Western Digital has introduced two new portable storage devices:
40GB and 80GB Passport hard drives
that feature USB 2.0 connectivity and bus-powered operation, eliminating the need for a separate power supply. Their interiors contain 5400RPM 2.5-inch Scorpio EIDE drives and Data Lifeguard protection against data loss, while their exteriors offer shock-absorbing cases. Western Digital expects to ship them next month for US$199 (40GB) and $249 (80GB). Mac OS X v10.1.5 is required.
