  •  Overall internet traffic is 1000 PB/day. (2+ / 0-)

    How can they store all of it if they only store 20 TB/day or so? It's still unclear what do they actually store.

    •  It says some sites can only store 20TB per day and (0+ / 0-)

      if it is a small site then that might be reasonable.

      You have watched Faux News, now lose 2d10 SAN.

      •  Possibly those are mobile capture units. (1+ / 0-)

        E.g. vans that just capture WiFi. The bandwidth would be so small that 20T would make sense.

        Or they might be sites in extremely rural areas.

        Regardless, it's the big sites that matter, not the small ones. This whole "some sites are as small as" schtick is a blatant attempt at misdirection by the NSA. And quite a few people here have fallen for it.

      •  But the way it was written is that some sites (0+ / 0-)

        have so much traffic (over 20 TB/day) that their data can't be stored for very long. It was clear that these were the biggest sites.

        •  Not necessairly. Suppose the "site" is just a (1+ / 0-)

          large wifi/cellular* sniffing van.  In a crowded enough area you could get more than 20TB of wifi and cellular traffic per day.

          *For capturing cellular voice, SMS/MMS, and data it would act as a fake cell tower.  In fact, a regular cell range extender which anyone can buy online can be modified to act as a cell sniffer and capture everything (voice, data, text messages).

          "This snooping hack-in-a-backpack could become a hot Summer accessory, since Reuters reported that 'researchers at iSec hacked into a Verizon network extender, which anyone can buy online, and turned it into a cell phone tower (video interview) small enough to fit inside a backpack capable of capturing and intercepting all calls, text messages and data sent by mobile devices within range.'"

          •  Could be. That's not how I understood it but (0+ / 0-)

            I'm not a mind reader. Still, most traffic is not mobile and a sniffing van will catch only a very small percentage of mobile traffic.
