Why migrate Windows 10 to SSD?

To migrate 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 use these file to boot from target SSD. When it comes to why you need to copy Windows 10 to SSD, there are two main reasons to be summarized.

In the first place, get better performance. There are no moving parts in SSD, which makes SSD quieter and has less possibility to get damaged in. Further, SSDs provide fast boot time and shorter application load time. For user who needs the efficiencies and convenience of an SSD, it is a good idea to migrate Windows 10 to new drive. If you just want to boost the amount of storage on the Windows 10 computer, SSD may not be the most economical solution for you.

Whether you need to do fresh install is based on your willingness and software installed statue on your hard drive. To be specific, if installed third-party applications separately from system drive, namely C drive, you can backup 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 together with system programs, clean install takes a lot longer to reinstall all these programs.
