Need to clone 500 GB HDD to 256 GB SSD

“To have better experience in booting the operating system or loading programs, I have purchased a 256 GB Toshiba Q Series Solid State Drive and I have a 500 GB HDD with only 129 GB used. Now, I want to replace my HDD with the SSD.

But I’m really unwilling to make a fresh installation of Windows and other applications on SSD. Thus, I want to clone the old HDD to the new Toshiba SSD. I know that it is available to clone HDD to smaller SSD. But what should I do?

HDD  VS SSD

Great cloning software: Clone HDD to SSD easily and safely

It is common to choose to purchase an SSD whose capacity is smaller than HDD's due to SSD’s price. You can easily clone 500 GB HDD to 256/120 GB SSD as long as the used space of your source hard drive is not beyond the capacity of the target SSD with drive cloning software, like AOMEI Partition Assistant Professional.

It can clone only used space of source disk, enabling you to clone larger hard drive to smaller drive, covering 500 GB HDD to 120/256 GB SSD, 2 TB HDD to 500 GB SSD etc. without data loss.
And it can make SSD partition alignment to improve SSD’s performance while copying HDD to SSD.
It works under Windows 11, 10, 8, 7, XP, and Vista. To clone HDD to SSD in Windows Server 2022/2019/2016/2012/2008, please use AOMEI Partition Assistant Server.

You need to connect the SSD to your PC and make sure that it can be detected by your OS. If what you own is a laptop, you might need a USB-to-SATA cable.
