| The Bottom Line | We're impressed by the Lenovo ThinkPad USB Secure Hard Drive's burly security features and rigorous performance results, but the bloated price tag prevents us from recommending it to anyone other than business consumers. If you're shopping for an external hard drive, competing drives give you a cheaper cost per gigabyte in a fancier package. | Small business and personal users with large amounts of data will appreciate the Clickfree's painless backup drive that practically automates all the work through the embedded software. People running older Windows operating systems are out of luck, but the lightning-fast transfer speeds and excellent performance scores secure the Clickfree a solid recommendation for up-to-date Windows and Mac users. | While other external hard drives offer built-in backup software, automatic data encryption, or rugged casing protection, the Transcend StoreJet 25F only promises, and delivers, the fastest data transfers at the lowest price. The missing FireWire prevents us from giving this Transcend an Editors' Choice award, but we still highly recommend this drive to storage hounds who don't mind USB 2.0. | The Seagate FreeAgent Go is our favorite portable hard drive to date and takes our award for Editors' Choice. The drive is well designed and fast, and you won't find a better value for the price. | Mac and PC users alike will appreciate the Iomega eGo Portable's triple interface connectivity that lets you choose from USB 2.0, FireWire 400, and FireWire 800. Combined with a rugged enclosure, free data protection software, and a robust three-year warranty, this drive is a great example of well-rounded hardware. We thoroughly recommend it both for average consumer as well as data-hounds on a budget. |
