Why do you need disk cloning software for Windows 10?

Disk cloning allows you to make an exact copy of your entire disk, including the operating system and all your files. There are several reasons why you might want to clone your disk in Windows 10:

Upgrade disk without reinstallation
Bothered by slow boot speed or low disk space, you may want to upgrade a traditional HDD (hard disk drive) to a faster SSD (solid-state drive) or replace a small SSD with a larger one. To avoid the reinstallation of OS and apps, it’s wise to clone the hard drive.

◥ Clone disk for backup
No hard drive is immune to damage or virus infections. By cloning your disk, you create a duplicate of all your data.  By having a cloned disk ready, you can quickly replace the failed drive and resume your operations without losing valuable data.

◥ Time-saving in disaster recovery situations
In the event of a major system failure or natural disaster, time is of the essence in recovering your operations. Cloned disks enable faster recovery times as you can quickly restore your system to a functional state. This saves valuable time that would otherwise be spent reinstalling the operating system, and applications, and restoring data from separate backups.
