By making a string = "" you are discarding any value within the string, assigning a value to that string (even though that value is a null), and causing it to look for exceptions.

String.Empty does not look for exceptions and merely discards any extant value, it does not assign a value thereafter.

It is much quicker.

Then you have not read the articles properly. Most of the articles describe the reason as well.

A simple Google search will also tell you the answer.
