This article covers Synology NASキット 8ベイ DS1819+ 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 DiskStation DS1819+ is an 8-bay mid-range NAS designed for home and small business users. Powered by a quad-core Intel Atom C3538 processor clocked at 2.1GHz and equipped with 4GB of DDR4 memory (expandable to 32GB), it delivers reliable performance for file sharing, backup, and media streaming. The built-in AES-NI hardware encryption engine ensures fast encrypted data transfers without significant performance loss. With eight drive bays supporting both 3.5-inch and 2.5-inch SATA HDDs/SSDs, the DS1819+ can accommodate large storage pools — easily exceeding 80TB with today's high-capacity drives. Dual Gigabit LAN ports come standard, and the PCIe 3.0 x8 slot allows you to add a 10GbE network card or an M.2 SSD cache adapter (M2D18) for a significant speed boost.

Product Info

The Synology DiskStation DS1819+ was released in late 2018 and remains a solid mid-range choice in Synology's lineup. It sits above entry-level 4-bay models and below the high-end 12-bay or rackmount units. Standard memory is 4GB, but you can upgrade to 32GB via two SO-DIMM slots. The warranty is typically 3 years (Japanese authorized models include phone support). The package includes a power cable, LAN cable, quick installation guide, and screws. It is still widely available through retailers like Japan.

Best Use Cases

Small office file sharing and backup: With 8 bays, you can build a large-capacity storage pool and handle multiple concurrent users. However, for teams larger than 10 people, consider the higher-end DS1821+ for better CPU performance. Home media server: Ideal for running Plex or Video Station to stream movies and music across devices. Note that the Atom C3538 has limited transcoding capability — if you need 4K transcoding, look at models with an integrated GPU. * Data protection and backup: Use Btrfs snapshots and Hyper Backup for robust data protection. Supports RAID 5/6/10 for redundancy. The fans can be a bit audible under load, so place it away from quiet living areas if noise is a concern.
