Conclusion

The U5 is a two-platter drive that's optimized for minimal power consumption and noise output. In this regard, it succeeds. The drive operates quietly and cool to the touch. It can be integrated into all systems without a problem.

Seagate takes pride in pointing out that the U-series drives are the most successful in history based on unit sales. Most readers, involved in IT or other computer-related professions, are bound to run into such drives. Even so, it's hard to recommend the U5 for those looking to build a low-cost machine or those looking for an inexpensive upgrade. The performance is simply not there. To its credit, the U5 is among the quieter drives we've used. It also features a robust three-year warranty. But there are other drives that offer similarly quiet operation combined with substantially better performance. In the end, it's those competing drives that offer the more attractive package.
