Choose protected capacity, simple administration, and a second copy outside the NAS.

2 bays · 1 × 1GbE

DSM, Btrfs, Hyper Backup, and low operating complexity matter more than 2.5GbE for a straightforward household backup target.

Watch: Fixed 2GB memory, 1GbE, and two bays leave little performance or capacity headroom.

Four bays, ECC memory, dual 2.5GbE, snapshots, and one open bay create a stronger growth path without giving up DSM administration.

Watch: The Ryzen platform lacks an iGPU, and exact third-party drive support must be rechecked under the installed DSM release.

DS1825+

8 bays · 2 × 2.5GbE

$1,449.99$181.25/bay · 2 priced stores

Eight bays, ECC memory, expansion options, and DSM backup tooling fit large multi-device archives where restore organization matters more than benchmark leadership.

Watch: Six large Pro drives are audible and expensive; the recommendation assumes a genuinely large dataset and a separate off-site copy.

Selection rules

  1. 1Start with current data, add three to five years of growth, then keep roughly 20% free.
  2. 2Choose two bays for a simple mirror; choose four bays when capacity will grow or multiple jobs share the NAS.
  3. 3Prefer straightforward backup software and administration over unused processor features.

Common mistakes

  • Treating RAID as the only backup
  • Buying raw capacity instead of protected capacity
  • Ignoring restore testing
