Lexar Media today announced “the world’s first and only” 4GB CompactFlash memory card. The 4GB card stores about 600 images captured in RAW mode using a 6-megapixel professional camera, and as many as 45,000 JPEG images with lower resolution cameras, according to Lexar. It is speed rated at 40x, which is capable of a sustained minimum write speed of 6MB/s. The US$1,499 card is CompactFlash Type II and requires the host camera to support the FAT32 file system.
