Seagate Technology will begin shipping its first widely available hard drives with built-in encryption next year. The Momentus 5400 FDE.2 (Full Disk Encryption 2) will include a special encryption chip that will make it impossible for anyone to read data off the disk, or even boot up a PC, without some form of authentication. Designed for notebook computers, the 2.5-inch, 5,400-RPM drive will come with a storage capacity of 80GB, 120GB or 160GB.”]
