SD, or Secure Digital, cards are widely used in devices such as digital still cameras. The higher capacity will mean users with large data storage requirements won't have to carry around as many cards. The 1GB card should be able to accommodate around 2000 images taken at 1,600-pixel by 1,200-pixel resolution. It should also be able to store about nine hours of MPEG4 video or 16 hours of MP3 audio.
The company expects the cards to cost around $500, says Bob Goligoski, a spokesperson for SanDisk.
