Although virtual memory is beneficial at times, why can it also be detrimental?

It converts data from nonvolatile to volatile storage devices.
It relies on data that is placed on the hard drive, which slows down the computer.
It increases the likelihood that data can become corrupted.
It requires a larger amount of bus width, which slows down the computer.
