Game Data

This test consists of a 96.2 GB game library that is copied as is from an NVMe SSD on the host computer to the NAS and then back from the NAS to the host PC. Everything is timed and converted to transfer speeds in MB/s. In this first real world test, the Asustor Drivestor 2 Gen2 AS1202T is way ahead of the Ugreen NASync DH2300, even when the latter is connected via a USB to 2.5 Gbps Ethernet dongle. Taking into account the much weaker platform the AS1202T is built around, it goes to show that one shouldn't judge a NAS based on its hardware. There's a very slight performance increase using SSDs.

Single Large File

The next test involves copying a single 66.9 GB large file to simulate something like a large video file or a compressed backup file being copied to and from the NAS. Here the AS1202T starts to struggle a bit, especially when it comes to copying the data to the NAS, as the DH2300 is offering almost 60 MB/s better file copying performance. From the NAS the two are very close, but Asustor still falls behind the Ugreen. As you can see, this is also true when using SSDs, so it seems like this might be some kind of caching issue, where there simply isn't enough RAM to handle large chunks of sequential data, but that's just a guess from our side. What struck us as odd was that the performance actually dropped when copying data to the SSDs, even versus the RAID 1 mode, so something odd is going on here for sure.

Photos

Our third and final test consists of 10.6 GB of photos across 4,084 files. This is the test that makes every NAS struggle and the AS1202T is no different. Once again, it's ahead of the DH2300 and we see some good performance improvements when switching to SSDs, particularly when reading data from the NAS, where we see a more than doubling in the read speed.
