Your Small Business Network Storage Buying Guide

Choosing the right network storage device is a big step for any small business. This device, often called a NAS (Network Attached Storage), keeps your important files safe and lets everyone in your office access them easily. Think of it as a shared, super-secure filing cabinet on your office network. This guide will help you pick the best one.

1. Key Features to Look For

When shopping, focus on these important features:

  • Capacity (How Much Space?): How many files do you have now? How much will you have next year? Start with enough space, but make sure the device lets you add more drives later.
  • RAID Support: RAID (Redundant Array of Independent Disks) is crucial. It lets you use multiple hard drives together. If one drive fails, your data is safe on the others. Look for RAID 1 (mirroring) or RAID 5 (striping with parity) for good protection.
  • Speed (Connectivity): Look for Gigabit Ethernet (1GbE) ports as a minimum. If you move very large files often, consider 2.5GbE or 10GbE connections for faster access.
  • Backup Software: Does the device come with easy software to back up your computers automatically? This feature saves you a lot of time.
  • Remote Access: Can employees securely access files when they are working from home? Good remote access keeps productivity high.

Factors That Improve or Reduce Quality

The quality of your NAS depends on its parts and how well it handles problems.

Quality Boosters:
  • Processor (CPU): A faster CPU means the device can handle more users at once and run backup apps smoothly.
  • RAM (Memory): More RAM helps the NAS run many tasks without slowing down.
  • Hot-Swappable Bays: These bays let you swap out a failed hard drive without turning the whole system off. This keeps your business running smoothly.
Quality Reducers:
  • Proprietary Software: If the company locks you into their specific, hard-to-use software, it lowers your long-term options.
  • Slow Network Ports: Using only older 100Mbps ports drastically slows down file sharing.

2. Important Materials and Build

Most network storage devices use strong metal or tough plastic casings. Metal cases generally offer better airflow, which keeps the hard drives cooler.

Hard Drive Type Matters:

You need to decide between two main drive types:

  • HDDs (Hard Disk Drives): These offer the most storage for the lowest price. They are great for archiving large amounts of data.
  • SSDs (Solid State Drives): These are much faster but cost more per gigabyte. They are best for running applications directly from the NAS.

Tip: For small businesses, using NAS-rated HDDs is usually the best starting point.

3. User Experience and Use Cases

A good NAS should feel simple, not complicated. A user-friendly interface (the dashboard you use to manage the device) makes setup and maintenance much easier.

Common Small Business Use Cases:
  • Centralized File Sharing: Everyone accesses the same, most recent version of documents (e.g., client contracts, marketing materials).
  • Video Surveillance Recording: Many NAS devices can record video from IP security cameras 24/7.
  • Virtual Machine Storage: If you run small virtual computers on your network, the NAS can hold their large files.
  • Cloud Synchronization: The device can automatically sync important folders to a public cloud service (like Dropbox or Google Drive) for an extra layer of safety.

10 Frequently Asked Questions (FAQ) About Small Business Network Storage

Q: What is the main difference between a NAS and a regular external hard drive?

A: A regular drive plugs into one computer. A NAS plugs into your network router, letting many people access the files at the same time over the network.

Q: Do I need to buy the hard drives separately?

A: Some models come pre-loaded with drives, while others are “diskless,” meaning you buy and install the drives yourself. Diskless options offer better customization.

Q: How important is RAID protection for a small office?

A: RAID is very important. It protects your data if one hard drive suddenly stops working. Without it, losing one drive means losing your files.

Q: Can I use my NAS to host my company website?

A: Most standard small business NAS units are not designed to host public websites efficiently. They are best used for internal file storage and backups.

Q: What does “2-bay” or “4-bay” mean?

A: This refers to the number of hard drive slots inside the unit. A 4-bay unit lets you install four hard drives for more capacity or better RAID protection.

Q: How fast should the network connection be?

A: Look for a device with at least one Gigabit Ethernet (1GbE) port. This offers fast file transfers for most small office needs.

Q: Will setting up a NAS be too complicated for my staff?

A: Modern NAS devices use simple, web-based setup wizards. Many popular brands are designed so that a tech-savvy employee can set them up without hiring an IT consultant.

Q: How often should I check the health of my drives?

A: Good NAS systems monitor drive health automatically. You should check the system dashboard weekly to ensure all drives are reporting “healthy” status.

Q: Can I use my NAS for video editing directly?

A: If the NAS has a very fast processor and a 10GbE connection, yes. For most offices, it is better to copy the video files to a local computer before editing them.

Q: Is security a concern if the device is on my network?

A: Yes, security is a concern. Always use strong passwords, keep the NAS firmware updated, and only enable remote access features if you truly need them.
