The Synology DiskStation DS1821+ is an 8-bay network-attached storage (NAS) system designed for centralised file management and data protection. This tower-format device uses an AMD Ryzen Embedded V1500B quad-core processor at 2.2 GHz to manage multi-user workloads. Users can install up to eight 2.5-inch or 3.5-inch SATA hard drives or solid-state drives. It supports various RAID configurations, including RAID 0, 1, 5, 6, 10, and JBOD, for flexible data redundancy. Integrated hot-swap drive bays allow for disk replacement without interrupting system operation. The unit supports a maximum internal storage capacity of 108 TB.
The hardware includes 4 GB of DDR4 ECC memory, which is expandable to 32 GB via two SO-DIMM slots. Networking is handled by four Gigabit Ethernet ports that support link aggregation for increased throughput and failover protection. For local data transfers and expansion, the chassis features four USB 3.2 Gen 1 ports and two eSATA ports. Data integrity is managed through the DiskStation Manager operating system, which provides support for the Btrfs file system and snapshots. Cooling is handled by two 120 mm fans that maintain a noise level of 22.2 dB during operation. A single PCIe Gen 3 x8 slot allows for the installation of additional network interface cards or storage controllers.
Key Features:- 8-bay SATA chassis supporting both 2.5-inch and 3.5-inch hard drives and solid-state drives.
- Two dedicated M.2 slots for NVMe cache or high-speed storage volumes.
- AMD Ryzen Embedded V1500B quad-core CPU at 2.2 GHz for multi-tasking performance.
- 4 GB of DDR4 ECC RAM, which detects and corrects data errors to improve system reliability.
- Four Gigabit RJ-45 ports with link aggregation support to enhance network bandwidth.
- Support for multiple RAID levels, including RAID 5, 6, and 10, for hardware-level data redundancy.
- Active cooling system with two 120 mm fans rated at a 22.2 dB noise level.
- Expandable memory architecture supporting up to 32 GB of RAM.
