Toshiba has announced the development of three new SDHC cards, due in the next several months. Most prominent is what the company calls the world's first 32GB card, finally achieving the maximum capacity of the format. SDHC sizes have typically been limited to 4 or 8GB. A lesser, 16GB card is also in the works, and users of mobile phones will be able to get an 8GB microSDHC card. Crucially, Toshiba has chosen to make the cards Class 4 (4MB/s) models, unlike many first-wave cards which have defaulted to Class 2. The 16GB Toshiba card should ship worldwide in October, with the 32GB and 8GB cards arriving in January 2008.
