What is the best storage setup for a small business?

A NAS for shared, always-on storage with redundancy, plus a solid backup including an offsite copy. The NAS lets staff access files from any device, redundancy keeps it running through a drive failure, and the backup protects against deletion, ransomware and disaster.

Does a small business need a NAS?

If more than one person needs to access shared files, usually yes. A NAS centralises storage, handles permissions, and stays available to everyone. For a single user, a couple of external drives may be enough, but teams benefit hugely from shared, redundant storage.

How should a business back up its data?

Follow the 3-2-1 rule rigorously, because business data loss is costly. Keep multiple copies, on different media, with at least one offsite or in the cloud. Automate it, test that restores actually work, and never rely on a single device or RAID alone.

Setting up storage for a small business and want to get it right without overspending? The good news is the recipe is simple, and the same principles that protect a serious home setup scale neatly to a small team.

Shared storage that is always available, redundancy so a failure does not stop work, and rigorous backups because business data loss is expensive.

The table above shows the live price per TB on your marketplace for the drives that underpin it all.

Step 1: shared, always-on storage

For a team, the heart of the setup is a NAS.

A NAS gives everyone access to shared files from any device, with permissions so the right people see the right things. It is always on, so files are available whenever staff need them, without one person’s computer having to be running.

For a single user, a couple of external drives might do. But the moment more than one person needs shared access, a NAS is the sensible centre of your storage.

We walk through building one in how to build your first NAS.

Step 2: redundancy so work never stops

Downtime costs a business money, so plan for drive failure.

Run your NAS drives in a redundant setup so any single drive can fail without losing data or halting work. For most small businesses, a level that survives two failures gives comfortable peace of mind.

Redundancy is not optional at the business level. A dead drive should be a quiet swap, not a crisis. We cover the options in how many drives can you lose.

Step 3: serious backups

This is the step that saves the business, so do it properly.

Remember, redundancy is not a backup. It protects against hardware failure, not against an accidental delete, ransomware, or a fire in the office. For those, you need real backups.

Follow the 3-2-1 rule strictly: multiple copies, different media, at least one offsite or in the cloud. Automate it, and crucially, test that your restores actually work. We explain it in how to back up your data.

Step 4: buy reliable drives at good value

The foundation under all of it.

Choose NAS or enterprise drives built for constant use, and buy on the best price per TB. Refurbished enterprise drives can stretch a budget while keeping enterprise build quality, ideal when you run redundancy anyway.

Sort the live table above by price per TB and buy the value sweet spot, in the right quantity for your capacity plus redundancy.

The bottom line

The best small business storage is a NAS for shared, always-on access, run with redundancy so a drive failure never stops work, plus rigorous 3-2-1 backups with an offsite copy.

Buy reliable drives at the best price per TB from the live table above, automate your backups, and test your restores. Get those right and your business data is both available and safe, which is exactly what it needs to bee.
