Array or hash in Ruby

Could anyone explain what is faster for reading, writing in Ruby: an Array or a Hash? And what are the usecases for Array and Hash?

If you need to store only some unique unordered values, please consider using Set.new. It's convenient hash based class with writing and reading in constant time.
