Is the DS725+ fast enough for 2.5GbE transfers?

Synology rates it at about 276 MB/s sequential read and 224 MB/s write, which is enough to use most of a 2.5GbE link. Real speeds depend on drives, RAID type and network gear.

How much storage can it hold?

Two internal bays plus a Synology expansion unit take it to a rated 140 TB of raw capacity. The M.2 slots are for cache, not for storage pools.

Can I upgrade the memory?

It ships with 4 GB of DDR4 SODIMM memory. Synology lists the memory as upgradable, which helps when running many packages or virtual machines.

Does it work as a surveillance recorder?

Yes. Synology says it can manage up to 40 IP cameras, though camera licenses beyond the bundled ones are separate.

How does it compare with the DS723+?

Both are two-bay units with 2.5GbE and two M.2 slots. The DS725+ uses an AMD R1600, while the DS723+ uses a Ryzen R1600; check the CPU and memory ceiling that matter for your workload.

The unit itself, an AC adapter, a power cord, an Ethernet cable, drive screws and the quick installation guide. Drives are not included.

Our take on the Synology DiskStation DS725+ SAN/NAS Storage System

The DS725+ is a two-bay NAS built around an AMD R1600 dual-core CPU with 4 GB of DDR4 memory and a built-in 2.5GbE port. It takes two 3.5"/2.5" SATA drives plus two M.2 NVMe slots for cache, and Synology rates it at about 276/224 MB/s sequential read/write. It suits home users and small offices that want fast file sharing, endpoint backup, camera surveillance and site sync from one box. Against two-bay rivals it stands out for the 2.5GbE port and NVMe cache slots; the trade-off is a modest 4 GB of RAM and only one USB port.
