Why need to transfer OS from SSD to new SSD?

Transfer OS from SSD to New SSD

Unlike hard disk drive, SSD (Solid State Drive) has no moving parts and stores information in the microchip, which makes it much faster and more durable. Besides, SSD works without noise allowing to read and write all day long, and the data storage integrity will be maintained for a long time. Thus, many users want to use SSD for OS and HDD for storage.

However, the disk space is limited and will be full, thus you may still need to migrate OS to a new SSD for large capacity. Or the SSD disk performance slows down, or it's falling with the smart error or has other issues, you need to replace it with a new one, for example, transfer Windows 10 from one SSD to another

Among SSD disks, the NVMe SSD that operates across the PCle bus has a fast reading and writing speed. You can search best NVMe SSD online and get one if you have enough budget. The NVMe SSD with M.2 PCI-E x4 slot is the best option.

Best OS migration software for Windows 7/8/10/11🏆

To migrate OS from SSD to new SSD of all brands (Samsung, WD, Toshiba, Crucial, etc) and different interfaces (SATA or NVMe), cloning is the simplest way as long as you find a reliable OS migration software. Considering secure boot issue, AOMEI Backupper Professional is a great choice.

It provides you with 2 ways for this cloning task. You can choose System Clone or Disk Clone feature, depending on the items you want to clone and disk space of target disk. 

✦ System Clone: It clones only operating system, system settings, installed apps and personal files on the system partition(s). Support cloning system between two MBR or GPT disks, or cloning MBR disk to GPT and vice versa.
✦ Disk Clone: It clones the entire system disk, not only system partition(s), but also other data partitions. Considering the amount of data, it will require more disk space.

By default, this software clones only used sectors of a partition or disk, thus you can easily migrate OS to smaller SSD. Also, if the target disk is large, you can choose to clone all sectors of system partition or disk by "Sector by Sector Clone".

How to transfer OS from SSD to SSD step by step

Before moving OS to SSD:

  • Insert your new SSD into the computer and make sure it can be detected. For a laptop, you need an external enclosure or adapter to connect SSD to your laptop.
