SanDisk's topline memory cards tend to be among the fastest when tested for recording pictures in cameras. The company has a new line, called Extreme III, which records data at 20MB/sec.
The catch: just because the card can read data that fast doesn't mean the camera can feed data at that speed. A possible advantage is faster delivery of photos to the computer via a USB v2 reader: a 4GB card theoretically uploads in 3.5 minutes, instead of 7 minutes or longer for current cards.
Cards will ship in October or November. Prices will range from US$140 (1GB) to $560 (4GB), have a lifetime warranty, and include RescuePRO software for recovering accidentally deleted images (no mention if it recovers data from re-formatted cards).
Meanwhile, the capacity of its Ultra II has been increased to 8GB in the CompactFlash Type I form factor. The Ultra II writes at 9MS/sec and reads at 10MB/sec. The US$960 card won't be avaialble until November.
