New ‘dual-row pin' SD cards promise up to 300MB/s

The SD Association has announced that as part of their continuing development of the SD 4.0 standard, new ‘dual-row pin’ SDXC memory cards will soon be available.

The new design allows cards to increase read/write speeds up to 300MB/s for both SDHC and the more recent SDXC memory cards. Devices that include this new ‘dual-row pin’ technology will remain fully compatible with all pre-existing SD, SDHC and SDXC memory cards. The technology passes the higher speed signal through the second row of pins, whilst keeping the other row of pins for legacy devices that don’t support this standard.

Norm Frentz, chairman of the SD Association, claims that “SD can now support high definition video from Hollywood movie studios, television broadcasts, or HD videos taken on your latest vacation.” He also goes on to state that the SD Association is dedicated to maintaining the “value usefulness and longevity” of products built around the highly-popular SD memory card ecosystem.

Currently, Ultra High Speed (UHS-I) SD cards have the highest data transfer speed in the SD range, at around 104MB/s. The new card format is expected to reach shelves in early 2011.

I won't say no to 300 MegaBytes a second transfer rate. May use these on a Netbook instead of SSDs if cheaper.

hopefully they bring it to microSDxC speed is as equally important as capacity when shooting HD stuff so don't have like some of android phones atm get when shooting 720p ends up looking like fail and when new dual core mobile chips come around with 1080p capabilities.

Well, if they can transfer up to 300mb/s, then people should soon be able to just set their digital SLR's to continuous and hold down the shutter button...

Will these work on older devices, and can they do basically the same with Mini's? Would love that speed of card on my android device.

I don't know all the terms for these cards, so I wasn't sure if that covered all devices, or if certain ones were only what they explained. And no answer to the 2nd part of the question, rip off

Size doesn't matter...

She lied to you
I like the fact that this will still work on older devices by just providing an extra set of pins that are optional to use

Well you know, the SDXC standard supports up to 2 TB cards, so it is possible :-)

Manufacturers expect Terabit flash chip will be coming in 2012. We will have a 2TB card if they manage to squeeze 16 Terabit flash chips into one SD card PCB.
