Fast and slow SD Cards

Semantics John :-)

Try http://www.sdcard.org/developers/tech/sdxc/

Or to quote....

The next-generation SDXC memory card specification, released to members in
April, 2009, dramatically improves consumers’ digital lifestyles by
increasing storage capacity from more than 32 GB up to 2 TB and increasing
bus interface speed up to 104 MB per second in 2009 with a road map to 300
MB per second.

You really should stop trying to score points by giving only part of the
story, John.
