Toshiba Ready To Release 64GB SDXC Card

Tweet

Toshiba’s North American division has developed the world’s first 64GB SDXC card, and they claim, the data can be transferred on and off the card at the fastest transfer rate ever for the SD card form factor. The fast transfer rates won’t just stop at the high-end SDXC cards – Toshiba is bringing the same transfer tech to their smaller, cheaper SDHC cards.

This spring, Toshiba will unleash three new SD cards, the aforementioned 64GB SDXC card, as well as a 32GB card and 16GB card of the SDHC variety. All three new cards will feature the new transfer tech, bringing you a speed of 60Mbps read and 35 Mbps write. Toshiba’s new high speed interface is called “UHS104″ and as you’d guess, is highly propitiatory proprietary.

All of the new cards will use CPRM copy protection to keep your data secure, and they’ll all use the standard SD card slots. The SDXC card will use Microsoft’s new exFAT file format (which is optimized for thumb drives, got to assume it’ll be handy on SD cards as well), while the smaller cards will use the more conventional FAT32.

The SDXC standard applies to all SD cards that will feature memory between 32GB and 2TB of storage. The older SDHC standard fits for 2GB and 32GB of storage.  As you can imagine, these cards won’t be cheap. No word on pricing has been announced, but speculation has the SDXC 64GB card cost in excess of $600+.
