I wonder why they are submerging these instead of just making them a floating barge.
I can't imagine submersion is significantly better for cooling, the energy density very likely already requires a circulating water system, and the added issues dealing with the pressure at depth seem risky.
Possibly there is a benefit not related to cooling. Perhaps weather/waves? Things are probably alot calmer 30ft below the surface. The tossing and turning on the surface may place additional streses on things like HDD spidles.

- sathackr 8y agoSpinning hard drives have a decent gryoscopic effect. Hold one while it's powered up and try rotating it in a manner that would change the plane of the platters and you will feel the resistance. Each time you do that, it puts a slight load on the spindle bearings. Do it repeatedly on a varying 5-30 second cycle and you'll simulate what a harddrive on a boat or barge in the open water would experience. I can imagine that would create additional wear and tear and contribute to an increased failure rate.
