Why migrate Windows 10 to SSD?

To transfer Windows 10 to SSD usually means to move all content on Windows 10 OS drive and system-related partition to SSD, so that you can easily boot the computer from the destination SSD after migration. When it comes to why you need to move Windows 10 to SSD from a physical hard disk drive, there are two main reasons to be summarized.

In the first place, get better performance. There are no moving parts in a SSD, which makes it quieter and more resistant to damage. Furthermore, SSDs provide fast boot speed and shorter application load time. For users who need the efficiencies and convenience of an SSD, it is a good idea to migrate Windows 10 to solid-state drive. If you just want to extend storage space on the Windows 10 computer, SSD may not be the most economical solution.
What’s more, in your daily life you may have come across low disk space especially for system partition, which has bad effect on computer performance. When it affects your work and life constantly, you can transfer Windows 10 to a larger SSD to solve the trouble. Given that SSDs are more expensive than HDDs, it is also a wise choice to purchase an SSD with a smaller capacity, and then migrate Windows 10 to a smaller SSD and use SSD for OS and HDD for storage setup.

Clean install or migrate Windows 10 to SSD drive?

Whether you need to do fresh install is based on your willingness and software installed status on your current hard drive. To be specific, if you installed third-party applications separately from system drive, namely C drive, you can back up personal files in C drive and do a clean install on SSD. The installed applications on other drives will not be affected. If installed software is together with system programs, clean installing will take a lot longer since you have to reinstall all these programs as well afterwards.

In the meantime, all settings, configurations and stored data will be lost. If you would like to keep these data intact and save time, it is advised to migrate Windows OS drive to SSD.
