Final Thoughts

The Pegasus2 R2+ is the first product I have ever used from Promise Technology. I have used many other Thunderbolt products from WD, LaCie and even Drobo, but the Pegasus2 is different. The build quality of this solution is damn near flawless, but I don't care for glossy panels and the things that come along with it i.e. fingerprints, dust, scratches.

 

 

The R2+ has just a sliver of piano black gloss with the power button tucked away within. Adding to the R2+ is the metal chassis and large cooling fan and as you may have noticed in our up close look at the software it keeps tabs on both drives and the speed of the fan to maintain operating temperatures. I honestly haven't seen a Thunderbolt RAID solution with software as in depth and easy to use as the R2+.

 

The performance of the R2+ was pretty good but not stellar, but this is a hard drive based solution and only two bays at that. I was pleased to see Promise using Toshiba hard drives in their R2+ as they are certainly some of the quickest drives on the current market. In our testing, we found the RAID 0 array to touch upwards of 350 MB/s in DST while the RAID 1 array hovered around 190 MB/s. In AJASystemTest, the RAID 0 array scaled quite well with each increase in workload from 524 MB/s in 720p to 605 MB/s in 4K.

 

As far as the pods were concerned, I was delighted to see Promise enabled UHS-II support with their SD/CF solution and that was quite evident as our SanDisk Extreme Pro touched 233 MB/s read and 131 MB/s write. SSD performance was also quite good topping out at 465 MB/s read and 366 MB/s. write.

 

Overall, the Promise Pegasus2 R2+ is an extremely flexible storage solution for prosumers and in its 6TB configuration is an incredibly well-built hardware RAID solution for those wanting a dual connectivity Thunderbolt 2 / USB 3.0 device that currently carries an MSRP of $699.99 with two-year warranty.
