In an August 4, 2009, press release, Toshiba Corporation announced the launch of the world's first 64GB SDXC (extended capacity) memory card capable of complying with the new SD memory standard, version 3.00, UHS104. Toshiba also announced 32GB and 16GB SDHC memory cards compliant with the new memory standard.
The new SDXC and SDHC memory cards are the first memory cards compliant with SD memory standard version 3.00, UHS104, which brings a new level of ultra-fast read and write speeds to NAND flash based memory cards: a maximum write speed of 35MB per second, and a read speed of 60MB per second.
