This article covers Synology NASキット 6ベイ 拡張可 DS1621+ クアッドコアCPU 4GBメモリ搭載 スタンダードユーザー向け 国内正規代理店品 電話サポート対応品 DiskStation.

Overview

The Synology DS1621+ is a 6-bay network-attached storage (NAS) built for home offices and small businesses requiring reliable data management and advanced virtualization. Powered by an AMD Ryzen quad-core processor with 4GB DDR4 RAM (expandable to 32GB), it delivers up to 110,000 random 4K read IOPS — a 174% improvement over the previous DS1618+. Four 1GbE LAN ports are standard, and an optional 10GbE NIC can be added for bandwidth-intensive workloads. Beyond basic file storage, the DS1621+ supports Virtual Machine Manager (VMM) for running Windows/Linux VMs, Active Backup Suite for centralized backup, and Snapshot Replication for point-in-time data protection. Two built-in M.2 NVMe slots allow SSD caching without occupying drive bays, dramatically accelerating HDD arrays.

Connectivity & Compatibility

Internal Drives: 6x 3.5-inch/2.5-inch SATA HDD/SSD bays. Raw capacity up to 96TB (with 2x DX517 expansion units, up to 256TB). M.2 NVMe Cache: Two 2280 NVMe SSD slots for read/write caching. Networking: 4x 1GbE RJ-45. Optional 10GbE SFP+ or RJ-45 NIC via PCIe slot. External Ports: 3x USB 3.2 Gen1 Type-A, 2x eSATA for expansion units. * OS: Synology DiskStation Manager (DSM) with full app ecosystem. Compatible with Windows, macOS, Linux clients.

Product Info

Released in 2020, the DS1621+ carries a street price around ¥220,000 (drives not included). It comes with a 3-year warranty and phone support for authorized Japanese units. Accessories are minimal: power cable, Ethernet cable, and quick installation guide. The DS1621+ sits at the upper mid-range to high-end tier of the consumer/prosumer NAS market, targeting users who need enterprise-grade features without the enterprise price tag.

Best Use Cases

Data Protection Focused Users: Use Active Backup Suite and Snapshot Replication to back up PCs, servers, and cloud data. Quick recovery from ransomware or hardware failure. Small Office & Remote Work: On-premises file sharing, collaborative document editing, and email server with Synology MailPlus. Privacy control without cloud dependency. Virtualization Enthusiasts: Run Windows or Linux VMs via VMM for testing, development, or running legacy apps. The quad-core CPU and 4GB RAM handle moderate workloads. Media Server Builders: Install Plex or Video Station for 4K transcoding and streaming to multiple devices. M.2 cache helps with metadata and thumbnails. * Not for: Budget-conscious users who only need basic file storage — a 2-bay model like DS220+ is more cost-effective.
