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


Even in theory, the hard drive was extremely easy to use, and it really came into its own in daily use. Plugging in the USB cable was all there was to it. Windows (XP) was able to recognize the hard disk as such without any problems and to install the necessary drivers in the system. However, the hard drive itself brings the driver with it, so that you do not need to insert any driver CDs. Nothing stands in the way of a spontaneous data exchange. In practical use, the drive has always proven to be helpful when large amounts of data had to be exchanged quickly between spatially separated computers. As a domestic ISDN user, for example, one has to reckon with very long loading times for larger downloads. Wouldn't it be just practical if the dedicated line in the company made various downloads overnight or during work and this data could be copied to the hard drive without major delays? However, copying will only proceed quickly if the external device is connected to USB 2.0. Here it is even able to compete with older desktop hard drives. If Iomega's hard drive is condemned to send the data over the bus according to the old USB 1.1 standard, the performance breakson the other hand noticeably, so that copying is associated with longer waiting times.

Incidentally, we have used the external USB drive as an alternative backup solution in the least cases. The drive is simply too fast for that to be misused for such 'low' work.


In general, the Iomegas 20 GB Portable Disk Drive surprised us positively. Even if the performance cannot compete with current high-end desktop hard drives, the device was able to assert itself as powerful, robust and particularly smooth running in our tests. But this performance on the USB bus also has its price. Compared to commercially available notebook hard drives, the small Iomega drive is twice as expensive, a 40GB desktop hard drive is already available for a good third for € 80, despite twice the storage volume. In any case, the 'portable hdd' is more practical than the Iomega USB 2.0 recorder that we recently tested. Anyone who is frequently on the move and receives large amounts of data from many places or has to deliver them will have real pleasure with the USB hard drive from Iomega and can access it without hesitation, at least when it is connected to the fast USB 2.0 bus. However, there is still some time to go before every newly shipped computer is equipped with the 480 Mbit/s fast interface standard.
