   Yeah, current limit. My sample big drive (only an 18TB one), it   
   takes a while to spin up, and it also screws around a bit before   
   it becomes ready. It's not just loading the firmware off the   
   platter (which is the minimal requirement).   
      
   I notice they're allowing drives up to and including 14TB   
   to breathe air, and I bet one of those would be slow to start.   
      
   The platters are thinner, when there are a lot of platters   
   in there, so they don't have to be as heavy as the platters   
   in a four platter drive.
