Choose a network-attached storage device around what you need to store, who needs access and how you will recover the files if something goes wrong. Drive-bay count and processor names are only part of the decision. A suitable NAS also needs a workable backup plan, compatible applications and software support you can maintain.
Calculate usable capacity, not just installed drives
Measure your current files and estimate their growth. Add room for versions, snapshots and applications if you intend to use them. Then check the exact storage layout’s usable capacity rather than adding together every drive label.
For example, two equal 8TB drives mirrored as RAID 1 provide roughly one drive’s nominal capacity before formatting and system overhead, not 16TB of usable mirrored storage. Mirroring keeps a second copy within the array; it does not make two independent backup destinations. QNAP’s RAID documentation describes how layouts differ.
Check the model’s drive-compatibility list, supported capacity and expansion process. An empty bay does not prove that any later drive can be added without migration, a rebuild or a new storage layout.
Separate availability from recovery
QNAP explains why RAID is not a backup: redundancy within an array does not cover every way files can be lost. Deletion, malicious changes, theft or a failure affecting the whole unit need a separate recovery plan.
Decide which files will be backed up to another destination, how often and who will check the jobs. Synchronisation alone can copy an unwanted change to the other location. Check whether the chosen backup retains recoverable versions and test restoring a sample file before relying on it.
If the NAS holds the only copy of a family photo library, that library still needs an independent backup. A second disk in the same enclosure is not an off-site copy.
Match performance to the whole network
List the jobs: shared documents, several simultaneous users, video editing, media playback or virtual machines. Check the requirements of the exact applications, including codecs and transcoding support where relevant. There is no single minimum RAM figure that suits every workload.
Follow the data path from NAS to computer: the NAS port, switch, router where involved, cable and client adapter can each be a limit. A 10GbE NAS cannot provide a 10GbE connection through an intervening gigabit link. Compare workload-relevant measurements rather than choosing a processor brand alone.
Plan access and ongoing maintenance
Create separate accounts and permissions, keep software updated and check the available authentication and encryption options. Decide whether remote access is actually needed. Do not expose services to the internet simply because a setup wizard offers the option.
Check update support, app availability, account recovery, replacement-drive procedures and how you would retrieve files if the enclosure failed. Write down the total budget for disks, independent backups, network changes, power and any paid software. A NAS is easier to judge when its running and recovery costs are included with the enclosure price.
