IBM today announced that it is using just a few atoms of "pixie dust" to push back the data storage industry's most formidable barrier.
With AFC media, 100-gigabit data density could allow the following capacities within two years:
Desktop drives -- 400 gigabytes (GB) or the information in 400,000 books;
Notebook drives -- 200 GB, equivalent to 42 DVDs or more than 300 CDs;
IBM's one-inch Microdrive -- 6 GB or 13 hours of MPEG-4 compressed digital video (about eight complete movies) for handheld devices.
