The Synology RS4021xs+ 16-bay rackmount NAS server is a 3U storage solution for small and medium-sized businesses. It features 16 drive bays that support 3.5-inch SATA HDDs or 2.5-inch SATA SSDs. An 8-core Intel Xeon processor manages data requests. This configuration provides centralized data management for multi-user workloads. Storage capacity can be scaled by populating the available slots. The system uses error-correcting code (ECC) memory to maintain data integrity and prevent system crashes during high-volume operations.
The device includes six RJ45 Ethernet ports for flexible connectivity. Power consumption is approximately 145.79 W during typical operation. Two USB 3.2 Gen 1 ports are provided for connecting external peripherals. RAID 5 and RAID 6 configurations provide storage-level protection against drive failure. The black chassis fits standard server cabinets and has a depth of 656.5 mm. Integrated backup tools support centralized data protection. Reset and power switches are located on the front panel of the 3U enclosure.
