Promise Pegasus R4 vs Seagate Backup Plus Slim STHN (2019)

Analysis:

The Promise Pegasus R4 makes for a mediocre NAS and should be avoided by the majority of people.

In the case of the Seagate Backup Plus Slim STHN 1TB, however, we were unable to find enough data to come to any meaningful conclusions.

There are considerably better alternatives that can be found for around $1,800 and $110 available on the market.

If you're still interested in reading more about the Promise Pegasus R4, however, here's a quick summary of what we know about it:

The Promise Pegasus R4 managed to earn a spot in roundups from two sources that are known for their trustworthy review methodology - PCmag and CNET - but fell short of making it to the top of their lists.

As for the Seagate Backup Plus Slim STHN 1TB - it was really well-received by reviewers at Wirecutter, a great source that's known for conducting high-quality in-depth testing. It performed great in its "The Best Tech and Apps for Your Home Office" roundup and was named its "Top Pick", which, on its own, makes it a product that warrants a closer look.

We conducted an analysis of all of the review data that we could find on these two products. First, we focused on sources that tested and rated both of them, like CNET, and learned that they all showed a preference for the Seagate Backup Plus Slim STHN 1TB.

Then we took a look at the highest review scores that these two NAS Devices received. We found that the Promise Pegasus R4 managed to earn a rating of 8 from PCmag, whereas the Seagate Backup Plus Slim STHN 1TB got its highest, 9, score from reviewers at kitguru.net.

Lastly, we averaged out all of the reviews scores that we could find on these two products and compared them to other NAS Devices on the market. We learned that both of them performed far better than most of their competitors - the overall review average earned by NAS Devices being 7.4 out of 10, whereas the Promise Pegasus R4 and Seagate Backup Plus Slim STHN 1TB managed averages of 7.8 and 8.0 points, respectively.

Due to the difference in their prices, however, it's important to keep in mind that a direct Promise Pegasus R4 vs. Seagate Backup Plus Slim STHN 1TB 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.
