Synology DS920+ 4-Bay 1GbE NAS Testing
We have a fairly good comparison set picked out for the DS920+ testing:
Intel NAS Performance Toolkit
The Intel NAS Performance Toolkit (Intel NASPT) is a file system exerciser and analysis tool designed to enable performance comparisons between network-attached storage (NAS) devices.
RAID 5 Performance Tests
We ran our tests with a RAID 5 configuration, and most users would use this with a 4x HDD configuration. The NVMe SSD cache was also used with 2x 1TB NVMe SSDs. Smaller capacity NVMe SSD would also work as well; we simply had 1TB drives and used those. We would not expect there to be a great deal of difference with our tests using smaller capacity SSDs here.
In these tests, we see the Synology DS920+ 4-Bay 1GbE NAS compared to the array of 4-bay NAS’s. What we note is the DS920+ is consistent in performance, generally hitting the top-performing 4-bay NAS with few exceptions. With 1GbE networks, the DS920+ easily saturates the network connecting with or without cache SSDs. Also, to note, our NAS selection spans many years of reviews, there is a wide range of different configurations, including CPUs and RAM load-outs.
One can also make the argument that even older 4-Bay NAS’s perform at acceptable levels when compared to new modern units. In the case of the DS920+ upgrading from an older 4-Bay NAS does not get you much in terms of performance. If these older 4-bay units have been in service for many years, it may be worthwhile to upgrade just to be on newer hardware as electronics degrade over time.
What is likely is that if the DS920+ had a 2.5GbE port it would have been significantly faster than its competition on several of these results.
Let us move on to our RAID 5 Encrypted Performance Tests and finish with our final thoughts.
