Conclusion
Once again we see that Synology’s products are beyond competition in almost every aspect. Most importantly, the developer is improving from model to model, making its products an example of quality.
The DS209+ is impeccable. The developer has corrected the minor flaws in the design of the DS207+ and released a new, improved version of firmware. Coupled with the more advanced electronic stuffing, this makes the DS209+ the flagship of Synology’s NAS range. The only thing that worries us is the big difference in price between the DS209+ and DS207+. We don’t know about the cost of the new processor, but the other improvements, particularly the amount of system memory, do not seem worth the money. We hope the price is high because the model is new and will decline eventually. After all, paying about $500 for a dual-disk NAS is too much for most users. But if you can afford such a purchase, you won’t be disappointed with the DS209+ as it is good in everything from design and functionality to performance.
According to the results of our today's test session, we are glad to award Synology DS209+ with our Editor's Choice title as the best two-disk NAS solution:
