Like Oliver Twist, we want some more. Memory, that is, to snap more photos or shoot more video. SanDisk, the world's largest supplier of flash data-storage-card products, has introduced an 8-gigabyte secure digital high capacity-format memory card. It is designed for new SDHC-compatible camcorders and digital still cameras with 5 megapixels or higher resolution. Besides having storage capacity to rival that of an iPod nano, the Ultra II SDHC card is as fast as The Flash - with write speeds of 9 megabytes a second and read speeds of 10MB a second. It adheres to the so-called SD 2.00 specification, which is required for cards and cameras to support capacities from 4GB to 32GB. The SanDisk Ultra II will cost about US$239.99 when it becomes available in June.
