Not necessarily just as fast. I remember reading about Facebook's "cold storage" mechanism a few years ago, where for rarely accessed media they would move it to a slower but cheaper data storage. The media is still available when someone tries to access it, but there might be additional latency compared to a non-cold stored item.
