forskel på m XD og h XD kort

http://en.wikipedia.org/wiki/XD-Picture_Card#Type_M_and_Type_H_cards

The original xD cards were available in 16 MB—512 MB capacities. The Type M card, released in February 2005 [2], uses Multi Level Cell (MLC) architecture to achieve storage capacities up to 8 GB. As of 2006, Type M cards are available in sizes from 256 MB to 2 GB. However, the Type M suffers slower read-write speeds than the original cards.

The Type H card, first released in November 2005 [3], offers higher data rates than Type M cards (theoretically as much as 3 times faster).[4] As of 2006, Type H cards are only available in 512 MB and 1 GB capacities. It also includes special "picture effects", although most of these are only available in use with Olympus digital cameras.

Due to changes in the cards' storage architecture, newer Type M and H cards may suffer compatibility issues with some older cameras (especially video recording). Compatibility lists are available for Olympus (PDF format) and Fujifilm. The newer cards are also incompatible with some card readers.
