CompactFlash 5.0 spec brings 144PB capacity limit

By on February 22, 2010, 6:59 PM
The CompactFlash Association has announced a new specification that brings 48-bit addressing, which increases the current capacity limitation of 137GB to 144PB -- as in petabyte. For the mathematically impaired, that breaks down to around 150 million gigabytes, or six million single layer Blu-ray discs. It also supports up to 32MB per transfer action, compared to 128KB today.

Obviously current data densities can't reach the ceiling of CompactFlash 5.0, but there are other new features to get excited about. The CFA says Revision 5.0 brings an optional quality of service framework that guarantees a certain level of performance and prevents dropping frames, more efficient cleanup of unused space, a new electrical design that better complies with ATA standards, and updated ATA references to ATA-6 and ATA-8/ACS-2.

There's no mention of when CompactFlash 5.0 cards will ship, but interested parties can learn more about the revision here (PDF), or download the specification for $100.

That's insane! lol, I wonder how many full res 21mp photos I could fit on there? Just think of it... you would never need to erase your memory card (though it would be a pain in the ass to search for pics on it)

I didn't even know a petabyte existed! It would take nearly 3 years to fill it using a CF duplicator

At long last, a viable substitute for the human brain's memory capacity.

You of course meant to say, "Skynet Clause"..

"Skynet Clause bees up in Yo Greel" That works.

OK, some fine tuning.

"Skynew Claws, nose bees up in Yo a**"!
