Compared side by side
The Synology DiskStation DS925+ 4-Bay NAS appears in these tables next to models from other brands:
- Best NAS for a photographer with 10 TB of RAW files in Lightroom (2026)
- Can a NAS host a Minecraft server for friends, and which one is best? (2026)
- Which NAS runs Home Assistant OS as a virtual machine with a Zigbee stick? (2026)
Who it's for
Photographers who edit from a local SSD and use the NAS as a managed RAW archive and backup target.
Caveats
- There is no way to add 10GbE: it has two 2.5GbE ports and no PCIe slot.
- Synology's 522/565 MB/s rating uses both ports. One computer on one cable tops out at 312.5 MB/s raw.
- M.2 storage pools and cache need SSDs on Synology's compatibility list.
