Re:Seagate hits 1 terabit per square inch, 60TB hard drives ...

Random access performance will be an issue, unless they work some magic on that, too. Same for bus-speeds.
Today you can fit about 96T into 4U if you squeeze a little.
That's 48 spindles then, sharing the load.
With 60T drives that turns into 2.8P on the same 48 spindles.
At today's maximum SAS bus-speeds (roughly 10 GBit/s) it would take 33 days just to write such an array full (assuming all components can sustain that throughput).
And let's not get started on IOPS...
Anyway, it will be a while before 60T drives hit the shelves. Until then at least the bus-speed issues will probably be sorted out.
