NAS devices for data storage: A Comparative Guide

People often work on their computers accessing common data files at the same time. In such scenarios, efficient and secure data storage and sharing becomes paramount. Both businesses and individuals use NAS (Network Attached Storage) devices to store, share and manage data while working on common projects.

What are NAS devices for data storage?

NAS devices are hardware that can be connected to a Local Area Network (LAN) in an office or home. All active users in the LAN can access the device simultaneously, store and manage files. That is, a NAS device offers centralized storage, easy accessibility and robust data management in a network system.

Before choosing a NAS device, think about..

There are multiple NAS devices available in the market. From these, how do you know which one is best for you? Before selecting NAS devices for data storage in your home or office, keep the following things in mind:

1. Storage capacity of the device

Assess your current and future data storage needs. That, in turn, depends on your team size and RAID (Redundant Array of Independent Disks) configuration of the hard disk in the NAS device.

A NAS device has Bays that hold internal hard disks. More Bays in a NAS device mean you can add more hard disks into it. More hard disks mean more data storage capacity.

Generally, for homes and small size companies, a 2-Bay NAS device would be enough. Whereas, big companies with larger volumes of data may need 4-Bay, 8-Bay or 16-Bay NAS solutions.

Depending on your data storage needs, you can determine how many hard disks you need for your NAS device. Here is a useful tool to calculate that- QNAP RAID Calculator.

2. Performance

Look for NAS models with robust processors and RAM for multitasking. Depending on the type of files you would store, you can choose the processor. For a typical home user, entry level processors with basic RAM would be enough. Whereas for professional users working with rendering, designing or programs requiring heavy files need high-end processors with RAM 16GB, 32GB or more.

3. Connectivity

If you work often with files like MS Word, MS Excel, then an ethernet port would be enough to meet your data requirements. But, if you do high-speed data transfers, look for Thunderbolt or Gigabit ethernet supporting ports in you NAS system.

4. Scalability of the NAS device

As time goes on, your data usage and team size can go up. Keeping that in mind, look for NAS devices that allow for future expansion.

If you don’t plan to expand your team soon, you may not want more Bays in your device right now. But still, its a good idea to keep a provision for some extra Bays. Yes, it can be tempting to buy a 2-Bay NAS because it’s cheaper. But, it’s always logical to buy a 4-Bay or 8-Bay device because they allow for future expansions.

Let’s look at an example. Say, you bought a 2-Bay NAS device. After a while, both hard disks in those 2 bays reached full capacity. Now you don’t have any free bays in your device to put new hard disks in!

To avoid such scenarios in future, you can buy a 4-Bay or 8-Bay device now itself instead of a 2-Bay one. Yes, that decision depends on your budget and other considerations. So in future, when the hard disks get full, you can get new hard disks, not an entirely new NAS device, and put in those free bays.

5. Security Features

Prioritize NAS device models with strong encryption and backup features. Because, if your files get hacked, you still have a backup of your data encrypted.

After reading till here, you now know what all things to look for before selecting a NAS device.
