Disk partitioning is one of those things where you find many conflicting opinions. Some will swear that proper partitioning aids performance, makes backing up easier and is just generally “better”.
Others just opt to let Windows sort it all out, believing that improper partitioning might well prevent the file system – already optimized for both safety and performance – from operating in a maximally optimal way.
The truth is somewhere in between, I’m certain.
While I tend to fall into the latter camp, I’ll look at some of the pros and cons to partitioning your hard drive, and make a recommendation if after all is said and done you’re still not sure.
