The Synology DS725+ in depth

Small footprint, Plus-series performance

At 166 x 106 x 223 mm and 1.51 kg, the DS725+ is a compact desktop unit that runs a Ryzen R1600 with 4 GB of ECC memory that can grow to 32 GB. A 2.5GbE port gives faster-than-gigabit transfers, and Synology rates it at up to 276/224 MB/s sequential read/write in its own testing.

Start with two drives, grow to seven

Two hot-swappable SATA bays sit alongside two M.2 NVMe slots for SSD cache or a separate storage pool. When you outgrow two bays, a DX525 expansion unit connects over USB Type-C to support up to seven drives and unlock RAID 5.

Everything DSM offers

DSM provides file sharing and sync with Synology Drive, photo management with Synology Photos, collaboration tools, and licence-free backup with Active Backup Suite, Hyper Backup and Snapshot Replication. Surveillance Station supports up to 40 x 1080p cameras with 2 licences included.
