The catch

The CPU and 2GB of RAM are modest for the price; heavy Docker or many users want the UGREEN DXP4800 Plus. Check Synology’s drive compatibility list before buying drives.

4 bay in one line

The sweet spot: four drives in RAID 5 or SHR lose only one drive to protection, and you can grow the pool later. Pick this if your library will outgrow one drive.
