Network Attached Storage (NAS) is essential for modern households with multiple devices. It provides centralized backups to prevent data loss and serves as a powerful media server for the whole family. Whether you're seeking pre-built options or DIY solutions for a Plex server, we've tested and selected the top performers.
In fact, NAS offers superior backup capabilities, with most models featuring redundant drives that mirror your primary storage to protect against drive failure.
This guide draws from hands-on experience to highlight key features and recommend the best 2-bay NAS devices that excel as both backups and Plex media servers. All support Plex (installable if needed), and you'll need to supply your own hard drives.
We prioritize user-friendly interfaces from trusted brands like Synology, QNAP, and Western Digital, which include intuitive apps for remote access—even via VPN.
For home use, focus on 2-bay models with RAID mirroring: one drive for storage, the second as a backup. Ideal for phones, tablets, and computers. Plex compatibility is key for media streaming.
