Question.

Where does facebook store all of it's data? According to Facebook themself - the social networking website generates over 500 Terabytes of data every day. That is every 24 hours.

The reason I ask this is because how do they manage this. Surely they must be having trucks of hard drives coming in every day - or am I looking at it wrong? At this rate of manufacturing devices for data storage (utilizing silicon) aren't we going to run out of sand and have a bunch of hard drives lying around our beaches? lol

They use things like Data Warehouses and services provided by Akamai Technologies. So a lot of their storage isn't on-site, it'll be distributed around the world, as will the trucks bringing HDDs in ;)

the social networking website generates over 500 Terabytes of data every day.

Does this mean that they collect and store that amount, or that the pages they generate and send out to clients total 500TB?

It means all the core data coming in from users. Photos, Text, Likes, Comments, Videos etc

In that case, it is a lot of data to store! Just a fun, half-relevant fact: they also use BitTorrent to move some of their data between servers

Facebook data storage is so funny.
