Why need to perform Samsung Data Migration OS only?

Samsung Data Migration (SDM) is a data migration tool that comes with Samsung SSDs like Samsung 850 EVO. It helps users migrate operating system and data from existing storage device to the new Samsung SSD without reinstalling. Then, why would someone want to clone OS only?

There are two common factors account for the phenomenon. One is the purchased Samsung SSD is not large enough to accommodate all data on the old hard drive. Surely, shrinking partition, deleting files and uninstalling programs are helpful in cloning larger drive to smaller drive. However, move OS only is more directly.

The other is the older hard drive is good enough to be a secondary storage. The SSD for OS & HDD for storage arrangement usually happens in desktops or laptops that have two available disk bays. The combination makes full use of HDD’s and SSD’s advantages. Performance improved and storage saved, why not?
