5 Things to Know About the Synology DS923+ Expansion Formula
Regarding the Synology: 1. The DS923+ starts with 4 internal drive bays. This is the same base configuration as the previous DS920+ model.
You can expand to 9 total bays with one DX517 expansion unit. The DX517 adds 5 more bays, giving you a straightforward upgrade path.
The expansion formula avoids a full chassis migration. You do not need to buy a larger NAS or move your drives to a new enclosure when you outgrow the initial setup.
The DS923+ remains compact for everyday use. The 4-bay size fits easily on a desk or shelf while still offering room to grow.
The expansion works only with the DX517 unit. No other expansion options are supported, so plan for that specific add-on if you need more storage.
