question is - how much faster? is it significant?
According to
http://www.olympusamerica.com/cpg_section/cpg_xd.aspHi-Speed xD-Picture Card (Type H) 
In addition to outstanding reliability and storage capacity, the Type H card provides improved write speeds
(up to 2x to 3x faster than previous xD cards) so photos and QuickTimeŽ movies will be saved and formatted to the card quicker, meaning less time to wait between shots. Each Type H card also comes with a unique authorization code for OLYMPUS Master 1.4 software that when entered, enables you to use new editing features including:
* Watercolor
* Oil Painting
* Cartoon Art
* 3D photos
By adding the ART function to OLYMPUS Master 1.4 you can quickly and easily turn any photo into a unique Watercolor, a vibrant Oil Painting, fun Cartoon Art, and even convert it (including Panoramas) into a cool 3D version.
Standard xD-Picture Card (Type M) 
The Type M xD-Picture Card keeps your photo, movie and other files safe and sound so you can enjoy them any way you want (viewing, sharing, slideshows, etc.) and any time. The compact size lets you carry it anywhere and because it's compatible with many reader/writers, you can download data to a computer or another device in a jiffy.
As you can see, the type H XD card is claimed to be up to 2x to 3x faster than previous xD cards.
