How much storage capacity do I actually need?

Calculate based on what you're storing: 4TB works for photos and documents, but video editors and photographers should aim for 8TB+. Consider that you'll want some buffer space and room to grow—buying more than you currently need saves money versus upgrading later.

What's the difference between 2-bay and 4-bay NAS units?

A 2-bay unit suits small teams or home offices with basic backup needs, while 4-bay systems offer more storage capacity, better redundancy options, and room to expand. More bays also mean higher upfront cost but better protection if a drive fails.

Do I need to buy the hard drives separately?

Most NAS units don't include drives, so you'll need to purchase them separately—choose NAS-rated drives, not regular desktop drives, as they're built for 24/7 operation. Some models come in pre-loaded versions, which costs more upfront but saves the hassle of installation.

What processor and RAM specs matter for NAS performance?

For basic file storage and backup, modest specs are fine, but if you're running apps, handling 4K video, or supporting many users, look for a quad-core processor and at least 8GB RAM. This directly affects how fast files transfer and whether the system can handle multiple tasks simultaneously.

When should I spend more on a premium NAS instead of a budget model?

Upgrade if you need advanced features like app support, better performance for video work, or support for more drives. Budget models work fine for simple backup and file sharing, but premium units justify the cost when you need reliability for business-critical data or demanding workflows.
