Currently petabyte responsibilities are mostly restricted to the IT departments of research organizations -- telescopes, molecular genetics labs, particle accelerators.
A petabyte of data is so big, and the quality of the information it contains is so low, that it is bound to contain and create inconsistent information, which means that any petabyte-level system has to contain ways of detecting and resolving data conflicts.

 Definition of Petabyte
A petabyte is 2 to the 50th power, or 1,125,899,906,842,624 bytes.
A petabyte is 1,024 terabytes and precedes the exabyte unit of measurement.
Since even the largest hard drives are measured in terabytes, petabytes are only used to measure the storage space of multiple hard drives or other collections of data.

The fact that a petabyte drive is real and will be here in seven years is absolutely amazing and will transform much of the way computers are used today.
Thus the petabyte disk will hold some 500,000 hours worth of movies; if you want to watch them all day and all night without a break for popcorn, they will actually fill up your petabyte drive if you have a lifetime of video on it as it will give you 57 years of video.
However, a second petabyte derive could record every moment of life, in high-quality video, of the oldest person on earth.

To realize this vision, significant advancement in storage and storage management must be achieved to dramatically reduce the cost of these storage systems, which would otherwise fall in the range of $50 to $100 million using today's enterprise-class storage devices.
The Real-Time Petabyte Challenge is currently using data from three separate Cornell projects funded by a $1.8 million grant from the National Science Foundation and Cornell's Computer and Information Science and Engineering directorate.
By the third year of the grant, the system is expected to exceed one petabyte of data.

 What is a Petabyte?
In the world of ever-growing data capacity, a petabyte represents the frontier just ahead of the terabyte, which itself runs just ahead of the gigabyte.
In other words, 1,024 gigabytes is one terabyte, and 1,024 terabytes is one petabyte.
Beyond the petabyte are the exabyte, zettabyte and yottabyte.

 Tower Of Power - News by InformationWeek
At today's prices, the cost of buying a petabyte database and its attendant hardware, software, and personnel is probably too big for a private-sector company: $500 million to $750 million, estimates Richard Winter, an industry analyst who specializes in large databases.
That's why IT managers who can imagine a petabyte in their future should be running their database today on a highly scalable system, including massively parallel processor hardware such as NCR's Worldmark or IBM's eServer xSeries to which processor nodes can be added as the system expands.
A database with a petabyte of raw data is further off--about five years away, says Tim Donar, a senior system architect at Acxiom Corp., which builds and operates data warehouses for large clients.
