JMicron could be the solution

Secure Digital (SD) and Secure Digital High Capacity (SDHC) flash memory cards are commonly used in devices like digital cameras, laptop computers, and camcorders. Their high capacity and low cost can be attributed to die shrinks as the pace of semiconductor technology moves forward.

SD cards have a maximum capacity of 4GB, while SDHC cards can go up to 32GB. Although this may seem like an extreme size, high-definition camcorders and digital photography enthusiasts have been pushing for a new format with higher maximum capacities and faster transfer speeds.

The industry answered earlier this year at the 2009 Consumer Electronics Show with the Secure Digital eXtended Capacity (SDXC) format, which has a maximum theoretical capacity of 2TB and could eventually reach speeds as high as 300 MB/s.

Although there were many promises made, there aren't really any SDXC cards that you can buy. A large part of the problem is due to the old chicken and egg paradigm; no one wants to produce a large, expensive, niche product if there are no SDXC card readers that can support the new format.

The SDXC format allows for backwards compatibility, meaning that readers should be able to use older SDHC, SD, and MMC cards. Development work has been slow, and the big push for products supporting SDXC won't occur until next year. The first wave of products will show up at this year's CES.

Many of those products will integrate SDXC card readers made by JMicron through a PCIe bus. JMicron's SDHC readers are commonly used in the industry and integrated into laptops, mobile phones, and digital cameras.

JMicron is also working on a standalone card reader that will be pluggable into a USB 3.0 slot. The company states that "PCIe or USB 3.0 interfaces are needed to unleash the full potential" of SDXC cards. Ultimately, read and write speeds will be determined by the flash memory card manufacturer, just as it is for SDHC cards.

The trend in the electronics industry for the past 50 or more years has been that new products are introduced to the marketplace in low quantities and high prices. There are always some early adopters willing to pay to have the latest and greatest.

Eventually costs go down as productions ramps up. That's how it works. So if you just say "no need" based on your needs then we'll never have affordable new products in the market. Think about it.


CD Players
DVD Players
BD Players (look to be catching on)
CD and DVD burners for computers
Flat screen monitor/TV technology

If someone said "no need" when a 40" $15,000 flat screen TV was about to be introduced then we'd probably be set back 5 years or more in flat screen TV/monitor technology and pricing.

Finally, I have an HD camcorder and would like a faster card for card to PC transfers. Also as recording bitrates go up for newer cameras more capacity would be welcome.

Thank you and good night.

No worries, the tech is there to produce higher capacities. It just needs market demand to get them out and cheaper. Hoping for the 1TB flash soon :D

4 slot SDXC chassis with SATA connector for SSD with 4 2TB cards gives a laptop an 8TB "hard drive".

Might take a day or two to back up, but it would be a week or two before you run low on space :P

Replacement of worn out memory modules becomes plug and play :)

For now I'll take it with 4x128GB to replace the 120MB HD shipped with my lappy. I'm sure I can find some way to use the extra space. Not sure of the speed, but the low power consumption would do just fine.
