The Synology DS1825+ is an 8-bay desktop NAS designed to provide high capacity and flexibility in a compact form. It comes with dual 2.5 GbE ports built in and supports PCIe expansion for 10/25 GbE networking, giving it the ability to scale with more demanding network environments. The unit also features two M.2 NVMe slots (for SSD cache or SSD pools) and supports expansion via two DX525 units—boosting total raw bay capacity up to 18 drives.
Under the hood, it is powered by an AMD Ryzen V1500B quad-core 2.2 GHz CPU and ships with 8 GB of ECC DDR4 memory (expandable to 32 GB). It supports both 3.5″ and 2.5″ SATA drives and offers broad RAID options including SHR, RAID 5/6/10, JBOD, and more.
On the software side, the DS1825+ runs Synology’s DiskStation Manager (DSM), which provides tools for file sharing/syncing, backup, virtualization, cloud integration, snapshots, and surveillance deployment. It’s aimed at users who want a full-featured NAS with strong software and future-proof networking expansion.
