Best Overall
Synology 4-Bay DiskStation DS925+ (Diskless)
Our verdict: Four bays, mature software and the most room to grow.
The DS925+ is a four-bay diskless NAS running Synology DSM, with directory sync support and multi-bay RAID for redundancy. It is a Plus-tier model eligible for business support and can be expanded as storage needs grow, in the $500 and up bucket. Directory sync lets staff log in with existing company credentials, which cuts account chores.
It ranks first because it combines headroom with the most mature software in this group. The UGREEN beats it on raw processor per dollar, but not on ecosystem or support options.
Buy it for a growing team that needs room, support and a stable platform. The caveats are that drives are sold separately and it sits in the highest price bucket, so skip it if budget matters more than ecosystem.
