Synology's DS223j is an entry-level two-bay NAS built for backups and basic file serving, and its I/O reflects that budget positioning. Networking tops out at a single Gigabit Ethernet port, so real-world transfers are capped around 110MB/s. Two USB 3.2 Gen 1 Type-A ports handle external drives and one-touch backups. There is no HDMI, no M.2 cache slot, and no expansion port — this is a straightforward wired-Ethernet box.
