The SD Association has unveiled a new generation of SD cards, dubbed SDXC. These “eXtended Capacity” cards are likely to provide 64 GB of storage at first and will eventually max out at a whopping 2 TB.
Read/write speeds will start at 104 MB per second, but the SD Association plans to push that speed to 300 MB per second over time.
Mobile phones are seen as the main benefactor in this development. One could imagine fancier video games and higher quality music and video if this new generation becomes the standard.
“SDXC allows users to enjoy more from their mobile phones. Larger capacity and faster transfer speeds allow for expanded entertainment and data storage,” James Taylor, President of the SD Association, said in a press release. “At its maximum 2TB capacity, an SDXC memory card will store an estimated 100 HD movies, 480 hours of HD recording or 136,000 fine-mode photos.”
Obviously, camcorders and cameras will benefit as well. Shigeto Kanda, a general manager at Canon, suggests in the press release that SDXC can store more than 4,000 RAW images.
There’s no mention of replacing optical media in this press release, but it’s a point that will become hard to ignore if these cards become cheaper. At least for storage purposes, SD could beat out discs in the long run.
As for replacing entertainment media, with all the standalone Blu-Ray players, DVD drives and car CD players, that’s going to be slow to budge. In any case, it’s not something that the SD Association is touting right now.

Also, just think about taking a bunch of ripped movies, that were already in your server, just pull it out and stick it in your laptop for the road.
We need to keep an eye on these!
The other problem facing the optical disc is the form factor. Its physical attributes severly limits its versatitlity and hampers engineering new players and recorders as they have to be able to hold and drive a disc. Would you rather have a Sansa flash based MP3 player or a portable CD player and a backpack to hold your collection?
The only time I use an optical disc now is to watch a movie at the house. I can't remember the last time I wrote to one except that it was to give to a co-worker so he could watch the same movie and I could keep the original at home.
Then, they cut their own throats and make it against the law to transfer the info to any other medium. You might as well buy something that you can move around anyway you want in even very pocket sized devices.

I can see a point in time when SD & HD (AVC) movies will be available cheaply on SDXC or similar flash memory. It's a long way off but inevitable given that the push for a stable, fast and highly portable storage medium is desirable.

Memory cards
Flash memory comes in different types and is used by all kinds of products, e.g. cameras, MP3-players, telephones. The great advantage of flash memory is the fact that it has no moving parts, so it is shock resistant and hardly wears. It is also very small and very light, which makes it perfect for use in portable digital devices.
