The Synology DiskStation DS1821+ is an eight-bay desktop NAS for centralized data management in homes and small offices. This model comes preconfigured with 128 TB of storage across eight 16 TB hard drives. An AMD Ryzen Embedded V1500B quad-core processor (2.2 GHz) provides the processing power for file services and multitasking. It supports RAID 5, 6, and 10 to ensure data redundancy. The unit runs on the DiskStation Manager platform, which manages network file sharing via SMB, NFS, and AFP. ECC DDR4 memory prevents bit-flip errors to maintain data integrity during operation.
The system connects via four integrated Gigabit Ethernet ports that support link aggregation and failover. Hardware capabilities can be expanded using a PCIe Gen 3 x8 slot, which accommodates network interface cards. Two M.2 slots are available for NVMe SSD caching or storage volumes without occupying the primary drive bays. Four USB 3.2 Gen 1 ports and two eSATA connections provide interfaces for external backup or expansion units. Dual 120 mm fans cool the system, maintaining a noise level of 22.2 dB during standard use. The drive bays are hot-swappable for maintenance while the system remains powered on. The 250 W power supply is integrated into the chassis, removing the need for external adapters.
Key Features:- AMD Ryzen Embedded V1500B quad-core processor: 2.2 GHz clock speed and eight threads for multi-user workloads.
- 4 GB DDR4 ECC memory: includes error-correcting code to maintain data consistency; expandable up to 32 GB.
- Four Gigabit Ethernet ports: support network throughput optimization through link aggregation or redundancy via failover.
- Dual M.2 2280 slots: for NVMe SSD caching or storage volumes to improve random I/O performance.
- PCIe Gen 3 x8 expansion slot: supports upgrades to 10GbE or 25GbE network adapters.
- BTRFS and EXT4 file system support: enables data protection features such as snapshots and folder-level quotas.
- Lockable drive bays: for secure disk replacement with minimal downtime.
