NAS Reviews


The TN-200 was tested with its factory-installed version 1.02 firmware using our standard NAS test process to run tests with RAID 0 and 1 volumes.

Windows File Copy tests in the Benchmarks summary below show read throughput 22% higher than write for RAID 0 (55 v.s 45.1MB/s) and also about 22% faster for RAID 1 (48.8 vs. 40.1 MB/s). Similarly for both read and write tests, RAID 0 held an edge over RAID 1 results. For read operations, RAID 0 was about 12% faster than RAID 1 (55.0 vs. 48.0 MB/s) and for write operations, the margin was about 15% (45.1 vs. 40.1 MB/s).

Intel NASPT File Copy Writes were slightly slower (1.4%) that the Windows File Copy for RAID 0 (44.5 vs 45.1MB/s) but were 37% faster than the Windows File Copy writes for RAID 1 (55.1 vs. 40.1MB/s).

To see how the TN-200 NAS fared against other dual drive NASes, I filtered the results for two-drive devices using a Marvell SoC and then generated charts for File Copy Read and File Copy Write performance. If you use the default sorting, ie, by throughput, the TRENDnet TN-200 doesn't do very well. It ranks 11/16 for File Copy Write Performance and 15/16 for File Copy Read Performance.

For Read, the TN-200's 55.0 MB/s is only about 54% of the top performing $150 Buffalo LS420, which turned in 101.3 MB/s. For Write, the TN-200 measured 45.1 M/s (53%) vs. the top performing $176 Thecus N2310's 85.7 MB/s.

However, since the TN-200 is the cheapest two-bay BYOD NAS on the market, I also sorted the results on price. The results were somewhat interesting. Looking at just file copy performance, you have to spend $140—40% more—before you pass the TN-200's read performance and $149 before you pass the TN-200's write performance.

The table below compares the backup performance of the four sub $150 two bay drive enclosures. Note that only the Buffalo LS421e has a USB 3.0 port. In addition, the TN200 shares relatively poky NTFS performance with the D-Link DNS320; not too surprising since both use the same processor.

USB 3.0 FAT NA 17.5 NA NA
USB 3.0 NTFS NA 20.8 NA NA
Network Backup 18.5 NA 15.5 18.6

For Total NAS rank, which includes all products tested, the TN-200 ranked #47 out of a total of 71 products tested. The one area where the TN-200 excelled was in the Mixed Read/Write tests where it ranked #26 - well above its overall ranking of #47. Relatively low Windows File copy read and write results undoubtedly dragged down the overall ranking.

If you filter the NAS Ranker for two drive devices and SoC-1 class and sort by price, you'll see that the TN-200 has a lower (better) rank than the two next most expensive devices: the #56 ranked $118 D-Link DNS-320L and the #50 ranked $140 Iomega ix2-dl.

Closing Thoughts

For some consumers, a robust set of remote access and personal cloud features that support tight integration with Android / iOS mobile devices is very important. If that describes you, the TN-200 is not for you. As noted earlier, the TN-200's remote access is limited to FTP and WebDAV and it doesn't have dedicated apps for mobile platforms.

But for NAS buyers on a limited budget, the TN-200 could be the perfect product. For only $100 (and sometimes less), you get file sharing that works with all desktop and mobile OSes, media serving via DLNA and iTunes servers, RAID 1 fault tolerance and both attached and rsync network backup. Although it doesn't have chart-topping performance, the TN-200's throughput is more than adequate for simple backup, file sharing and media streaming.

The TN-200's strongest negative, however, is its fan and drive noise, which are definitely audible in a quiet environment. The fan still seems to run even in hibernate mode. But if you can live with or work around this, you'll get a surprisingly good NAS for the money.
