January 7, 2009 | Mark Goldstein | Digital | 18 Comments | |

SDXCSDXC is a next-generation memory card format, with up to 2 terabytes storage capacity and read/write speeds of 300 megabytes per second. SDXC (eXtended Capacity) will provide maximum speeds even when it achieves its maximum 2TB storage capacity. “SDXC is a large-capacity card that can store more than 4,000 RAW images, which is the uncompressed mode professionals use, and 17,000 of the fine-mode most consumers use.” said Shigeto Kanda, general manager at Canon. Developed by the SD Association, specifications for the new SDXC standard will be released in the first quarter of 2009.

SDXC Memory Cards Provide Consumers with Massive Storage, Incredible Speed in Familiar, De Facto Standard

LAS VEGAS – CES Booth South 3 #31277 – Jan. 7, 2009 – The next-generation SDXC (eXtended Capacity) memory card specification, announced today at the 2009 International CES, dramatically improves consumers’ digital lifestyles by providing the portable storage and speed needed to store weeks of high-definition video, years of photo collections and months of music to mobile phones, cameras and camcorders, and other consumer electronic devices. The new SDXC specification provides up to 2 terabytes storage capacity and accelerates SD interface read/write speeds to 104 megabytes per second this year, with a road map to 300 megabytes per second.

The SDXC specification, developed by the SD Association, leapfrogs memory card interface speeds while retaining the world-leading SD interface. Specifications for the open standard will be released in the first quarter of 2009. SDHC, Embedded SD and SDIO specifications will also benefit from the new SD interface speeds.

“SDXC combines a higher capacity roadmap with faster transfer speeds as a means to exploit NAND flash memory technology as a compelling choice for portable memory storage and interoperability,” said Joseph Unsworth, research director, NAND Flash Semiconductors, at Gartner. “With industry support, SDXC presents manufacturers with the opportunity to kindle consumer demand for more advanced handset features and functionality in consumer electronics behind the ubiquitous SD interface.”

Turning mobile phones into media centers
SDXC allows users to enjoy more from their mobile phones. Larger capacity and faster transfer speeds allow for expanded entertainment and data storage. A 2TB SDXC memory card can store 100 HD movies, 60 hours of HD recording or 17,000 fine-grade photos.

“With SDXC, consumers can quickly download higher quality content to their phones, including games, video and music – giving consumers a richer media and content experience,” said James Taylor, president of the SD Association. “The SD interface already has proven itself valuable in mobile phones. Now, SDXC memory card capabilities will spur further handset sophistication and boost consumer content demand.”

Shooting pictures at the speed of life
SDXC is also the first memory card specification to provide 2TB storage without hindering the high-speed performance necessary for high-end photography. It will provide maximum speeds even when the SDXC specification achieves its maximum 2TB storage capacity.

“SDXC is a large-capacity card that can store more than 4,000 RAW images, which is the uncompressed mode professionals use, and 17,000 of the fine-mode most consumers use. That capacity, combined with the exFAT file system, increases movie recording time and reduces starting time to improve photo-capturing opportunities,” said Shigeto Kanda, general manager at Canon. “Improvements in interface speed allow further increases in continuous shooting speed and higher resolution movie recordings. As a memory card well suited to small-sized user-friendly digital cameras, the SDXC specification will help consumers realize the full potential of our cameras.”

SDXC will enable camcorders to provide longer, professional level HD video recording with a small form factor.

The SDXC specification uses Microsoft’s exFAT file system to support its large capacity and interoperability in a broad range of PCs, consumer electronics and mobile phones. The exFAT system was designed for increased compatibility with flash media, from portability of data to interoperability with multiple platforms and devices on removable media.

“The SD Association is committed to answering and anticipating consumer demand for easy-to-use memory card storage that is interoperable in any device with a matching SD slot,” Taylor said. “The SDXC card gives consumers a new, yet familiar, high-performance card that will be used in hundreds of manufacturers’ device offerings.”

