I was spending about $100 a year for cloud storage and wasn't happy about the features with that service. I also wanted a better solution for sharing my personal content with friends and family. And, finally my home has become increasingly "smart" with many devices that are capable of connecting to my personal network and utilizing data stored there. For these reasons I decided to make the investment in my own server and chose this Synology device. I have to say it has provided everything I was looking for and a little more. I started with two 8TB IronWolf drives running a mirror backup, so I end up with a little less than 8TB of usable data. I'm pleased that I always have the option of adding more drives if the need arises. Below I'll list some of the pros and cons as I see them.
Pros Easy to set up Lower cost to start, with expansion if needed Easy access from anywhere So far, reliable From what I can tell, great support both corporate and community Great apps
Cons Sometimes not registered on my network, but always accessible through the web interface Loud, the drives can be pretty noisy, but I just tuned them out over time Total package is expensive, but less than others
I used YouTube to help with setup and to get to know the device and its functions. So, it was easy to get going. Synology has several apps available to use your data, like DSAudio to stream your music and DSFile to see all, data, and even a media streaming app for video. I put VLC media player on my computers and Android TVs for the video part and it works perfectly. I created a limited user account for friends and family to access the content I share and sent the login info to them. They can now login at any time to see our pics and videos. The freedom this system allows is beyond what I was expecting and very welcomed. I recommend it to everyone.
I'ts ok but network speeds are slow, all my computers large file transfer speeds using rsync run about 110MB/s, this device is about 45MB/s. SMB runs about 85MB/s. The Web interface is pretty good. I just wish network speeds were faster. If I had to do it over again I would of built a NAS my self for faster speeds. If this device dies I won't replace it. I installed PLEX on this NAS which runs pretty well. The disks are loud which can be annoying. The setup did not allow me to pick the RAID configuration I wanted. It used "Synology Hybrid RAID (SHR) (With data protection for 1-drive fault tolerance)" with the two 12TB and two 16TB drives it created a 38.41 TB Volume formatted with Btrfs.
For a basic NAS, this works great (as long as you don't need encryption of course, synology still doesn't support real encryption), and I was able to migrate easily from my old synology DS216j.
However, I bought the DS418 specifically because synology claimed it supports BTRFS.
It turns out only in the most useless, minimalist way possible. It is completely incapable of using BTRFS' native capabilities to mirror and correct data, and instead uses a frankenstein's monster of hacked up dmraid/btrfs/proprietary nonsense that I wouldn't trust anywhere near important data, and worse, they bury this information very deeply. Worse, there's no way to force it to use safer mirroring instead of risky RAID 5/6 under the hood.
