TechArp takes a look at the Seagate 750GB Pushbutton Backup External Hard Drive:

Performance-wise, the 750GB Pushbutton Backup had faster read and burst speeds than the VIZO Luxon USB enclosure which we paired with the 750GB Barracuda 7200.10 hard drive. However, the Pushbutton Backup drive was about 9% slower than the Luxon enclosure in the High-End Disk WinMark 99 test. Other than that, both drives had about the same performance characteristics. Since the Pushbutton Backup drive is using the same 750GB Barracuda 7200.10 hard drive or a similar model to the one used with the VIZO Luxon enclosure, any performance difference is due to the SATA-USB controller used. It's good to see that the Pushbutton Backup's controller is no performance slouch.

However, those who buy the Pushbutton Backup will not be buying it merely based on its performance. Its large capacity will be a major sell factor, offering more capacity than competing backup solutions. Those who require a lot of backup capacity will certainly be interested in this drive. Potential buyers will also be interested in its ease of use and reliability. While we can attest to its ease of use (it literally works out of the box!), we find the 1-year limited warranty quite peculiar since the Barracuda 7200.10 hard drive itself comes with a 5-year warranty. Seagate should really give the Pushbutton Backup drive an equivalent warranty.

In conclusion, the Seagate 750GB Pushbutton Backup is really not for everyone. If you are a hardware enthusiast, it would be better and cheaper to buy a Seagate 750GB Barracuda 7200.10 hard drive and install it into an external USB hard drive enclosure. You will even have full 5-years of warranty on the hard drive.
