Remember way back in August last year, when Toshiba announced the “world’s first 64GB SDXC card”? Well, actually Panasonic was faster (even though that company waited until January this year with its announcement), and it already has been selling their own 64GB card [JP] in Japan since February. But starting this Saturday, Japanese users can choose between that and the Toshiba card, as announced [JP] by Toshiba today.
While the Panasonic card currently sells for just around $500 [JP] in Japan, the Toshiba model will cost a whopping $700 (we have no information on a release outside this country). Toshiba claims their class 10 card has a top write speed of 35Mbps and a read speed of 60Mbps. Theoretically, you’ll be able to handle a 2.4GB video file in 70 seconds.
And that’s not all. While SDHC cards max out at 32GB, SDXC card can store as much as 2TB, meaning some company is sure to roll out even bigger SDXC cards soon.
