Tape has long been the media of choice for very cold workloads and tape remains an excellent choice at scale. What\u2019s unfortunate, is that the scale point where tape starts to win has been going up over the years. High-scale tape robots are incredibly large and expensive. The good news is that very high-scale storage customers like <\/font>Large Hadron Collider (LHC)<\/font><\/a> are very well served by tape. But, over the years, the volume economics of tape have been moving up scale and fewer and fewer customers are cost effectively served by tape.<\/font> <\/p>\n
