speed SATA disks are rated at 300 MBps, but you should halve that number when calculating how long a copy will take.

So, if your cloning speed is 100 MB/s, it would take approximately 17 minutes to clone a 100 GB hard drive. If it takes 87 minutes to clone 500 GB of data, that's the average speed. By now, you should have got the answer to how long does it take to clone a 500 GB hard drive or how long does it take to clone a 1 TB hard drive.

How to Fix Slow Cloning of HDD/SSD (6 Solutions)

SSD or HDD cloning taking too long? Learn how to clone a hard drive or SSD easily and quickly. Use disk cloning software, the best disk clone tool, to clone HDD/SSD and create a bootable Windows 10/8/7 clone.

Six Reasons Why Cloning Takes So Long

Why does cloning take so long? What are the main reasons? Our analysis suggests six.

1. The source disk is old and has bad sectors. If your hard drive has bad sectors, the cloning process will be affected. This is because bad sectors on the hard drive can slow down the cloning process and even cause it to fail.

2. The target disk has bad sectors or read/write issues.

3. The data volume is too large, which can lead to excessively long cloning times. In other words, the larger the data volume, the longer it will take.

4. The USB connection is too slow for reading or writing. The USB cable itself can affect transfer speeds.

5. Your computer is outdated. An old setup can slow down any operation.

6. Tools. Disk-cloning utilities are not good enough, making the process a snail's pace.

6 Solutions - How to Fix Slow Hard Drive Cloning Issues

With the causes and triggers identified, we can fix the slow cloning process. Below are six solutions to speed up HDD or SSD cloning.

Solution 1: Wait patiently

If you're cloning a lot of data from a hard drive or other device, it can take a while – 17 minutes to clone a 100 GB drive at 100 MB/s, for example. You can do the math and check your results when it's done. If cloning just 100 MB of data takes an hour, read on.

Scanning for bad sectors can take a long time, during which you might try using a disk-cloning utility.

Solution 2: Use a SATA connection

There are two types of hard drive interface for computers: PATA (Parallel Advanced Technology Attachment), also called IDE, and SATA (Serial Advanced Technology Attachment). If your cloning process is slow, switching to SATA can be a good way to solve this problem. PATA transfers data at speeds of 66/100/133 MB/s, while SATA transfers at 150/300/600 MB/s. The faster speed of SATA allows for quicker program loading and faster transfer of pictures and large documents.

Solution 3: Use a Boot Disk Cloning Tool

If cloning a 500GB hard drive takes a whole day, that's too slow! If upgrading USB 2.0 to USB 3.0 or SATA can solve the problem, then it's fine. If the cloning process is still slow, you can use a super fast disk cloning software - AOMEI Backupper Disk Copy Home Edition.

It's a simple yet secure disk cloning tool that can help you transfer data and upgrade your hard drive at lightning speed. It assists you in cloning a hard drive with multiple partitions and resizing partitions during the cloning process. It employs advanced sector-by-sector cloning technology, enabling you to clone a hard drive with bad sectors. Furthermore, it significantly boosts cloning speed – get it now!

How to Clone a Hard Drive

If you're unfamiliar with the details of cloning, watch this video on how to use disk cloning tools. And for help troubleshooting if your clone is running slowly, check out this video tutorial.

How to Clone Your Hard Drive to an SSD

 

Step 1: On a healthy Windows computer, download, install, and run the Disk Copy utility. Connect an external storage device, such as a USB flash drive or an external hard disk, to the computer. Click “Create Bootable Disk.”

Step 2: Select “USB,” choose your device, and click “Create.”

When it's done, you'll have a bootable disk.

Step 3: Connect the bootable disk USB and your new SSD/HDD to the computer you want to clone the disk to, and set the boot order in BIOS to boot from the bootable disk.

Step 4: In the Disk Clone tool, click on “Disk Mode,” then select the source disk that you want to copy or clone. Click “Next” to proceed.

Step 5: Select the target disk to which you wish to clone/copy the old one, then click “Next” to proceed. If prompted, confirm that you want to wipe out data on the target disk.

Step 6: Review and edit the disk layout, selecting either “Auto adjust to disk,” “Match source,” or “Edit disk layout.” “Auto adjust to disk” is recommended.

• The "Copy source" option will copy cloning the partition layout from the source disk to the target disk.
• The "Edit disk layout" option lets you manually adjust or move the partition layout on the target disk.
• If your target disk is an SSD, make sure to check the "Target is SSD" option.

Click Continue to start disk cloning or disk copying right away.

Solution 4: Check CPU and memory usage

To check the CPU or disk usage:

Step 1: In the Windows search bar, type “Task Manager” and select “Task Manager.”

Step 2: Look under the Processes tab to see what's causing high hard disk or CPU usage.

If the progress is too slow, you may want to use a Disk Copy bootable disc to clone it, or clone it on a more capable computer.

Solution 5: Replace the target disk with a healthy one

Another way to speed up the clone is to replace the target disk with a good one. If the target disk itself is the problem, you'll need to buy a new one or replace it with a known good one.

Step 1: Buy a new hard drive or SSD.

Second, plug it into your computer via a SATA interface.

Step three: Use a disk-cloning tool to clone your drive to the new one.

Solution 6: Try a disk cloning tool

The right tool can make all the difference. Disk Copy is the best disk cloning software that safely copies data from one disk to another in Windows. It can:

• Clone HDD to SSD
• Clone old hard drive to new one
• Download it and clone HDD or SSD at a fast speed

Conclusions

Trying out these methods can easily resolve the “Cloning a hard drive takes too long” error. The connection cable, disk condition, and disk cloning tool can all affect cloning speed. Choosing the right connection cable and disk cloning tool will give you the best results with minimal effort. AOMEI Backupper Disk Clone is a tool that can help you quickly clone a hard drive or SSD.
