2026 verdict
Eight bays each, so which Synology earns the desk space?
For most home and small office users the Synology DS1825+ is the smarter eight-bay NAS: it is the lower priced, draws 60.1 W against 87.93 W and lists a 3 year warranty. It also supports Synology Hybrid RAID, which the Synology DS1823xs+ does not. The Synology DS1823xs+ is the performance model, with a Ryzen V1780B, a built-in 10 GbE port and two 1 GbE ports where the DS1825+ has two 2.5 GbE ports. Both share the same chassis, eight hot-swappable bays, two M.2 slots, 8 GB of ECC memory and no hardware transcoding. Choose the Synology DS1825+ for capacity and running cost, and the Synology DS1823xs+ when 10 GbE speed to a workstation is the point.

What the differences mean
Network ports
The Synology DS1823xs+ has one built-in 10 GbE port and two 1 GbE ports. The Synology DS1825+ has two 2.5 GbE ports and no 10 GbE, though it has a PCIe slot where a 10 GbE card can go. For editing video over the network, the built-in 10 GbE is what matters.
Processor
The Synology DS1823xs+ uses a Ryzen V1780B and the Synology DS1825+ a Ryzen V1500B, both with 4 cores. The faster chip helps with virtual machines and heavy Docker workloads, and matters little for plain file serving and backups.
Power and noise
The Synology DS1823xs+ draws 87.93 W under access against 60.1 W for the Synology DS1825+, a gap that shows on an always-on power bill. Noise is 23.6 and 23.8 dB, so neither is quieter in practice.
RAID options
The Synology DS1825+ lists Synology Hybrid RAID, which lets you mix drive sizes. The Synology DS1823xs+ does not list it, so it suits buyers who plan matched drives and standard RAID 5 or 6.
Warranty
The Synology DS1825+ lists a 3 year warranty. The Synology DS1823xs+ lists none in its data, so check the terms before buying.
Which one to buy if
- you want the most storage per dollar and a lower power bill
The Synology DS1825+ has the same eight bays and expansion as the DS1823xs+ but draws 60.1 W instead of 87.93 W.
- you want to mix different drive sizes in one volume
It lists Synology Hybrid RAID, which the Synology DS1823xs+ does not.
- you move large files over a 10 GbE network and want it built in
The Synology DS1823xs+ has a 10 GbE port on the board, so no card is needed.
- you run several virtual machines or heavy containers
Its Ryzen V1780B is the faster processor of the two, and it accepts the same 32 GB of ECC memory.
