UHS spec promises ultra-fast transfers
The SD Association today defined a new specification for very fast SDHC and SDXC cards. Ultra High Speed I (UHS-I) will guarantee a maximum interface speed of 104MB per second, or four times the 25MB speed of regular cards. As long as they're used with cameras, readers or other devices that can recognize the speeds, UHS cards should have no trouble recording HD video or shooting continuous RAW photos.

New storage card also allows faster file transfer
SanDisk announced that it has begun shipping its new 64GB Ultra SDXC card. The flash media can store approximately eight hours of typical HD video, and can transfer data at up to 15MB per second. Devices compatible with the new SDXC format have only recently been introduced, and include Canon's new VIXIA camcorders and PowerShot cameras. The extra capacity doubles that of the largest SDHC memory card.

exFAT to be used on many more devices
Microsoft today said it would license its exFAT file system to third parties to spread its use in computers and portable devices. The technology is already found in the SDXC card format but will now be available in a flexible system that depends on the device. Simple devices like cameras and photo frames will involve a pay-once $300,000 fee, while more advanced devices like computers and smartphones will pay a royalty for every unit sold.

Dell, HP, Lenovo to use new card format
Notebook designers are planning to add SDXC to their systems in sync with the mobile Core i3, i5 and i7 processors launching early next year, a purported leak said today. At least Dell, HP and Lenovo are believed to be engineering their notebooks to use the new card format at the same time as they switch to the 32nm processors in January. It would give the PCs recognition of cards up to 2TB in capacity and transfer speeds faster than current solid-state drives, at up to 300MB per second.

SDXC Card Format
The SD Association today revealed first details of SDXC (Secure Digital Extended Capacity), its sequel to the current SDHC standard for flash cards. The format uses the exFAT file system to dramatically increase the maximum storage space from the arbitrary 32GB of SDHC to a full 2TB and would be enough to hold roughly 4,000 RAW photos or 60 hours of HD footage. Notably, the format also no longer sacrifies speed in the process, according to the organization. Unlike SDHC and other card formats, the fastest speeds should be possible even at the 2TB limit.
