SD Association to show off SDXC at CEATAC 2009

SD Association to show off SDXC at CEATAC 2009 The SD Association will lead a public technical discussion at CEATAC on October 7. Secure Digital eXtended Capacity (SDXC) cards come in the same size card as regular SD cards, but have the potential to offer up to 2TB storage on a card the size of a stamp. SDXC accelerates SD interface read/write speeds up to 104 megabytes per second.
The SD Association will have a road map for data transfer bus interface speed up to 300 megabytes per second in the coming months. "The SDXC memory card specification creates innovative content and media opportunities for manufacturers and service providers and transcends removable memory’s traditional role in consumer electronics strategies," said James Taylor, president of the Alliance.

"At CEATEC, we'll reveal the SDXC memory card specification from the perspectives of memory card and device manufacturers and users. We'll also look at the many benefits and opportunities manufacturers and service providers win by implementing this new technology."

The SDXC memory card specification provides the portable storage and speed needed to store weeks of high-definition video, years of photo collections and months of music. It can be used in mobile phones, cameras, camcorders and other consumer electronic devices.

i find the Whole SD (new extensions here) is confusing as hell for the consumer you have SD SDHC SDIO SDXC not to mention they all look identical.

99% of the public will be confused by the new "SDXC" bit because it's no different, on the outside, from SD/SDHC cards. At least they are all backwards compatible.

While these will be outrageously expensive when they first are released I could see movies eventually being released on SDXC (or whatever comes out after that) cards due to their high storage potential and decent speed rates.

I wonder how long it will take (and how crazy the price will be) to get 1TB SDXC cards out. Right now the highest capacity is 32GB for an SDHC and they cost $74 to $120 online.

If these aren't too expensive, which they probably are, I want to get one for my BD-Player, and one for PC backups. 4TB in my pocket, I'm drooling now.

Well according to the "SD Association" (see here) SDHC can store up to 32GB and SDXC can store up to 2TB.

Considering 32GB SDHCs are $74+ online, I guess that SDXC cards would start at ~$80 and go way up from there. However, the price of SDHC cards comes down rather quickly so we could possible see $50 1TB SDXC cards in five to ten years.

I remember that about 3 years ago some company made an announcement that they would have a 1 TB flash drive by late 2008. If they are only a year or two behind, then this might be an ideal format for their new technology.

Also, 32GB SDHC is no longer a high density chip. If not for the 32GB limit, it would not be difficult to make a 64GB (or larger) SDHC card. The only reason that they still cost so much is that they are the largest size currently available. This, combined with the fact that SDXC will not work with most existing devices such as cameras, camcorders, media players, etc should make the price of 64GB cards rather affordable.

"While these will be outrageously expensive when they first are released I could see movies eventually being released on SDXC (or whatever comes out after that) cards due to their high storage potential and decent speed rates."

This would require either a "burned" card or a custom circuit card. Either way, the price is at least half that of reusable flash. Considering that BluRay movies cost less than $2 to make (including case), I doubt we will see a lot of SDXC movies any time soon.

Yes, very expensive. Just look at the Blue Ray disks. You know they probably cost 10 for a buck to make. It is just a way to extract more from the consumer. Blue Ray movies can fit on a dual layer DVD without much if any image loss. However, there would be no space for adds.

It will be cheaper to put them on yourself. 100 HD movies on a tiny chip!

KillerBug, I remember that new release. I guess that company went under.
