p.1 #1 · 2TB SD Cards

The SD Association announced the followup to the SDHC card, the SDXC with a capacity of 2000GB. It will certainly be nice to expand the next generation of video capture in DSLRs though it begs the question of what is the next generation of backup??

It won't help you have longer video as long as they still use the FAT 32 file system which limits individual file size at 4GB.

it will be using the exFAT file system which allows the same file sizes as NTFS

damn.... that's insane....

how stable do you think it will be in terms of long term stabilisty?

if they don't cost 2000 bux each, they might make a good alternative to external disk drives...

Well in theory its supposed to be 5 years at a minimum however exposure to static, radiation or magnetic energy may cause your mileage to vary. I suspect some engineering group will design a system where different flash banks will offer a parity design for backup purposes.

In regards to price the target is to be able to hit a manufacturing cost of 11 cents per GB within several years.

2TB, I would only have to take the card out of the camera every 3 years or so.

2 TB is the max storage capacity available in theroy.
In practice it will never happen with the current SD format we know.
This is more interesting on the data transfer speed than on the storage space capacity. we all know that it is a much better idea to have 4x2 GB SD cards than a single 8 GB SD for obvious reason of reliability and lifetime of such flash memory, as well as budgetwise.

I think the main focus is or should be the speed of the card, the speed needs to go relative with the amount of data these cameras are pumping out. When you're firing off 10-12 megabyte photographs 4-6x a second, you need a card that can keep up and try to write that data quick before filling the buffer. Then again, when you have a fast card, that means your card is gonna fill up faster, so the need for a bigger card arrives. It's just a never ending hill.

But anyways, that's pretty cool.

this argument always makes me laugh, i remember when folk were scared of a 1GB card and said 2 x 512MB cards were better and then it was the 2GB card and the 1GB x 2 fellas feeling good about themselves.

In all the terabytes of images i have shot now I have had 3 bad card writes and none of them mattered in the end , so i don't worry about it at all ever now

twice as many cards means roughly twice as high likelihood of failures. the greatest risk to cards is not internal failure because of manufacturing but the insertion process.

Now all we need is a camera with a sensor that could fill it up in 36exp. How many terapixel would that sensor have? Or would it be gigapixel?

No, but with 30MB RAW files, my Fujis could certainly need one