SD Association
The SD Association is a global ecosystem of more than 1,100 technology companies charged with setting interoperable SD standards. The association encourages the development of consumer electronic, wireless communication, digital imaging and networking products that utilize market-leading SD technology. The SD standard is the number one choice for consumers and has earned nearly 80 percent of the memory card market with its reliable interoperability and its easy-to-use format. Today, mobile phones, Blu-ray players, HDTVs, audio players, automotive multimedia systems, handheld PCs, cameras and camcorders feature SD interoperability.

That sucks that most professional camera's use CF cards (with a few exceptions of course). Still neat nonetheless.

The math on what 2TB can hold seems drastically off. I can store 200-250 RAW files on my 4GB card currently. 2TB is 512x the size. Unless my math is way off, you should be able to store over 100,000 raw files on 2TB.

Internal memory indeed is a necessity to have if you are into photography even if you are a professional one or to photos just for fun ...

Thank you for the article

All goes well for HD Video and Raw Images on Pro Cameras - however they (the Pro Cameras) still use CF cards? Perhaps the technology will move across to CF cards or we might perhaps find the newer Pro Cameras start using different card technology? Also looks good for new generation laptop HD's?
Still have to teach people to back up however - more and more are loosing data as the cards now hold more and thus people are less prone to 'do' something with the images!

the photo industry should consider including internal ssd hd's for sure.

Does this mean that this new technology will be compatible with my camera now, or do we need to purchase new equipment?

So what's in the pipe line for DVD Video Cameras?
My Video camera takes 1.4GB mini DVD disks.
Can it be modified to take advantage of newer technology,or do I have to get another camera?

I see alot of complaints above about the professionals using CF cards? Why can't they still use the SD with a SD to CF adapter?

What about the compatibility issues? Will it work with my SDHC card reader or do i have to purchase another reader for it? Apart from that, it has a very bright future.

That's just the possibility of losing 6 months worth of digital photos instead of just one week's worth. I've found quite a few lost SD cards in my life! IMHO Compact Flash, although bigger, offers more ergonomic handling. Oh and let's not forget...when was the last time you made notes on the back of your SD card? Finally...just how long would it take to download a 2TB SD card into your hard drive and what kind of humongous optical will you be archiving it on??

From what I've read, there will be new SDXC hardware that will be backward compatible to be able to use SDHC and even SD from before that. Alas, like the SD to SDHC transition, we won't be able to use the new media in old hardware. So no, we won;t be able to use SDXC cards in SDHC cams. Another thing I read however, is that the 32GB limitation put on SDHC is arbitrary and that it could theoretically go up to 2TB as well, although the bus is maxed and won't come close to SDXC bus of 300mbps

I really want to get one of these kinds of cards. They look interesting, especially their high capacity. This would be a great card for storing thousands of pictures or backing up my computer's hard drive.

does anyone else find that amazing that 2TBs can be stored on a quarter sized card? With that knowledge in mind im not surprized that portable devices havent spiked in their thresholds. that would be cool to see, storing a lifetime of data in a little card which you can put on your keychain.

I hope they allow other formats besides AVCHD, Maybe a patent free format it does not matter if it has less compression ratio (in 2TB).

It seems that sdxc memories will be affordable.
Now a 32GB class 4 takes like one hour to copy into a 5400rpm hdd, a class 6 or 10 is very expensive.

It would be great if they chose other formatting different than FAT32 for the memory, FAT32 can just hold files up to 2GB, that is stupid for video recording. There are many other formats safer and allow bigger sizes. It is needed for editing.

If you share my opinion, please help asking manufacturers to include this features.

The SDXC format is "exFAT" which allows virtually unlimited file size, so the 2GB problem is gone, if the camera/etc firmware doesn't get in the way. So, 22 min limit on a 1080 HD video should also "go away". I'm almost ready, but finding people on the phone at companies which make the cameras who have more knowledge than you can find searching the internet is a RARE thing. They really should learn about their own products! For example, look up "" for the page on SDXC, it lays it all out pretty well. But, do the cameras just accept them, but format them as FAT32 (2GB limit), or do they use exFAT and fix the problem? Maybe a test in a store is in order.
