Why need to clone hard drive?

Usually, you may need to clone hard drive for following reasons:

1. Get better performance. Compared with HDD, SSD is more durable, faster, lighter, quieter, cooler and it consumes less power. So, you can clone hard drive to SSD for a better performance.

2. Need larger capacity. As time goes by, you will have more and more personal data and programs on your hard drive until it is almost full. Therefore, you need a new drive with a larger capacity to replace the old one. You can clone the original hard drive to the new one.

3. Migrate OS. If you want to migrate OS without reinstalling programs and settings, you can clone the hard drive to have the same operating system configuration on another machine.

Does cloning a drive copy the OS?

In fact, hard drive cloning is a process of migrating all data. In this process, the entire contents of one hard drive including the operation system will be cloned to another drive. Therefore, if your OS is located in this hard drive, the OS will be copied. After cloning, the same operating system configuration can be used on the new drive.
