Iomega HDD 20 GB in the test: External hard drive for USB 2.0

Requirements & Commissioning

A USB 2.0 controller is not required for operation, but is necessary to ensure the performance of the external drive to bring to bear fully. If a PC forms the basis of operation, a USB 1.1 controller as well as Windows 98 (only USB 1.1 possible), Windows 98SE, Windows Me, Windows 2000 Professional or Windows XP are required for successful commissioning.

Unfortunately, Linux is expressly not supported. For the Apple Macintosh, it should be at least a G4, G3 or iMac with MacOS 8.6 or higher and at least MacOS USB v1.3.3, which of course includes all versions of MacOS X. In our tests, however, we limited ourselves to Windows XP Professional. Since the drive is fully plug-and-play capable, it is recognized as an additional hard drive after plugging in and displayed in My Computer. There is no need to restart the system - it couldn't be easier.It is also possible to disconnect the mass storage device from the bus during operation. However, it is advisable to inform Windows beforehand that you are thinking of snatching the hard drive from the system in the next moment. If Windows write caching for external drives is deactivated by default, this is not even necessary. We will deal with the pros and cons of write cache in more detail in the next section of the review.


Although software is not absolutely necessary for a hard drive, Iomega delivers the portable HDD synchronization software (QuickSync 3) and backup software (Iomega Backup). The name QuickSync is a bit confusing here, as it is more or less a simple backup software that runs in the background and constantly keeps the backup folder up to date. However, the files are not compressed.

This is where the software differs from Iomega Backup, atwhich a compressed image file can be created. However, the software is not absolutely necessary for normal use of the hard disk and those who only use it for fast data transport will rarely work with the software anyway.
