No room on a crowded desktop or in a loaded briefcase for PC backup? Edge Tech Corp. begs to differ, introducing two sizes and ten capacities of portable hard disks with USB 2.0 interfaces and Softland's Backup4all software. The DiskGo 2.5-Inch Backup Ultra Portable Hard Drive draws its power from the computer's USB port; it measures a trim 5.3 by 3 by 0.5 inches and weighs 13 ounces. Available capacities range from 40GB ($115) to 160GB ($350). The AC-powered, 3-pound DiskGo 3.5-Inch Backup Portable Hard Drive holds from 80GB ($105) to 400GB ($320) of folders and files. All DiskGo prices are before mail-in rebates.

Meanwhile, Iomega Corp. has supplanted the 35GB version of its swappable, ruggedized 2.5-inch storage device with a new 70GB Rev Backup Drive ($580 with ATAPI or $600 with USB 2.0 interface). Twenty percent faster as well as twice as roomy as the Rev 35, the fully backward-compatible drive comes with one 70GB module; additional 70GB disks are priced at $69 each or $250 for a four-pack.
