How we chose
We weighted software maturity highest, because a NAS lives or dies by its OS over a five-plus-year lifespan. Next came network throughput (1GbE vs 2.5GbE is a real, measurable gap), then RAM and CPU headroom for media and container workloads, and finally bay count for expansion. Every spec cited comes from manufacturer documentation or published expert testing.
Questions, answered
Do NAS devices come with hard drives?
Almost never. Enclosures are sold diskless; you buy NAS-rated drives (such as WD Red or Seagate IronWolf) separately. Budget for drives on top of the enclosure price.
How much RAM does a home NAS need?
For file storage and backups, 1 GB is workable. For Plex, Docker, or virtual machines, 2 GB is the practical minimum and expandability matters, which is why the DS423+ stands out.
Is 2.5GbE worth it over gigabit?
If you move multi-gigabyte files regularly (video editing, large backups), yes: 2.5GbE roughly doubles real-world transfer speeds versus 1GbE. You will also need a 2.5GbE switch and a 2.5GbE adapter on your computer to see the benefit.
Can a NAS replace cloud storage subscriptions?
For file sync and backup, largely yes, with no monthly fee. For off-site protection against fire or theft, keep at least one backup copy elsewhere, since a NAS in your home is still a single location.
