I don't give 5 stars easily. But this product deserves it. After a disaster of purchasing a WD My Cloud Home Duo, I returned it and purchased the DS218+. I have been VERY happy. Leaving the Amazon order-to-delivery latency aside, the product came well packaged and complete.
Installation - which required that I install two HDDs - was very easy and literally took me 10 minutes and that is because I don't like to read the manual. Once installed, setup was very straightforward once you understand the web-based tool used to configure and manage the device. The DS218+ connected to my home network hub (we use Comcast). I was able to connect to the device from multiple PCs (Win10, Win8, Win7) as well as devices (Android phone and tablet, I haven't tried our iPhone or iPad yet). Once you get the understanding of the user management and permissions approach, it is simple to set up multiple users for the family.
Management - the management interface via their own UI turns out to be excellent. I was put off of yet another UI that I had to learn at first. But I have quickly gotten used to it and the learning curve was pretty quick for the basics. But I have also noticed there is a lot of power in the UI as well to really tailor your system to your needs. That will take some time to digest. Best thing about the UI are the "Stations". They have them for videos, photos and music. Get tools to manage the huge libraries of each that I have collected over the years. The Video Station is really nice in that it ties to the web to get add'l info on the movies along with graphics, etc. It effectively looks like Netflix for your movie library.
Usage - I am primarily doing two things with this device: 1) accessing my photos/videos/music remotely and 2) syncing my business files from my work and from my personal company. As for the remote file access - works really well. There are DS apps available for Android (and I assume iStuff). Each of the apps are clean and pretty easy to use. the DS Video app gives you that same Netflix look and feel I mentioned earlier. The music and photo apps work very nice - they could have a few more features for sorting, but I assume those will come with time. As for the file sync, that works VERY nicely. I have installed the Cloud Drive app on my PCs. Once I figured out how the software worked I have been able to get very detailed about which files to sync. It is now working like a charm and does not seem to impact performance of my PCs. I haven't set up any backup arrangement yet - we will see how that goes.
Overall, I am VERY high on this product. Looks great. Very quiet (unlike the WD product). Easy to manage.

DS218+ Broke in the most important moment
I purchased this Synology NAS after thorough research across forums, blogs, and YouTube, aiming for a high-performing, reliable solution for data storage. I initially weighed Synology against QNAP but ultimately went with Synology due to its reputation, extensive experience, and robust ecosystem of tools and applications.Upon arrival, the NAS impressed me with its solid build quality and worked flawlessly for the first two years. The interface was intuitive and user-friendly, and I installed two new Seagate IronWolf 2TB drives. My main uses were file backups and managing home security cameras through the Surveillance app. The "Synology Photos" app was also a highlight, providing a Google Photos-like experience without subscription fees or data mining. I found Synology’s DNS service particularly convenient as well.However, while on a long trip, I was notified that the NAS wouldn’t power on. My family managed to restart it after several attempts, but shortly after, the hard drive showed signs of degradation. Despite replacing the disks and the power supply, the issue persisted, leaving me anxious about the safety of my files—especially photos and documents from my travels. I was also forced to look into alternative backup solutions while away.After returning, I took the NAS to a data recovery service, where they diagnosed a logical failure likely caused by a motherboard issue. Recovery costs were estimated in the thousands. Unfortunately, with the warranty expired, I couldn’t get support from Synology.In summary, this NAS might be sufficient for short-term use or storing non-essential files. But if you need a reliable, long-term solution for critical data, I’d suggest exploring other options.
