Prepare for Absurdly Large Memory Cards
SanDisk just released its 64GB Ultra SDXC (extended capacity) memory card, the largest capacity for the Secure Digital format. It has a read speed of up to 15MB/second, stores up to eight hours of high-definition video, and costs $350. The new card uses the SD 3.0 specification, which allows capacities up to 2TB (2000GB).
It just so happens that today the CompactFlash Association also announced the CF5.0 specification, which allows memory cards up to 144PB (petabytes), or 150,994,944GB. Oh boy.
Sadly, the new Compact Flash specification only affords transfer speeds up to 32MB/s, meaning a full 144PB card would take about 153 years to transfer.

[...] The thought of a 64 gigabyte memory card is boggling. (Insert my story of buying 32 160 megabyte compact flash cards in 2001 at a cost of $399 – EACH – and a staffer losing one two weeks later.) [...]
Sweet I can capture moments, that the 2nd generation of my family can later see!! ;)
64GB at only 15mb/s not all that fast is it? Then again, what devices support SDXC or are SDHC devices compatible with the SDXC specs?
The performance doesn't make the size worthwhile and wont for a while.
I paid $400 for my first 1gb CF card about 7 years ago, while technology gets cheaper, the price point for new technology hasn't changed much!
Memory Cards of Unusual Size?
Basically all the new devices from panasonic, comes with the support of SDXC, or the new cameras from Canon…
Future Storage Size…
I would say this is pretty shocking in a way. Huge storage capacity but no way are they capable of being up to the technology that currently runs our computers. I think they should expand flash memory and learn how to minify it to take the place of SD …
