2 perspectives. One decision.
Synology DS224+ vs DS923+: two bays or four?
A smaller two-bay NAS and a more expandable four-bay model compared around capacity, memory, workload and the cost of growing later.
The short answer
The DS224+ is the simpler fit for basic backup, file sharing and a smaller drive plan. The DS923+ offers four bays and more memory from the start, which gives it more room for capacity and heavier workloads. Drive cost, backup strategy and network speed should be planned before choosing either enclosure.

Start with usable capacity
A two-bay and four-bay NAS can use the same drive family but produce very different storage plans. Redundancy reduces usable capacity, and backup still requires another copy elsewhere. Calculate the data you have now, expected growth and the space needed for snapshots before choosing the enclosure.
More bays change the upgrade path
Four bays allow more combinations of capacity and redundancy. They can also delay the moment when every installed drive has to be replaced. The tradeoff is a larger initial drive budget and more hardware to power and maintain.
Applications and memory
The DS923+ starts with more memory and ECC support. That matters more when the NAS will run several packages, serve multiple users or take on workloads beyond straightforward file storage. The DS224+ remains a more direct appliance for lighter use.
Network reality
A faster storage pool does not automatically make transfers faster. Client Wi-Fi, Ethernet ports, switches and cabling can become the limit. Map the entire route between computer and NAS before paying for performance the network cannot deliver.
