spmug 572 Choosing a Backup Buddy By J. D. BIERSDORFER Q. Which is better for backing up the computer on the road - a flash-memory drive or a portable hard drive? A. Finding the right type of drive for backups on the go depends on a few factors, like how much data you intend to back up, how much gear you want to haul and how much you want to spend. Flash-memory drives (those handy lightweight devices about the size of a disposable lighter) have no moving parts and plug right into the computer's U.S.B. drive. The physical size and durability of the average flash drive makes it a good choice for travel if you don't need to run a full backup of your system on the road. Although they currently don't hold as much data as the average hard drive, 4-, 8-, and even 16-gigabyte flash drives are now available, which may be more than enough for backing up recent files and other data. Flash memory prices have come down in recent years, and you can find four-gigabyte flash drives from a variety of makers for $180 or less. External hard drives have gotten much smaller themselves in recent years and provide much more storage space for the price; Maxtor's OneTouch III Mini Edition drive, for example, weighs less than eight ounces, stores 100 gigabytes of data and costs less than $160. Traditional hard drives contain moving parts that eventually wear out and may suffer more than flash drives if dropped onto an unforgiving surface, but most of these hard drives designed for travel and portability come in sleek, sturdy cases to help withstand the stress of life on the road.
