SDXC cards will be available in capacities up to 2TB

The Secure Digital (SD) format has come a long way since its original inception. Originally conceived as an offshoot of the Multimedia Card (MMC) format, SD cards have matured over the years into the Secure Digital High Capacity (SDHC) versions that are prevalent today for capacities greater than 2GB.

Current SDHC cards are artificially limited to just 32GB, which means that a new standard is being ushered in to boost capacities into the stratosphere. As a result, the new Secure Digital eXtended Capacity (SDXC) format was introduced today at CES. SDXC cards have a theoretical maximum capacity of 2TB and theoretical maximum read/write speeds of 300MB/sec.

The first SDXC cards will hit the market during the first quarter of 2009; however, these first generation cards will have a maximum transfer rate of 104 MB/sec.

"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 Gartner's Joseph Unsworth, research director, NAND Flash Semiconductors. "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."

"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 Canon General Manager Shigeto Kanda. "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."

We should expect to first seeing SDXC cards from the usual suspects such as SanDisk, Lexar, and Kingston. SDXC will more than likely carry a hefty premium over current SDHC cards, but expect to see that price differential close with time.

Compare those stats with SSD storage. lol

if silicon + profit for 16GB (Wafer thin tech) = $27. how can intel possibly defend $600 ish for a 60gig SSD thats massive in comparrison.

Im guessing the Milking times are getting shorter in this new age.

just wait until smart ppl's work out how to program I7 cpu's default settings with all those nice pins on the top of the chip.

Fun times ahead for slow/arrogant/greedy tech providers. :)

Why is it at least 6x the cost per gb? Why are we not all just throwing a bunch of SDHC cards together and running our computers on them? Why does the x-25m need all that extra hardware?

Well the write/read speeds are one. A good portion of cheap sdhc cards cant even write over 20 MB/s. The Intel drive can do something like 170. Normal hard drives can do between 70 and 100.

I also know it needs extra hardware to manage that data. Once instance that comes to mind is that flash can only be written a certain number of times before it wears out. This is ok for flash cards but hard drives can make small changes 100s of times. This drive would wear out in no time so it manages the writes in such a way that writes data evenly to make it last longer.

Its pretty new tech anyway which has considerable Research and Dev costs so they need to be sold for a premium to make back some of those costs.
