"1PB in a rack"? You can apparently already buy 2.5PB in a single 4U server: https://www.techradar.com/pro/seagate-has-launched-a-massive-29tb-hard-disk-drive-

  sorry I should have added a caveat of 1pb _at decent performance_ That seagate array will be fine for streaming (so long as you spread the data properly) as soon as you start mixing read/write loads on that, it'll start to chug. You can expect 70-150iops out of each drive, and thats a 60 drive array (from guess, you can get 72 drives in a 4u, but they are less maintainable, well used to be, thing might have improved recently) When I was using luster with ultra scisi (yes, that long ago) we had good 10-20 racks to get to 100tb, that could sustain 1gigabyte a second.

    Agreed, it depends on the use case. For some "more storage" is all that matters, for others you don't want to be bottlenecked on getting it into / out of the machine or through processing.
