Seagate on Monday announced it has teamed up with virus-protection software developer McAfee to develop its self-encrypting notebook PC hard drives from its Momentus Full Disk Encryption (FDE) line, in both 7200RPM and 5400RPM versions. Both are now available in 320GB capacities, or the highest of any FDE drive on the market, and Seagate promises to introduce even larger, 500GB versions soon.
