This article covers 【NASキット】Synology RackStation RS822+ [4ベイ.

Overview

The Synology RackStation RS822+ is a 4-bay 1U rackmount NAS kit designed for small to medium businesses and prosumers. It is powered by an AMD Ryzen V1500 quad-core 2.2GHz processor and comes with 2GB of DDR4 ECC memory (expandable up to 32GB). This unit supports hot-swappable SATA drives and can be expanded with up to two RX418 expansion units, bringing the total to 12 bays. As a barebone kit, it ships without any hard drives or SSDs, allowing you to choose the exact storage configuration for your needs. The RS822+ runs Synology's DiskStation Manager (DSM), offering a comprehensive suite of applications for file sharing, backup, virtualization, and surveillance.

Connectivity & Compatibility

The RS822+ provides two Gigabit Ethernet ports (RJ-45) on the rear panel, along with two USB 3.2 Gen 1 ports and one eSATA port for external storage or UPS connectivity. An internal PCIe Gen3 x8 slot allows you to add a 10GbE network card or an M.2 NVMe SSD cache card to boost performance. It supports 3.5-inch and 2.5-inch SATA HDDs and SSDs, with a maximum internal raw capacity of 72TB (using 4x 18TB drives). RAID levels 0, 1, 5, 6, 10, and Synology Hybrid RAID (SHR) are supported. The unit is compatible with Synology expansion units (RX418) via the eSATA port, enabling seamless capacity growth.

Product Info

Released in 2022, the Synology RackStation RS822+ sits in the mid-range segment of Synology's rackmount NAS lineup. It is priced around ¥190,000 (tax excluded) in Japan, positioning it as a cost-effective solution for businesses that need reliable rack-mounted storage without the high cost of enterprise-grade models. The standard warranty is 3 years, with optional extended coverage. The package includes a power cord, two Ethernet cables, a quick installation guide, and drive mounting screws. The chassis is made of alloy steel and is designed for 1U rack installation (rail kit sold separately).

Best Use Cases

Small business file server: Ideal for companies needing centralized file storage with user permissions, snapshot protection, and remote access. The RS822+ can handle up to 20-30 concurrent users for typical office workloads. Home lab virtualization: With support for iSCSI and NFS, this NAS can serve as a storage backend for VMware or Hyper-V environments. The PCIe slot allows adding 10GbE for faster VM traffic. * Backup target for multiple PCs: DSM's Active Backup for Business can back up Windows, macOS, and Linux clients, as well as Hyper-V/VMware VMs, directly to the NAS. The 4-bay configuration provides enough capacity for several TB of backups. However, if you need more than 72TB of raw storage or require dual power supplies, consider stepping up to the RS1221+ or RS2423RP+. For users without a rack, the tower-style DS1522+ offers similar specs at a lower price.
