DiskStation DS1821+

High-Performance Storage

The Synology DiskStation DS1821+ is an 8-bay desktop NAS designed for SMBs and enthusiasts, powered by a 2.2GHz AMD Ryzen V1500B quad-core processor with AES-NI encryption and 4GB DDR4 ECC RAM (upgradable to 32GB). It delivers up to 2,323MB/s read and 1,460MB/s write speeds, with 113K 4K random read IOPS, ideal for file sharing, backups, and virtualization. With dual M.2 2280 NVMe SSD slots for caching, it boosts HDD performance by over 20x. Scalable to 18 bays with two DX517 expansion units, it supports up to 300TB in RAID 5 using 16TB drives.

Robust Connectivity and Versatility

Equipped with four 1GbE ports (Link Aggregation/failover support), four USB 3.2 Gen 1 ports, two eSATA ports, and a PCIe 3.0 x8 slot for 10GbE NICs or additional M.2 SSD adapters, the DS1821+ ensures high-speed connectivity. It supports RAID 0, 1, 5, 6, 10, Synology Hybrid, and JBOD, with protocols like SMB, NFS, AFP, FTP, WebDAV, and iSCSI. Synology DSM offers apps for virtualization (VMware, Hyper-V, Citrix), surveillance (up to 40 IP cameras), and cloud syncing with Microsoft 365, Google Workspace, and more.

Data Protection and Ease of Use

The DS1821+ features Synology DSM with Active Backup Suite, Hyper Backup, and Snapshot Replication for robust data protection, including ransomware defense and multi-version backups. File Station simplifies file management with drag-and-drop functionality. Users praise its intuitive UI, quiet 120mm fans (25.2 dB(A)), and hot-swappable bays, though some note Synology’s restrictive HDD compatibility list. A 3-year warranty (extendable to 5 years) and centralized management make it reliable for SOHO/SMB environments.
