Is there such thing as a Perabyte?

Question

I recently saw a marketing video that cited the "Perabyte" as a unit of disk storage measure. I emailed a representative responsible for the video and got a response that "1 Perabyte (PB) = 1024 Terabytes (TB)."

A quick google search seems to indicate that a Petabyte is defined as 1000 TB.

Is a Perabyte a real thing, and is it 1024 (vs 1000) TB?

Edit: This thread has answered my question, despite the votes to close. No one has heard of a "Perabyte" except as a misspelling of "Petabyte." Thanks.

Edit (2): Petabytes have been tagged real by "BRIGHT SIDE"

I'm voting to close this question as off-topic because this is asking for a general computer terminology definition. — Daniel A. White, Sep 22 '16 at 18:18
Given that no search results clarify "Perabyte" vs "Petabyte" yet the misspelling is common enough to generate plenty of search results (and resultant confusion), this question seems to me to be worthwhile. — Nate Vaughan, Sep 22 '16 at 18:57

A perabyte doesn't exist, but a petabyte is a real thing. It is

2^50 bytes; 1024 terabytes, or a million gigabytes.

your answer was unrelated to OP's question – DhruvPathak Sep 22 '16 at 18:14
Why @DhruvPathak? It answers the exact question, no? – baao Sep 22 '16 at 18:14
I guess you mistyped "Perabyte" as "Petabyte". Can you update your answer to correctness ? I will remove the downvote then. – DhruvPathak Sep 22 '16 at 18:15

It seems likely that your perabyte was the result of a typo, seeing as 'r' and 't' are close on the keyboard.

The 1024 versus 1000 question most likely arises from which base you are using. 1024 is base 2, 1000 is base 10.

A petabyte is 1000⁵, or 1000 terabytes.
A pebibyte is 2⁵⁰, or 1024 tebibytes.

A perabyte is not a thing.
