The TerraMaster F5-422 is easily the most well-equipped platform I've seen from them over the years. The design, while not as clean-cut as the QNAP and ASUSTOR appliances, does offer legit build quality with aluminum exterior and steel internals. The drive trays are ample and plastic to reduce vibration but can be finicky when inserting them into the chassis, again no drive locks, which should be a must on SMB platforms.
The performance was abysmal in most cases in my testing. Even using SSDs and 5GBe produces results that were at most times no better than a 1GBe appliance could offer. That said, it did seem to do quite well in video playback for some reason, along with Database and File Server workloads. I do think TerraMaster can resolve these issues in time, likely with improvements and optimizations within their OS.
The TNAS platform has gone relatively unchanged but does support the most wanted/needed features, including Storage Pools, BTRFS file system for snapshots, AES hardware encryption, and a small set of applications like Plex, Dropbox, and WordPress. It also has come a long way in supporting simple remote access with its TNAS.online feature.
Overall, the F5-422 needs work, but if you are one that will move to 10Gbe in the future and can live through reduced performance now, this solution could very well be the best bang for your buck. MSRP of the F5-422 comes in at $599.99 with a one-year warranty.

The Bottom Line
The F5-422 needs work, but could easily end up being one of the best 10Gbe appliances for those on a budget after some performance issues have been solved.
