[citation][nom]tayb[/nom]I don't get it. I can buy a 2TB HDD for $180 from newegg. I could have about 45 TB of hard drive space to own instead of leasing 16TB from google for a year... And I would get to store things besides photos...Why would I do this? At all?[/citation]
Google will not store that 16TB on a single computer, as that would mean there's a single point of failure. That 16TB probably involves at least 50TB of data on about 5-6 servers placed in different parts of the datacenters they have so that if there's a power failure on a server rack and the hard drives fail, data can be recovered from a drives in a server on another rack.
As other people said, it would cost you more than the price of the drives: bandwidth, case (maybe you want to place it on a rack in a basement), motherboards, processor, memory, hardware raid controller (and you want raid 5 at least), UPS or at least surge protection...
