Score: 74/100Rankings
A secure, rack-mountable 4-bay NAS with built-in drives, 2.5 GbE networking and strong encryption, aimed at small offices and home labs, but constrained by modest memory and lack of performance-enhancing features.

The LinkStation SoHo 220 is an entry-level 2-bay NAS offering 8 TB of pre-installed storage with basic RAID options. It excels in simplicity and low power draw but falls short on performance, security, and modern connectivity features.
