Seagate Backup Plus Slim Review

Seagate Backup Plus Slim
Bottom Line

The Seagate Backup Plus Slim is the slimmest portable hard drive on the market. It's also one of the fastest, according to tests conducted at CNET. User reviews indicate that it's reliable, too, with a low rate of reported drive failures. While most owners find it easy to set up and use, a few report problems getting it to work. Also, it doesn't include security features to block unauthorized use.


Zippy backup speed. No USB 3.0 drive this size -- and very few external drives of any kind -- can beat the speed of the Seagate Backup Plus Slim. In tests at CNET, it was able to read and write files at around 120 Mbps. The drive comes preformatted for Windows (NTFS). CNET editor Dong Ngo says it's also easy to get it to play nice with a Mac, and outlines a couple of approaches. Most users say setup is simple and the included backup software is easy to use.

Lacks password protection. Ngo's biggest concern about the Backup Plus Slim is that, unlike competitors, it doesn't offer a way to password-protect the contents. This means that if you lose the drive, anyone who finds it can access your files. The Seagate's two-year warranty is another weak point, as most other external hard drives are covered for three years. Reliability is nonetheless excellent; The Wirecutter analyzed nearly 250 user reviews at and found that only 3.63 percent of users reported drive failures.


Price is hard to beat. The Backup Plus Slim is competitively priced. We found prices ranging from as low as $55 for the 500-GB version to $120 for 2 TB. (A 4-TB version, called the Backup Plus Fast, costs around $280, but The Wirecutter warns that it has a much higher failure rate than the Slim.) Ngo thinks that Seagate's backup software "adds a lot of value to the drive," especially for Windows users. Overall, he considers it "a great deal."
