Synology DiskStation DS925+ - 4-bay NAS server, Black

The Synology DiskStation DS925+ is a 4-bay NAS for home offices and small business environments. It runs on the Synology DiskStation Manager (DSM) operating system, which includes tools for automated backups and snapshots. The unit is powered by an AMD Ryzen V1500B quad-core 2.2 GHz processor and 4 GB of DDR4 ECC memory. Four hot-swappable drive bays support 3.5-inch hard drives or 2.5-inch solid-state drives via a SATA interface. Networking is handled by two 2.5GbE Ethernet ports, which support link aggregation and failover for improved throughput and reliability. Storage can be configured using RAID 5, RAID 6, or Synology Hybrid RAID to balance capacity and data redundancy.

Internal expansion includes two M.2 2280 NVMe slots for SSD caching or high-speed storage pools. Two 92 mm fans provide active cooling to maintain stable temperatures during intensive tasks. System memory can be upgraded to a maximum of 32 GB via two SO-DIMM slots to accommodate memory-intensive workloads. Two USB 3.2 Gen 1 ports are available for external storage or peripherals. Support for Btrfs and ext4 file systems enables advanced data protection, such as point-in-time recovery. The web-based administration interface is accessible through standard browsers, enabling straightforward remote management. The NAS also supports common network protocols, including SMB, NFS, and iSCSI, for integration into mixed-platform environments.
