I know people have thrown around the idea of the Utah facility being yottabyte class storage, but that's about the technology they're using (such as ZFS as you mentioned), not what they actually have. A yottabyte is a couple hundred times larger than the entire estimated size of the internet. There is no present technology that could pack that much data into their datacenter and still access it. A solid block of micro-SD cards with the cases removed wouldn't fit. * -- * PV Something like badgers, something like lizards, and something like corkscrews.

Oops, you're right. Thank you for the catch -- a second set of eyes is always helpful! :-) Using this URL as a reference and doubly-checked elsewhere: http://highscalability.com/blog/2012/9/11/how-big-is-a-petabyte-exabyte-zettabyte-or-a-yottabyte.html I created the following table (with a printed copy on the wall beside my desk) that others may find useful, too. A fixed-width font should be used to view or print this: Byte (8 bits): 1 byte Kilobyte: 1,000 bytes Megabyte: 1,000,000 bytes Gigabyte: 1,000,000,000 bytes Terabyte: 1,000,000,000,000 bytes Petabyte: 1,000,000,000,000,000 bytes Exabyte: 1,000,000,000,000,000,000 bytes Zettabyte: 1,000,000,000,000,000,000,000 bytes Yottabyte: 1,000,000,000,000,000,000,000,000 bytes Xenottabyte: 1,000,000,000,000,000,000,000,000,000 bytes Shilentnobyte: 1,000,000,000,000,000,000,000,000,000,000 bytes Domegemegrottebyte: 1,000,000,000,000,000,000,000,000,000,000,000 bytes > I know people have thrown around the idea of the Utah facility being > yottabyte class storage, but that's about the technology they're using > (such as ZFS as you mentioned), not what they actually have.

For net service it's not ever 3% of what they charge you. So they could essentially charge you $10 a month for good net service and still make a profit. And I'm hoping Google eventually wires up the entire U.S. It would put a shot across the bow of the likes of Verizon, at&t, Cox, Comcast et al. I mean, you've got options with Google like pay a $300 construction charge and get 3mbps/1mpbs service in perpetuity. Or pay for higher bandwidth. But it would FORCE in my case Verizon and Cox to play nicely.
