Honestly, cloning is the easiest way to clone smaller SSD to larger SSD of all sizes, not only clone128GB SSD to 256SSD, but also clone 256GB SSD to 500 SSD, clone 256GB SSD to 1TB SSD, clone 500GB SSD to 1TB SSD, and more. But there are things you need to pay more attention to:

  • A reliable and powerful SSD cloning software.
  • Way to connect the new SSD for cloning.
  • Safe boot.

Don't worry about them much and I'll introduce you to these things below. Please continue to read this article and clone 128GB SSD to 256 SSD with a safe boot.

Why Clone 128GB SSD to 256GB SSD?

SSD as a high-speed hard drive is used to install OS to gain a faster speed and shorter boot time. And many manufacturers do so, to save cost, the computer usually comes with a 128GB SSD drive, but as time goes by, you will find that it can't meet your demands anymore due to the lower free space, slow response, application corruption, and other problems.

So it is an urgent task at this point to clone SSD to larger SSD, from 128GB to 256 GB, 500 GB, 1 TB SSD, etc. Here we summarize some common reasons:

✍ Keep your computer in high performance. Except for SSD performance itself, you still need to be sure there is enough space on it, then your computer can run very smoothly, just like getting a new one. 

✍ Avoid reinstalling Windows and applications. The cloning method will transfer everything on the 128GB SSD to a new SSD including the OS, installed programs, drivers, settings, personal data, etc. So you don't need to do a reinstallation and have more time to do some valuable things. 

✍ Replace outdated SSD disk. The speed of hardware updates like SSD is so rapid nowadays. So if your computer's built-in SSD drive is coming to an end, you may want to replace it with a new one.
