Back Up on the Go

If a computer crash hasn't already taught you the importance of backing up files consistently, purchase an external hard drive as a pre-emptive security measure against a technical (and mental) breakdown. There's no need to be intimidated: New, smaller models make file backup just as easy on the plane as in the office. Here are our top picks.


1. Maxtor OneTouch III Turbo (1 TB)
A good option for a desktop computer, the OneTouch III Turbo packs a punch. The price is right for the drive's impressive one-terabyte storage capacity (equal to 1,000 gigabytes or several million stored digital photos) , high-speed connections (USB 2.0 and FireWire 400 and 800 ports), and backup software, all within a
reasonable size (6 x 3.9 x 8.5 inches). Fast, and Mac- and PC-compatible, the OneTouch also boasts RAID capabilities-a disk subsystem that reads and saves data across multiple drives for increased performance and security-and a single-touch backup system with password protection. $899.95



2. Lexar JumpDrive Lightning (2 GB)
Packaged in a stylish stainless-steel case, the JumpDrive Lightning is named for its fast, 24 MB per second read speed and 18 MB per second write speed. This small drive (3.05 x 0.87 x 0.43 inches) is perfect for the business traveler who wants a fast, portable, and compact file-storage solution; as with any USB flash drive, just plug it into your computer's USB port (Mac or PC). Preloaded software and file synchronization let you install and run the drive without opening any additional applications. And the flash drive's data encryption support and password protection ensure file security if the drive is lost or stolen. $159.99



3. LaCie Safe Mobile Hard Drive with Encryption (120 GB)
LaCie takes the name of its hard drive seriously. The Safe Mobile Hard Drive's functionality covers all data protection issues: Fingerprint access control replaces forgotten passwords and lost smart cards, ensuring file confidentiality while traveling, and the added data encryption capability protects against hackers. Plugging directly into your computer's USB port, the LaCie is slightly bigger (3.15 x 5.43 x 0.98 inches) than most mobile drives, but can fit into your pants' back pocket, and weighs only 8.11 ounces. It is both PC- and Mac-compatible. $349.99



4. Western Digital Passport (120 GB)
About the size of a standard passport, this portable hard drive offers sizable storage (it can hold up to 34,000 high-resolution digital photos) at a reasonable price. Durably built with a protective cover that claims shock-absorbing capabilities, the Western Digital Passport is easy to install on both Macs and PCs. Its accompanying USB cable powers the hard drive directly from your laptop, making an external adapter one less thing you need to fit in your suitcase. $199.99
