Best NAS for a Homelab (2026): How to Choose

A NAS keeps backups, datasets, media and shared project files on the network, and many run containers for self-hosted tools. In an AI homelab it is usually the storage layer, with models running on a separate machine with a graphics card or unified memory.

Picks cover the enclosure, the drives and the gear around it.

Quick picks by situation

  1. Best for backups and a first NAS

    2-bay NAS enclosure (diskless)

    Who it's for
    People who want mirrored backups and shared files without much setup.
    Why
    Two mirrored drives keep a copy if one fails, and a two-bay unit is small and quiet.
    Skip if
    You expect to add drives later; a four-bay unit leaves room.
    What to check
    Drives are sold separately. Check supported drive sizes, the network ports and whether it runs the containers or apps you want.
    See options on Amazon

  2. Best for growing storage and redundancy

    4-bay NAS enclosure (diskless)

    Who it's for
    Homelabs with datasets, media and backups from several machines.
    Why
    Four bays allow RAID levels that survive a drive failure while adding capacity over time.
    Skip if
    You only need backups for one or two machines.
    What to check
    Check the CPU and RAM if you plan to run containers, the network ports (2.5GbE or faster), and M.2 cache slots.
    See options on Amazon

  3. Pair with: NAS-rated drives

    Large NAS drive for archives and backups

    Who it's for
    Anyone filling a NAS.
    Why
    NAS-rated drives are designed for always-on use in multi-bay enclosures.
    Skip if
    Your NAS will hold SSDs only.
    What to check
    Use CMR drives rather than SMR in RAID (check the maker's spec sheet), and check the NAS maker's compatibility list.
    See options on Amazon

  4. Pair with: a 2.5GbE switch

    2.5GbE network switch

    Who it's for
    Homelabs where the NAS and computers have 2.5GbE ports.
    Why
    1GbE caps transfers at 125 MB/s in theory, which a multi-drive NAS can exceed.
    Skip if
    Your devices only have 1GbE ports.
    What to check
    Count the ports you need, and choose managed only if you want VLANs.
    See options on Amazon

  5. Pair with: a UPS

    UPS for always-on services

    Who it's for
    Anyone whose NAS stays on around the clock.
    Why
    A UPS rides through short outages and can signal the NAS to shut down cleanly.
    Skip if
    The NAS already shares a UPS with your network gear and the load fits.
    What to check
    Check that the NAS supports the UPS over USB or the network, and size the UPS for the combined load.
    See options on Amazon

How to choose

Bays and redundancy

Two bays allow a mirror; four or more allow RAID levels that combine capacity with one- or two-drive fault tolerance. RAID keeps the NAS running through a drive failure, but it is not a backup: keep a second copy elsewhere.

Drives

Use NAS-rated CMR drives for RAID and check the NAS maker's compatibility list. Buying drives from different batches can lower the chance of two failing close together.

Network speed

Many NAS units now have 2.5GbE ports; some offer 10GbE or an expansion slot for it. The network only helps if your switch and computers match.

Apps and containers

If you want the NAS to run self-hosted tools, check its CPU, RAM (and whether it is upgradable) and container support. Heavier AI work belongs on a separate machine.

FAQ

Is RAID a backup?

No. RAID protects against a drive failure, not against deletion, ransomware or a failed NAS. Keep a separate backup, ideally off-site.

Can a NAS run AI models?

Most NAS processors are built for storage. They can run small tools in containers, but run models on a separate machine with a graphics card or unified memory and keep model files on the NAS if you like.

How many bays do I need?

Two for mirrored backups of a few machines; four or more if you want to add capacity over time or use RAID with one-drive fault tolerance and more space.

How we picked

  • We picked the parts of a homelab storage setup that have to work together: enclosure, drives, network and power.
  • Links open Amazon searches by spec, not a single listing, so you compare current models, prices and reviews yourself.
  • We have not tested these products hands-on for this guide and make no claims about speed or how any listing performs.
