Can I clone a 500gb HDD to a 250gb SSD?

“I just bought a 250GB Samsung SSD and want to migrate my OS and all applications from the original hard drive to new SSD. My HDD has a total capacity of 500GB and is partitioned, but only 193GB of it are used. Is it possible to clone a 500GB HDD to a 250GB SSD? Any kindly advise will be appreciated, thanks in advance.”

Why clone 500GB HDD to 250GB SSD?

First for sure, your SDD is a great upgrade for hard disk. Why do I say that? Here are two main reasons.

  • Faster speed. Compared with HDD, Windows, application and games will be faster on an SSD. Because SSD does not contain any movable parts.

  • High data security. Since there is no moving part, your data will be much safer. knocking or dropping the drive will not cause any accidental damage.

Besides, SSDs still have other advantages, such as, lighter, quieter, more durable, produce less heat and consume less power.

How do I clone larger HDD to smaller SSD?

Speaking of cloning larger HDD to smaller SSD, many users may encounter the case above. Here, I’ll introduce 2 trust and reliable ways.

  • Backup larger HDD and restore image to SSD. Considering the way to transfer the 193GB data scattered in different partitions from larger HDD to smaller SSD, you can create HDD image and then restore the backup image to the SSD

  • Use a free but professional disk cloning software. This means, a software can clone larger drive to smaller drive successfully and ensure secure boot, as long as the used space on larger drive is less than or equal to SSD.

In sum, both ways can realize this goal. But I have to say that the first method create an archive of a hard drive and requires another device to save the image, which should be a tricky operation. So, you'd better use a professional disk cloning software like AOMEI Backupper to clone 500GB HDD to 250GB SSD. And I’ll show you the detailed steps later.

Free but professional disk cloning software - AOMEI Backupper

Generally speaking, disk clone creates an exact copy of the original disk so that you should make sure the destination disk is the same size or larger than the original one.

If your situation is similar to the above case, you are very luck. Because SSDs have enough space to hold data on the HDDs, which is the only requirement when cloning larger HDD to smaller SSD with AOMEI Backupper.

In the above case, the used space of the 500GB HDD is 193GB which is no more than 250GB of your SSD, so you can clone 500GB HDD to 250GB SSD with this software.

Then, I’ll introduce you some useful features of AOMEI Backupper:

  • Fully support cloning all branded disk, such as, Samsung, Dell, HP, SanDisk, etc. Some branded disk will come along with a cloning software, such as, Samsung Data Migration software, but it only clone corresponding SSD listed in the user manual.

  • Clone larger disk to smaller disk regardless of disk size. That’s to say, you can clone 500GB HDD to 250GB HDD, clone 1TB HDD to 500GB SSD, even clone 2TB HDD to 1TB SSD, etc. Because the only requirement is destination disk has enough space to save data on original disk.

How to clone 500GB HDD to 250GB SSD?

To clone a 500GB HDD to a 250 GB SSD, use the following steps:

1. Download, install and launch AOMEI Backupper. Select “Disk Clone” under “Clone” tab.

Note: This version only supports cloning system disk with the same partition tyle, such as, cloning GPT disk to GPT disk. If you want to clone GPT disk to MBR or migrate MBR disk to GPT, you could consider upgrading to AOMEI Backupper Professional.

2. Select the 500GB HDD as source disk, then click “Next”.

3. Select the 250GB SSD as destination disk, then click “Next”.

4. Check the option “SSD Alignment” to achieve the best performance of the SSD. Then click “Start Clone” to begin to clone hard drive to SSD.

If you just cloned system disk to SSD or new hard drive, you have two methods to ensure secure boot. The first method is to shut down your machine, disconnect current hard drive and keep only cloned disk connected in Windows 10 and then boot. The second one is to reboot your PC and enter into BIOS to change the boot priority to the cloned disk.

As long as the 250GB SSD have enough space to hold data on the 500GB HDD, you can use AOMEI Backupper to easily achieve to clone 500GB HDD to 250GB SSD. Even though the SSD is not big enough to save all data, you can use AOMEI Backupper Professional to clone only OS to SSD. Besides, cloning process will be running in the background so that it won’t interrupt your using of PC.
