Another good reason to build your own NAS.
Synology was a good way to get a decent NAS setup in very little time. I used an entry-level one to make a simple backup machine for my parents and I liked the software so much that I decided to buy one of their NAS units at home as well. Not everything is amazing on the software front, but still it's a very beginner friendly way to start things and can save quite time for advanced users as well. When researching the purchase, I noticed Synology customers have been complaining for a while that the company is focusing their attention away from home users and small businesses (based on the updates and changes to their software ecosystem). I was initially tempted to look into their "local cloud" software to backup family devices, but based on my limited testing and their lack of focus for these apps I have decided to go another route.
The lock-in however is a really big problem, and I'm not talking just about the recent event. The unit I bought has 2x M2 slots that Synology decided can be used for storage only with their branded drives, otherwise can only be used for data caching. I knew about this going in (and researched a workaround) but at the time of my purchase I had hoped they would eventually loosen the restriction, not make it worse. As it stands, this will probably be my first and last purchase from them, which is a pitty because I really enjoyed the combo of convenience and flexibility it came with, extremely easy setup with enough support for more advanced tinkering.
