Conclusion
Notwithstanding its good performance, the tested NAS falls short of my expectations. Besides high speed, the only good thing about the TS-S402 is the efficient cooling of HDDs, but it is achieved at a high level of noise. In its other parameters this model cannot match its opponents and its price of about $180 looks somewhat too high in comparison. Summing it up, I would not recommend you to invest your money into the TS-S402 if you need a really functional device. It would be better to add some more and buy an inexpensive model from Synology or QNAP. The price/performance ratio of the TS-S402 may be acceptable if you need just a very basic NAS.
