Is the DS925+ worth it over a cheaper 4-bay NAS?

You pay for the 2.5GbE ports, the Ryzen CPU and DSM's app ecosystem. If you only need simple file sharing on a 1GbE network, a cheaper box does the job; if you want speed, SSD caching and Synology's software, it earns the premium.

How does it compare with the DS923+?

Both are 4-bay units with the same Ryzen V1500B and 2.5GbE pair. The DS925+ is the newer model with updated expansion and DSM support; the DS923+ remains capable and often the better value if you don't need the latest revision.

Can I upgrade the RAM and add SSD cache?

Yes. It ships with 4GB DDR4 and accepts up to 32GB, and the two M.2 NVMe slots are there for read or read-write cache without using drive bays.

Do I need to buy drives separately?

Yes. This is an enclosure only; drives and caddies are sold separately. Check Synology's compatibility list before buying drives, since some third-party models are restricted.

No. It has two 2.5GbE ports, which can be bonded for more throughput. 10GbE requires a compatible network card in the expansion slot.

The enclosure, power supply, Ethernet cable, screws and quick start guide. Drives are not included.
