Why you need to split local disk in Windows 10/8/7?

Originally, when you buy a new computer, there is only one partition on your local disk, stored with the system files. And you may store many other data to your local disk, and the data will be saved on the unique partition. When you need to use one file, you should find it with a mass of data. What’s the most, it is not safe. The system may crashed because of so many factors. Once it failed, all your data will be erased.

To solve those kind of questions, the most effective way is to repartition disk, so that you can get more partitions to store different kind of data. For this, you can split local disk first.
