Buying Guide: How to Choose the Best NAS for Time Machine?
SMB3 Protocol Requirement
Apple deprecated the AFP (Apple Filing Protocol) starting with macOS Big Sur, moving entirely to SMB3. Any NAS you choose must support SMB3 for Time Machine compatibility. This transition caused issues for older NAS units that only supported AFP, so verify SMB3 support before purchasing.
All the NAS devices in this roundup support SMB3, keeping them compatible with current and future macOS versions. This single requirement eliminates many older and cheaper NAS units from consideration.
RAID Configuration Explained
RAID determines how your data spans across multiple drives. RAID 0 stripes data across drives for maximum speed but offers zero redundancy. RAID 1 mirrors data between two drives, protecting against single drive failure.
RAID 5 stripes data across three or more drives with parity, allowing recovery if one drive fails. For Time Machine backups, RAID 1 or RAID 5 provides the redundancy needed for true data protection.
Synology’s SHR (Synology Hybrid RAID) offers flexibility by allowing mixed drive sizes while maintaining redundancy. If you plan to start small and add larger drives later, SHR makes that upgrade path painless.
Drive Bay Count Considerations
2-bay NAS units work well for 1-2 Macs with typical storage needs. They support RAID 1 mirroring for drive failure protection. 4-bay NAS units offer more capacity and RAID 5/6 options for better redundancy.
4-bay and 6-bay units suit multi-Mac households or users with large media libraries. Consider your current storage plus 2-3 years of growth when choosing bay count.
Network Speed Requirements
Standard 1GbE ethernet handles Time Machine backups adequately for most users. Initial backups of hundreds of gigabytes take hours, but subsequent hourly backups complete quickly.
2.5GbE ethernet reduces initial backup time significantly if you have compatible network equipment. For large file transfers or multi-user environments, the speed improvement matters. Link aggregation with dual ethernet ports can double throughput on compatible network switches.
Software Ecosystem Quality
Synology’s DSM operating system offers the most polished experience for Mac users. The app ecosystem includes photo backup, file syncing, surveillance, and media server applications. QNAP’s QTS provides extensive features but requires more configuration.
UGREEN and TerraMaster offer functional software with fewer app options. For Time Machine specifically, Synology’s guided setup reduces complexity for first-time NAS users.
Multi-Mac Household Considerations
When backing up multiple Macs to one NAS, create separate Time Machine shared folders for each computer. Set quota limits to prevent one Mac from consuming all available space.
The initial backup from each Mac will run consecutively if started at similar times, so stagger them across different days. More RAM helps the NAS handle multiple simultaneous backup operations without slowdown.
