Seagate BlackArmor PS 110 review

Editors' note: Updated drive manufacturer name.

Seagate's new 500GB BlackArmor PS 110 external hard drive ($160) provides trustworthy storage and data backup solutions for the consumer who needs more space. The shape and design of the drive isn't a far departure from the FreeAgent Go, another thin external HDD from Seagate. The PS 110 isn't the cheapest drive out there, but the ample backup software suite speaks to the value of this drive. If you're craving more portable storage for your indispensable data, you'll appreciate the versatility of the Seagate BlackArmor PS 110 hard drive.

Design
The Seagate BlackArmor PS 110 replicates the same thin profile of its older brother, the Seagate FreeAgent Go, measuring a very pocketable 5 inches long, 3 inches wide, and half an inch high. In contrast to the Go's array of bright colors and multiple capacities, the BlackArmor distinguishes itself and offers only one 500GB model in matte black. The downward bend at the bottom of the device creates a unique silhouette, with only one USB 2.0 port that sits on the top face. We're a bit disappointed that there isn't FireWire access here, mostly because we've recently been spoiled by the Iomega eGo Portable Mac Edition, an Editors' Choice winner for its triple-interface (USB 2.0, FireWire 400, FireWire 800) connectivity. The drive is compatible with Windows and Mac OS (with a quick format), but if you're a Mac user hoping to benefit from FireWire's drastic speed benefits, you'll find that Iomega can give you a faster all-around drive.

Features
Seagate put substantial effort into beefing up the preloaded software on the drive, and it shows: the BlackArmor Backup software is one of the most comprehensive dashboards for backups and restorations we've seen with an external hard drive. This central location allows the user to back up a full system in addition to file-based backups, using event logs and built-in calendars to schedule automated tasks. Along with the standard recovery operations, you can also use the software to create a bootable rescue CD or, alternatively, an ISO image of the CD to store on the drive for later use.

Seagate also partnered with Acronis Software to include a Try and Decide feature that allows you to download and install new software or open e-mail attachments on the drive in a protected environment, with the added ability to roll back the changes or reimage the drive completely. Starting the management software is simply a matter of hitting a "start" button that turns on a stopwatch and a disk space meter. If you encounter a virus or otherwise harmful malware, hit the "stop" button and the system prompts you to restart and either apply or discard the changes you've made before it locks in. Within the program, "discard" means that your system will revert back to the original image, but only after one restart; the program can't revert after multiple reboots. After playing around with this unique feature, we found that running the program in the background resulted in serious latency issues in system performance, and applying several changes at the end also tried our patience, so we only recommend using this software in at-risk environments where you suspect issues with system security.
