Promise Pegasus R4 vs iStorage diskAshur Pro2 Portable HDD

Analysis:

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

In the case of the iStorage diskAshur Pro2 3TB, 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 $900 and $270 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 iStorage diskAshur Pro2 3TB, it wasn't able to earn a top spot in any roundups from trusted sources that conduct their own hands-on testing. Nevertheless, it managed to impress reviewers at Techradar, dongknows.com, and Macworld enough to make it onto their respective shortlists.

We couldn't find any sources that tested both of these NAS Devices, 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 Promise Pegasus R4 got its highest, 8, rating from PCmag, while the iStorage diskAshur Pro2 3TB earned its best, 9, score from techaeris.com.

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 iStorage diskAshur Pro2 3TB managed averages of 7.8 and 8.4 points, respectively.

Due to the difference in their prices, however, it's important to keep in mind that a direct Promise Pegasus R4 vs. iStorage diskAshur Pro2 3TB 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.
