petabyte

(unit)

2^50 = 1,125,899,906,842,624 bytes = 1024 terabytes or roughly 10^15 bytes. 1024 petabytes is one exabyte.

Google is estimated to store about 200 petabytes of data in about 25 data centers around the world.

petabyte

One quadrillion bytes. Also PB, Pbyte and P-byte. In 2012, Facebook indicated that it stored 100 petabytes of member data. See Petabyte Age, peta, brontobyte, Hadoop, binary values, petabit and space/time.

Hard to Imagine

A large datacenter holds petabytes of data in all of its drives combined. However, we have a long way to go for a single storage drive to hold just one petabyte.
