Frequently Asked Questions
Does the DS225+ come with hard drives already installed and configured?
Yes. It ships with two genuine Synology HAT3300-4T 4TB drives set up in RAID 1, with DSM already installed, so it is ready to run on arrival.
How much usable storage does the RAID 1 setup actually provide?
Because RAID 1 mirrors the two 4TB drives, usable capacity is roughly 4TB. The mirror trades total space for redundancy against a single drive failure.
Can I add more memory to the DS225+ later?
Yes. It comes with 2GB of DDR4 that can be expanded up to 6GB, giving some added headroom for busier file-sharing and backup workloads.
What kind of workloads is this NAS best suited for?
It targets everyday file sharing, backup, and multimedia in small offices and departments. The Celeron J4125 and two-bay design suit modest deployments rather than heavy compute.
Can the DS225+ be used to manage security cameras?
Yes. It supports Surveillance Station, so the same unit can serve as a network camera server alongside its file-sharing and backup roles.
Does it offer any features for more reliable, always-on operation?
It includes a hardware encryption engine and supports Synology High Availability, aimed at environments that want more stable and dependable operation.
