I just discovered today after reading an Associated Press article what measurement unit follows the now commonplace computer term gigabyte, which is defined as a staggering billion bytes.
The article spoke about a booming business for "electronic discovery" centres like Kroll Ontrack that keeps permanent digital files and other scraps of corporate intelligence that may be valuable in litigating lawsuits. These are not just Internet sites, mind, but also records kept in hard drives - "wedged between everything from personal e-mails to pornography", tech writer Brian Bergstein said.
The need to keep all the files in a database has ballooned the size of Kroll Ontrack's data-crunching centre in less than 18 months, from a half-petabyte of storage to two petabytes.
Wha? What's a petabyte? The Free Dictionary says: "A unit of computer memory or data storage capacity equal to 1,024 terabytes."
That's nice. Sounds like a jillion e-mails or Jpeg files. But how much more will that carry than, say, my soon-to-be-beefed-up 100Gb-capacity PowerBook G4?
And -first things first- what's a terabyte anyway? I had never heard of that before, although the past week had me asking coincidentally about the beyond of the beyond. It's a unit of information equal to a trillion (1,099,511,627,776) bytes or 1024 gigabytes. That's a lot.
So a petabyte -as if repeating it actually makes it easier for the mind to grasp- is 2 million gigabytes or one quadrillion bytes.
Consider that the Internet Archive, which aims to store almost every public Web page ever to appear, currently totals one petabyte. Or in familiar terms, 20,000 PowerBook G4 notebook computers valued at around US$2,000 each. (Okay, with the new Intel Core Duo Macs, which potentially have its hard drive capacity boosted from 10Gb to a theoretical 1 terabyte, maybe just a thousand of those. Still, it boggles the mind.) We are definitely moving on to bigger things.
Paging K-PAX and John Nash.
