Quick answer

The calculator is set to the four bays of the DS425+ and the RAID types Synology lists for it. With the largest drive on the compatibility list, 24TB, the bays hold 96TB raw and 72TB in SHR, one drive of protection. The DS425+ cannot be expanded.

With 4x 8TB in Synology SHR you get about 21.83 TB usable and 1-drive fault tolerance. At the cheapest live NAS price per terabyte ($36.36/TB), filling these bays costs about $1164.

Usable capacity is shown after binary and filesystem overhead (about 9%). Fault tolerance is not a backup; keep a separate copy of important data.

How much storage fits the DS425+, by drive size

20TB	80TB	60TB	40TB
24TB	96TB	72TB	48TB

Limits that are specific to the DS425+

A full set of 24TB drives in SHR gives 72TB, which is inside the DS425+'s 108TB single-volume limit, so the limit never constrains the internal bays.

The DS425+ supports up to 32 internal volumes.

Where the DS425+ figures come from
