Secure Digital Hi Capacity coming

Panasonic SDHC 4GB card

Secure Digital cards with capacities of 4GB and greater are coming. Given that most SD cards seem to have topped out at the 2GB mark, this could be a good thing. Known as SDHC (Secure Digital 2.0 Hi Capacity), the cards should reach capacities as high as 32GB. Unfortunately (you knew that there had to be a catch), they will only work in devices that come with a SDHC-compliant slot.

Panasonic and PQI are set to release 4GB SDHC cards which will support transfer rates up to 6MB/s. Prices are expected in the vicinity of $250 USD.
