User case: how to transfer SSD to SSD

How to move everything from one SSD to another?

Recently, I got a new computer but immediately filled up the SSD with files and programs. Now, I'm dangerously low on disk space. Therefore, I intend to replace the current SSD with a larger one. But I just want to keep the files, games and the OS on the SSD. So, I'm wondering if I can move all the things including files, programs, and OS from one SSD to another?

Why move files and OS from one SSD to another?

SSDs come with better read/write and startup speed than HDDs, as well as higher pricing for equivalent capacity. Many users have purchased smaller SSDs (125/250/500 GB) for budgetary reasons. As a result, the cumulative files and programs can easily fill up the disk, resulting in insufficient storage space and slow computer operation.

But nowadays, SSDs have become increasingly popular and affordable with the progress of technology. In addition to capacity considerations, many users would also like to replace their SSD with a more advanced model for better experience, such as cloning SATA SSD to NVMe.

Sooner or later, it will become a necessity to switch to a new drive with larger capacity and better performance. But in many cases you may don't want to abandon your data on old SSD, or spend much time reinstalling Windows and apps, you may need to transfer files and OS from SSD to a larger SSD directly.

Two ways will be described in this page:

How to transfer data from one SSD to another effortlessly

It is easy for you to transfer a small number of data files by the copy and paste method. But when it comes to large groups of files, various programs, and even the complex operating system, things won't be that easy.

If you still take the manual copy and paste way, your computer may fail to boot due to some hidden files missing. Therefore, you need a professional clone software like AOMEI Backupper Professional to help you move a large number of files from one drive to another efficiently, and copy programs, games and OS correctly.

AOMEI Backupper is a reliable SSD disk migration software for Windows 11/10/8/7/Vista/XP. It enables you to transfer all data from one SSD to another easily and securely.

Disk Clone - All files on the source drive including the programs, games and operating system will be copied to the target drive without reinstallation.

Intelligent Clone - It copies only used sectors by default, allowing you to transfer data to a smaller SSD. If you are moving files to a larger SSD, you can use sector-by-sector clone to ensure the integrity of cloned data.

SSD Alignment -  Align partitions of the target SSD with one click to improve the reading & writing speed and prolong its life span.

Secure Boot - After migration, you can boot from the cloned SSD successfully.

Transfer SSD to another SSD step by step

Preparations before moving data:

  • Connect the target SSD to your computer and make sure it is detected.

  • Download AOMEI Backupper. Install and launch it to get started.

1. Select "Disk Clone" under the "Clone" tab.

Disk Clone

◑ The Professional edition supports cloning both data disks and systems disks from MBR to MBR/MBR to GPT, or GPT to MBR/GPT to GPT. If you only want to clone data disks, you can pick the complete free Standard edition.
◑To move my OS from one SSD to another, it's suggested to try "System Clone" feature.

2. Select the original SSD that you want to clone as the source disk, and then click on "Next".

Select Disk

3. Choose your new SSD as the destination disk, and then click on "Next".

Select Destination Disk

4. Tick “SSD Alignment” to accelerate the read and write speed of the SSD disk. Then, click "Start Clone" to begin cloning one SSD to another. Optionally, click "Sector By Sector Clone" to ensure data integrity.

Start Clone

Tips on disk space management and disk partition styles:

You can use the "Edit Partitions" feature to resize partitions with different options and convert the disk type.

  • Copy without resizing partitions: It's the default option and will not resize the partition size.
  • Add unused space to all partitions: It will add unallocated space to all partitions automatically.
  • Manually adjust partition size: Extend unallocated space manually by selecting a partition and drag the unallocated space to left or right side.
  • Convert the destination disk from MBR to GPT: Convert the partition style of the target disk to make it the same as the source disk. You can either convert from MBR to GPT or GPT to MBR.

Copy Without Resizing

Choose cloning mode accordingly:

While transferring data, this software runs in an intelligent-sector mode by default. It means only used sectors will be copied, those unused and logically bad sectors will be skipped. If your target drive is smaller than the source drive, then just keep the default settings.

However, if your target drive is larger than or equal to the source drive, you can tick the sector-by-sector clone option to make sure copying every sectors no matter used or not. This is especially useful when you want to clone a hidden recovery partition and ensure it still works on the target new drive.
