The Bottom Line: A sexy, slim design and backup software set make a compelling argument for the Seagate BlackArmor PS 110 external hard drive. We like the unique Try and Decide feature preloaded on the drive, and the throughput speed scores stomp the competition. Shoppers on a strict budget should look into the Fujitsu Handydrive for the best cost per gigabyte, but the BlackArmor PS 110 offers many extra features for just a few more dollars more.
