Can I Clone 2TB HDD to 1TB SSD?

Yes, you can clone a larger HDD in a different size to a smaller SSD successfully with certain conditions as listed here:

  1. 1. Used space on the hard drive is equal to or smaller than the capacity of SSD.
  2. 2. New SSD is properly installed and initialized on PC.
  3. 3. Turning to a reliable disk cloning software.
  4. 4. Making cloned SSD bootable if it's an OS drive.

So how to make sure that the whole process goes smoothly? Follow the complete guide below to start cloning and upgrading your 2TB hard disk to a faster and more reliable SSD now.

Guide 1: Purchase a New SSD

Note that if you've already got 1TB SSD, jump to Guide 2. This guide is designed for those who haven't selected a new SSD yet. 

Here we compared three types of SSD disks - SATA, M.2, NVMe and want to give you a moderate suggestion on selecting a new SSD

Image of SSD

Comparison SATA SSD M.2 SSD NVMe SSD
Interface SATA, 3.5 or 2.5 inch enclosures SATA, PCI Express PCI Express
PCI Express 600 MB/s  1500+ MB/S 3.5 GB/s
Price of 1TB Capacity $90-$200 $100-$200 $100 - $400

Which type of SSD should I purchase? Take the next two factors into consideration, and you'll get the answer:

  1. 1. What type of SSD slot does your computer support?
  2. 2. What is your max budget for a new SSD?


  • If your computer only supports the SATA interface, you can only choose a SATA SSD. 
  • If your computer supports both SATA and PIC Express interfaces, your budget for an SSD can help you make the decision. Normally, we suggest that you purchase a faster SSD if the cost is nearly the same.

Also, you need to confirm the used space on your 2TB disk is equal to or smaller than 1TB. If the hard drive data exceeds the total space in SSD, we suggest that you prepare an even bigger SSD.

Guide 2. Install and Initialize 1TB New SSD on Windows Computer

Once you get the 1TB SSD home, you can now follow the guide here to install and initialized the SSD properly on your computer.

Here are the detailed steps:

Step 1. Turn off your computer.

Step 2. Pick a proper screwdriver to open your computer or laptop case.

For a Laptop computer, use No.1. For a Desktop computer, use No.2.

Select the right screwdriver

Step 3. Install the new SSD on the computer.

On a laptop computer, find the SSD slot, insert the M.2/NVMe SSD, and fasten it with screws.

Insert M.2/NVMe SSD

On a desktop computer, plug the SATA SSD via a power cable and SATA cable into the computer motherboard.

Install SATA SSD

Step 4. Restart PC and initialize the SSD.

To ensure the 2TB HDD to 1TB SSD cloning procedure goes smoothly, it's wise that you initialize the new SSD to the same disk type as the source HDD. 

Here is how to do so:

1. Go and check the disk type of the 2TB HDD:

Go to Disk Management > Right-click on the source disk and select "Properties" > Go to Volumes and check its disk type:

Check source disk type

2. Now, you can initialize the 1TB SSD:

In Disk Management > Right-click on unallocated new SSD and select "Initialize Disk" > Select the disk type as the same as 2TB HDD - MBR or GPT.

Initialize SSD

After initializing the new SSD, you can now move to Guide 3 and start cloning the disk.

Guide 3. Download Disk Cloning Software & Clone 2TB HDD to 1TB SSD with Ease

Tool: Disk cloning software - EaseUS Partition Master

Estimated Cloning Duration: 30minutes - 1hour

Mostly, the speed of disk cloning software won't be much different. The key factor that decides the disk cloning duration is how much data that you have on the source disk. The bigger size of the data, the longer it will take for cloning from 2TB HDD to SSD.

There are many disk cloning software available online for you to upgrade and replace computer hard drives. And here, in this part, we would like to recommend you taking EaseUS Partition Master for help.

Guide 5. Make Use of Old 2TB Hard Drive, Optimize 1TB SSD

  1. 1. Clean up and wipe it for sale.
  2. 2. Empty and repartition it for reuse.
  3. 3. Optimize SSD performance.

  • It won't hot image your drives or align them, but since it's coupled with a partition manager, it allows you do perform many tasks at once, instead of just cloning drives. You can move partitions around, resize them, defragment, and more, along with the other tools you'd expect from a cloning tool.
