Two-bay desktop
Compact file, photo and backup servers where capacity growth is intentionally bounded
Current market guide
Prosumer NAS storage
Desktop network storage, drive bays and compatibility, file systems, snapshots, replication, network interfaces, applications, expansion, power protection, support and a backup plan that remains separate from RAID
Your place in the market
Start with the questions that remove bad fits
Start with data, users, applications, growth, recovery targets and a separate backup copy
01
Before the shortlist
The first four answers do most of the work
A useful ranking starts only after the constraints specific to this market are clear.
- 01
Which data must survive device failure, theft, fire, accidental deletion or account compromise?
- 02
How much usable capacity is needed now and after three to five years of growth?
- 03
Will the NAS serve files only, or also photos, containers, virtual machines, cameras or media?
- 04
Where will an independent offline or off-site backup live, and how will restores be tested?
02
Market education
Read only as far as you need
The path changes with your research stage. Each guide is built around a decision that removes part of the market.
01Start here
Design data, capacity and backup
Usable storage, growth, failure tolerance and independent recovery decide the useful system
02comparingCompare hardware, OS and applications
Bays, processor, memory, networking and the supported software stack belong in one comparison
03comparingCommission, secure and test restore
Drive checks, updates, accounts, UPS, remote access and a real restore complete the purchase
03
Buying paths
The shortlist covers different ways to own the product

Market language
The terms a useful comparison should define
- RAID
- A multi-drive layout that can preserve availability after some drive failures; it is not a separate backup copy
- Snapshot
- A point-in-time file-system reference that can help recover earlier data states when retained and protected correctly
- ECC memory
- Memory able to detect and correct some bit errors, subject to the processor, board and installed module
- Immutable backup
- A backup copy configured so the protected data cannot be altered during its retention window
