The F2-220 runs a new, revamped version 3 of TOS (TerraMaster Operating System) The new user interface features a desktop interface supporting multiple resizeable windows - much like you see on products from other manufacturers. The image below shows the TerraMaster landing page with three windows open. Across the top of the screen, note the icons for the open apps. These icons let you easily re-open a minimized window. In the lower right corner, there's a system performance widget you can minimize. This widget is common across various updated NASes that I've reviewed recently.

The main quirk you'll note is the "desktop" icons require two clicks to open. All icons on other screens open with one click.
TOS3 has a decent set of add-in applications shown below. The built-in web-based File Manager is pretty good, too and supports a full set of file operations.

TerraMaster has an online emulator that will let you experiment with most features of TOS 3. The emulator even allowed me to create a standard (non-privileged) user, log out, and log back in as the newly-created user so see how the interface looks to a non-admin client.
The short gallery below shows various features of the TOS 3 operating system.
TerraMaster Firmware version 3.0.24 was loaded onto the F2-220 and performance tests were run using the Revision 5 NAS test process. All tests were run using Western Digital Red 1 TB drives (WD10EFRX) (x2 SNB supplied).
Many NASes have enough processing power to max out our single Gigabit client file copy read and write tests at the maximum of about 109-110 MB/s. Since the three NASes we're comparing are entry level, I didn't really expect that any of them would max out those tests. However, both the ZyXEL and ASUSTOR had throughput above 100 MB/s for RAID 0 and RAID 1 file copy read and write tests, with the exception of RAID 1 File copy read for the AS1002T. For the Noontec TerraMaster F2-220, File Copy Read results were below 100 MB/s at 90 MB/s for RAID 0 and only 83 MB/s for RAID 1. For all of the NASPT tests, the F2-220 scored either lower or significantly lower than either of the other two NASes.
The one bright performance spot for the F2-220 was backup. It smoked the competition on the attached USB 2.0 and USB 3.0 backup tests for all three file systems tested and on the rsync network backup tests. It also outperformed the other two NASes for iSCSI write but finished behind for iSCSI Read.
The composite image below shows the detailed benchmark summaries for the three products being compared.

Turning to the NAS Ranker, the image below shows RAID 1 devices sorted by ascending price. I've included the next two more expensive NASes in addition to the ones compared in this review. As you can see, the Noontec TerraMaster F2-220 has a Total NAS ranking of #17. Both of the other two NASes compared in this review have a better (lower) Total NAS ranking and a lower price.

Looking at the category summaries for Ranker Performance, the TerraMaster F2-220 had category wins only for backup and iSCSI. It lagged far behind the #11 ranked ASUSTOR AS1002T in all other categories. Even the $128 ZyXEL outperformed the F2-220 in the top four categories.

The Noontec TerraMaster F2-220 has a difficult marketing story. It's priced significantly more than the ZyXEL NAS326, yet ranks only one step lower. For approximately the same amount of money as the TerraMaster, the ASUSTOR AS1002T offers significantly better performance in the top four categories (Write, Read, Mixed Read Write, and Video) that are most likely to be important to NAS buyers.
If you're on a tight budget, buy the ZyXEL NAS326. If your budget tops out just south of $200, the ASUSTOR AS1002T is the clear choice. But if you can stretch your NAS budget to $250 or so, you can move way up the performance charts to the more fully-featured #4 ranked Synology DS216. In any of these scenarios, I don't see that the Noontec TerraMaster F2-220 offers a value proposition that would attract many well-informed buyers.
