If your laptop or PC is preinstalled with a small SSD, such as a 128G SSD, you might find that your computer is running increasingly slowly, especially when it is your Windows installation drive or full of data and programs. Buying a new computer will be costly, and you have to reinstall Windows OS and all necessary programs.

Fortunately, you have another way out: you can upgrade your old SSD to a larger one via cloning. This post from EaseUS will describe how to replace old SSD with new SSD without losing data or reinstalling Windows. Let's begin!

What You'll Use to Upgrade from Old SSD to New One

As mentioned above, cloning can help you change your SSD from an old one, but you have to make some preparations to help you achieve that. The following is what you will need to do to replace your old SSD with a new one.

🔣An SSD with the right interface, form factor, and storage space.

  • SSDs have different form factors (2.5-inch, M.2, U.2) and interfaces (SATA, NVMe). Since the NVMe SSD read speed is 6 times faster than SATA SSD, it is worth purchasing an M.2 PCIe or NVMe SSD, such as Samsung T9, Intel SSD 670p, Lexar NM790, Kingston KC3000, etc.
  • SSD's storage capacity ranges from 125GB to 4TB. Among them, the 250GB SSD is the most cost-effective if you want to use SSD only for OS installation. However, if you are a gamer, content creator, or professional, an SSD with a capacity of 500GB - 1TB is preferable.

To transfer an SSD to a new SSD, you need to connect the new SSD to your laptop/PC, so you should have a USB-to-SATA Cable, adapter, or hard drive enclosure.


It can help open the PC's or laptop's removable panel, remove the old SSD, and install a new SSD after cloning the old SSD to the new SSD on Windows 11/10/8/7.

🏆Best SSD cloning software

Since Windows has no preinstalled cloning settings, unlike backup, you need to turn to third-party disk cloning software for help, which is the core of replacing an old SSD with a new SSD.

Under such circumstances, EaseUS Disk Copy, a professional and versatile hard drive cloning software, comes to help. You need to download it to your laptop/PC and then use it to copy data from one hard drive to another.

How to Replace Old SSD with New One Without Data Loss

Replacing an old SSD with a new one includes 3 parts. You'd better follow the following instructions carefully in case something goes wrong. Let's come to the details.

Part 1. Initialize SSD

Generally speaking, for a new SSD, you need to initialize it. A new SSD/HDD must be initialized, or it might not work if you don't initialize it. The steps to initialize an SSD are the following:

If you use EaseUS Disk Copy, you can skip this part because it can recognize your SSD even if you do not initialize it. You can go to Part 2.

Step 1. Put the new SSD into a hard drive enclosure or connect it to a SATA-to-USB adapter, then connect the enclosure or adapter to your laptop/PC via a USB port.

Step 2. Go to This PC and check whether the new SSD appears as a new volume.

Step 3. Launch Disk Management tool. Typically, an Initialize Disk box will show up immediately. To initialize the new SSD, choose Disk 1 and tap OK.
