How to choose a NAS for home: buyer’s guide

  • Capacity & expandability: Decide how much storage you need now and in the near future. Diskless units require you to buy drives separately, while prebuilt consumer devices come with internal drives (for example, the WD My Cloud Home 4 TB).
  • Number of bays: More bays mean more drives, more raw capacity, and more RAID options. A 4-bay like the Synology DS920+ offers more growth room than a 2-bay DS220+ or QNAP TS-231K.
  • Software and apps: The NAS operating environment affects ease of use and available services. Synology DiskStation products run Synology DSM; the QNAP TS-231K offers Qfile mobile app access; WD My Cloud Home is positioned as a consumer personal cloud for centralized backups.
  • Ease of use vs. power: If you want a feature-rich OS and expandability, a DiskStation typically provides advanced tools. If you prefer simple, preconfigured backup and minimal setup, a consumer personal cloud may be a better fit.
  • Network basics: Check your home network — devices with multiple LAN ports (like QNAP’s two 1GbE ports) can be useful in certain setups. Confirm your router and switches are appropriate for NAS traffic.
