Seagate Backup Plus Slim STHN (2019) vs Western Digital Black D10 Portable Drive

Analysis:

The Seagate Backup Plus Slim STHN 1TB is a great Portable HDD for its $64 asking price.

The Western Digital Black D10 12TB, however, is merely passable at its $357 price point. If you're considering buying a Portable HDD in the $450 range, you might want to check out some of its competitors.

The Seagate Backup Plus Slim STHN 1TB has impressed reviewers from two sources that are among the most highly trusted on the internet, namely Wirecutter (NYTimes) and Laptop Mag. It did great in their objective hands-on roundups - it earned the "Top Pick" and "The best budget-friendly external HDD" awards from Wirecutter (NYTimes) and Laptop Mag, respectively. That's high praise from such reputable sources.

Moving on to the Western Digital Black D10 12TB: it has done really well in a number of roundups done by sources that perform objective and reliable testing, including creativebloq.com, Techradar, and Android Central - it won the "A great high-capacity choice" title from creativebloq.com, "Pricey, but great speed and features" from Techradar, and "Ranked 3 out of 12" from Android Central. That points towards it being a cut above most of its competitors.

We couldn't find any sources that tested both of these Portable HDD, so we only analyzed how they performed in reviews from different sites.

We first examined which sources rated each of these best and found that the Seagate Backup Plus Slim STHN 1TB got its highest, 9, rating from kitguru.net, while the Western Digital Black D10 12TB earned its best, 10, score from T3.

Lastly, we averaged out all of the reviews scores that we could find on these two products and compared them to other Portable HDD on the market. We learned that both of them performed far better than most of their competitors - the overall review average earned by Portable HDD being 7.3 out of 10, whereas the Seagate Backup Plus Slim STHN 1TB and Western Digital Black D10 12TB managed averages of 8.1 and 9.5 points, respectively.

Due to the difference in their prices, however, it's important to keep in mind that a direct Seagate Backup Plus Slim STHN 1TB vs. Western Digital Black D10 12TB comparison might not be entirely fair - some sources don't take value for money into account when assigning their scores and therefore have a tendency to rate more premium products better.
