Cables and switching infrastructure weight a lot. mSata SSDs weight as less as 7g. So the total weight of the SSDs is 1778g. I guess you can save more then 2kgs

Cables and switching infrastructure weight a lot. mSata SSDs weight as less as 7g. So the total weight of the SSDs is 1778g. I guess you can save more then 2kgs when you buy lower capacity switches and share some cables. I also think that they might have needed another central server for serving all the clients.
