Compact Flash 5.0 Specification Raises Capacity to an Incredible 144 Petabytes
The Compact Flash Organization (site) released their new 5.0 specification earlier today, and it completely blew past previous storage limits. The prior specification for Compact Flash maxed out at 137GB. Now the new spec supports up to 144 petabytes (PB).
A petabyte is a huge number — most people haven’t encountered it before. To put it in perspective, a petabyte is roughly 150 million gigabytes. Imagine looking around your home at a Blu-ray collection: six million Blu-ray titles could fit on a single Compact Flash 5.0 card.
I guess that means no more RAID boxes, right? After all, what’s better than solid-state memory with storage capacity the size of Texas?
We started doing the math on how long it would take a CF Duplicator to copy a Compact Flash 5.0 card, laughed, and gave up. There simply isn’t technology available today for bulk data loading of that magnitude — let alone a legitimate use case for storing that much information on one card.
While there isn’t a practical use for the full 5.0 spec yet, there are other improvements to get excited about. According to the CFA, Revision 5.0 brings:
- An optional quality-of-service framework to guarantee performance levels and prevent dropped frames.
- More efficient cleanup of unused space.
- A new electrical design that better complies with ATA standards.
There’s no mention yet of when Compact Flash 5.0 cards will ship, but if you’re interested you can read more about the new spec here [PDF], or purchase the full official specification.
