Samsung's 8Gbyte memory card

Samsung Electronics Co. Ltd has developed an 8Gbyte microSD flash memory card designed for use in today's multimedia cellphones. Claimed to feature the highest capacity today for a microSD card, the device can store 2,000 MP3 music files, 4,000 digital photos, or approximately 5 DVD-quality movies, said the company.

SD cards, to date, have been largely used for data storage in digicams and increasingly in TV sets. MicroSD cards, which are a quarter the size of an SD card, are backward compatible with SD cards using an extender, to allow multimedia files downloaded by mobile phones to be easily displayed on other media.

With a read speed of 16MBps and a write speed of 6MBps, Samsung's 8Gbyte microSD card exceeds the speed class 4 Secure Digital High Capacity standard which requires a data write speed of 4MBps. This is also much faster than the SD speed class 2 designation carried by available microSD cards.

Dataquest predicts that the memory card market as a whole will average 10 percent annual growth between 2006 and 2010, while demand for high density 8GB cards set to grow 2.6 times annually over the same period. By 2010, the 8GB memory card will be the market mainstream in terms of units sold.
