Synology has many models targeted at different categories of users. And, as in the case of Apple, it is always preferable to purchase a top model in the selected category. Linux servers of this company are focused on working mainly with Apple products, although they work fine in Microsoft Active Directory.
I have long been using these servers for myself, private customers and in my corporate network. And I can say that they are among the best on the market.
And according to the link given by you, the low ratings are only for 10% - they simply do not know how to cook or out of luck.
Consider that the server is sold without disks. And you need to buy disks specialized, fast and for a RAID organization (with a spare one in case of failure).
Synology has a list of recommended disk models and recommended UPS models.
When initializing, choose regular RAID-10 - this will ensure fast writing compared to other types of RAID and sufficient protection.
I now have (black Hitachi (HGST 7200) 4TB )*4 and (WD40EFRX 4TB)*4, which gives 8TB of working capacity per server with four compartments.
I connect the home server with two Ethernet wires in Link Aggregation mode to an
HP 8 port hub.
