'[EE]::Compact Flash not quite dead yet'
CF / Compact Flash strikes back.
Just when the SD wannabee thought it was winning.
500 MB/s (using PCI Express!) (B, not b, they say).
Addressing to 2 TB
500 MB/s sounds awesomely fast.
They you look at how long it would take to download 2 TB.
2000/0.5 = 4000 seconds = 67 minutes!
However, a nice little 64 GB card would download in a mere 2 minutes 10s or so.
CompactFlash is not dead and SanDisk, Sony and Nikon want to make it better
NOVEMBER 30, 2010
Today SanDisk, Sony and Nikon “announced the joint development of a
set of specifications that address the future requirements of
professional photography and video markets.” Those specifications were
submitted to the CompactFlash Association and the goal is to
standardize the CompactFlash format. The proposed specifications
target “Professional photography and High Definition (HD) video
Data transfer rates of up to 500 megabytes per second (using the PCI
Extend the theoretical maximum capacities beyond 2 terabytes
Low power consumption achieved by power scaling system to extend battery life
Improved physical ruggedness and reliability
It seems that they also proposed a physical improvement to the
existing CF cards: “similar in size to a CompactFlash® card, the new
specifications’ access control function and highly durable form factor
produce a combination of physical ruggedness and reliability that is
indispensable for professional usage models”

Yup, saw the article, and to be frank, it's completely worthless.
Why? 2TB limit? What are they thinking? Flash capacities are already at
the 128GB range, 2TB is only a few years away, and yet they're coming up
with a standard that will limit capacity in just a couple years?
