Conclusion

As you can see by the insuperable performance gap, the USB drive simply cannot be compared to the two professional SCSI streamers. Of course the portable Travan streamer is a consumer product that is meant to be affordable by home and office users, and is therefore not streamlined for maximum performance. Still, $ 410 (the official price listed at Seagate's website) is quite high - it is the same amount you could spend on a 12-speed CD writer and 300 CD-R discs; but of course you could not make an easy 10 GB backup with CD-Rs.

The Tandberg SLR100 gave a good impression. At a price of $ 2600 it is naturally unaffordable for home users, but should prove very attractive to corporate network administrators. The software gives you every possible backup option, ranging from detailed scheduling of complete system backups, drive spanning and drive pool arrays all the way to complicated network backup solutions.

Seagate's Viper 200 is definitely the best, offering the highest capacity and best performance for backups. As far as I know there are only a few drives that are capable of beating this combination of capacity and performance, plus Backup Exec for Windows NT, Windows 2000, Netware and even IBM OS/2 Warp Server. However, such quality has its price, of course; be prepared to shell out at least $ 5500 for this baby.

It is not easy to recommend one particular drive. If you just want a single high-end streamer, the Tandberg has the better value. In terms of performance, the Viper 200 is currently unbeatable. Nevertheless, for some purposes (e.g. data safety by redundancy) and if cost is a concern, it might be better to get maybe five Tandberg streamers instead of two or three Vipers.
