Superfetch: A concise answer

[gurusan]

What does it do?
How is it implemented?
Does it take any sort of time to be overwritten when memory is requested?
Does it ever write to the hard drive?
What makes anyone think disabling it will make it faster, and why are they wrong?

So I don't have a total understanding of this but have come across people disabling it by dozens.

Would like just a clear explanation of it if anyone has the time, thanks.
