How to Replace Old SSD with New SSD on Windows Laptop/PC

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.

⚒️SSD connector

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.

🧰Screwdriver

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.

🏆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:

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.

Step 4. Right click on the unallocated space behind the new SSD and choose New Simple Volume.

Then, follow the on-screen guide to make a partition and give the new SSD a drive letter. Once you're done, the new SSD will show up on This PC as a new drive letter.

Part 2. Transfer Data from the Old SSD to New One

To change SSD to a larger/new one without data loss or OS reinstallation, you must use third-party disk cloning software, such as EaseUS Disk Copy, as Windows has no built-in cloning tools. Such a tool can let you clone a hard drive and replace a laptop's hard drive without losing data.

It is a practical disk cloning program for Windows computers and can help you clone an HDD/SSD from different manufacturers, unlike the Samsung Data Migration Tool. It lets you transfer your Windows from SSD to a new SSD and migrate data from one computer to another without trouble.

EaseUS disk clone software can suit you well if you want to replace your SSD with a new and it can also help you upgrade it to a larger disk. Ensure you download it to your computer and then use it to clone your hard drive.

Prior Notice:

• The "Sector by sector copy" asks the size of your destination disk to be at least equal to or larger than that of the source disk. Leave this feature unchecked if you wish to clone a larger hard disk to a smaller hard disk.
• All data on the destination disk will be completely erased, so take care.

Step 1. To start copying/cloning an entire disk to another, choose this disk as the source disk under "Disk Mode" and click "Next".

Step 2. Choose the other disk as the destination disk.

Step 3. Check the disk layout of the two disks. You can manage the disk layout of the destination disk by selecting "Autofit the disk", "Copy as the source" or "Edit disk layout". 

• "Autofit the disk" makes some changes by default on the destination disk layout so that it can work at its best status.
• "Copy as the source"does not change anything on destination disk and the layout is the same as source disk.
• "Edit disk layout" allows you to manually resize/move partition layout on this destination disk.

Tick the "Check the option if the target is SSD" option to put your SSD in its best performance.

A message now appears, warning you that data will be lost. Please confirm this message by clicking "OK" and then click "Next".

Step 4. Click "Proceed" to officially execute the task.
