The largest data warehouse resides at the IBM Technology Campus in Dublin, Ireland and contains 3 petabyte (3,000 terabytes) of raw data. The software is IBM - DB2 Information Management and the official date of the record is January 18, 2012.
According to wikipedia:
A petabyte (derived from the SI prefix peta- ) is a unit of information equal to one quadrillion (short scale) bytes, or 1 billiard (long scale) bytes. The unit symbol for the petabyte is PB. The prefix peta (P) indicates the fifth power to 1000:
- 1 PB = 1000000000000000B = 10005 B = 1015 B = 1 million gigabytes = 1 thousand terabytes
According to Gizmodo:
How Large Is a Petabyte?
13.3 years of HDTV content. That's approximately 58,292 movies, which means an equal number of large pizzas. So one petabyte equals 52 tonnes of pepperoni pizza. Yes, my head has assploded. For other equivalents, click and zoom in.
How big are 20 million four-drawer cabinets? As big as the Sears Tower? I have a hard time visualizing that. Strangely enough, I don't have any problem visualizing 52 tonnes of pepperoni pizza.
With the amount of data that is being collected and analyzed these days, I expect this record to be broken sooner than imaginable!
