Network Attached Storage (NAS) allows multiple users to store and share files in a centralised location rather than individuals storing files on their own computers. By using Network Attached Storage documents, reports, music and videos can be shared with anyone who has access to the network making NAS an ideal business storage solution.

NAS Solutions from

In today's digital world all businesses, both small and large, need a system for everyone in the company to easily access files, create back-ups and share devices such as printers. Which is why NAS (Network Attached Storage) may be the solution your business has been looking for.

What Is Network Attached Storage?

It may be beneficial to think of NAS as a standalone hard drive that is wirelessly connected to all the computers in the business. This network of users can then store and access files on the NAS so that anyone can retrieve them.

For businesses this makes data management so much simpler especially when a team is working on a joint project. Documents and other digital media no longer need to be emailed around the office but can be easily placed on the NAS for sharing.

A huge plus point in favour of Network Attached Storage is that it is possible to set up remote access. Forgotten that report you needed to work on at home? No problem. Just remotely log into NAS and retrieve the file.

Desktop Or Rack?

NAS can be configured as either a desktop or rack mounted system. For small businesses or where space is an issue a desktop solution would be advisable. However enterprise users may be wise to invest in a rack mounted system.

Whichever system you decide to install for your business you can find everything you need on from manufacturers such as Synology, QNAP and Buffalo.

Storage & Protection

You can store a huge amount of data on NAS, and has a wide range of capacities to fit every requirement. Furthermore you will need to protect your data, so RAID (Redundant Array of Independent Disks) is a key feature allowing data to be written across multiple drives to ensure data is not lost should a drive fail.

With businesses of all sizes becoming more reliant on technology, both in the way they operate and in how they store information, most are now realising the benefit of investing in Network Attached Storage (NAS).

With NAS data can be easily stored, shared and secured. Everyone in the business will be able to access the information on the NAS, share devices such as printers and will even be able to remotely dial in to the system no matter where they are in the world.

NAS network attached storage

Although NAS devices are ideal for businesses they are increasingly being used in the home. Home NAS systems usually have a lower storage capacity but can be used to store all data from the family’s computers, their smartphones and tablet PCs and can also stream media and run the Smart TV. And, as most home NAS devices come with extra cloud storage, photos and videos can be easily shared with extended family members no matter where they are located.

What is NAS?

Before looking at which NAS drive will best suit your situation in more detail let’s first explain exactly what Network Attached Storage is. The easy way to think about NAS is as a high capacity external hard drive that has a load of extra bells and whistles which is wirelessly connected to every computer and device on your network.

The advantages of this is that everyone using a computer in the network can save data onto the NAS or access the information that is already stored there.

This makes it so much easier and more convenient when working as a team as documents no longer have to be emailed between colleagues but rather can be centrally accessed, edited and shared.

In addition printers and other devices can be connected to the NAS which again makes a much more convenient solution.
Basically anyone with access to the network can log onto any computer on any desk and access information and then use the nearest printer to make a hard copy. The benefits of this are obvious and will be a huge boost to productivity.

Another advantage of using NAS is that the data is much more secure as access to the drive can be controlled and with hot swappable disks and RAID a hardware failure won’t result in lost data.

And, of course, one of the biggest benefits to installing NAS onto a network is the sheer volume of data that can be stored and retrieved. The storage capacity can be increased as the business and demand grows with multiple drives and enclosures added when necessary.

Although all NAS devices are different the main features are:

Number of drives

NAS enclosures are available with different numbers of bays – some will of course already have built-in drives whereas others will be diskless bays. At you are able to find an enclosure with anything from a single bay all the way up to 24 bays with 4 or 8 bay solutions being very popular.

Hot swappable disks

This is a very useful, possibly essential, feature found in many NAS solutions. In the event of a hot swappable disk failing it can be replaced without having to power off the NAS. In the meantime though the NAS will still be able to function without the failed disk.

Network connectivity

nas network

The vast majority of NAS enclosures use wired Gigabit Ethernet connectivity. This is the fastest and most reliable solution especially as most enclosures will have multiple Gigabit ports that can be linked to provide redundancy in case of one failing. Similarly, look out for multiple Ethernet ports as they can also be linked to increase data transfer speed.
Wireless NAS are much less common and don’t provide the reliable streaming and uploading of wired models.

Remote access

The convenience of remote access shouldn’t be under estimated. Many NAS devices have this capability and it allows data to be retrieved by anyone with network access no matter where they are. For example an executive in a meeting can pull up information when required or a colleague working at home can access and then save reports to the NAS.

Automatic backup

Every NAS device should come with pre-installed software that automatically schedules and carries out back up. On the next page of our NAS buyers guide we will look at choosing the best solution for you.

To assess which enclosure is best for you look at the features listed within each product description. However, every NAS device is different, so decide on what you need it for and then browse the wide selection available on Carefully read the product descriptions and technical specifications to ensure the NAS will meet your requirements.

network attached storage

But to find the best solution for you try asking yourself the following questions:

What capacity?

The first, and most obvious question when thinking about NAS, is how much storage space do you need? NAS drives are available in different sizes ranging from one terabyte up to six terabytes. Of course you aren’t restricted to just one drive and depending on which solution you decide upon you can have up to eight drives.

However as a guide to the number of terabytes you may need on a single drive one terabytes is roughly equivalent to 682,000 15 second Instagram videos, 333,000 MP3 files or 250 HD movies.

Pre-installed drives or diskless solutions?

When buying NAS enclosures from you will find models with and without built-in drives. Buying a device complete with drives has the advantage of convenience as everything is configured and installed. But many will prefer a diskless system so they are not restricted to just one manufacturer and can source the best value drives to install themselves.

What about security?

It’s important to keep your network secure and NAS can help with how data, files and information is shared among the network. Ensure you are able to create the type of access that will suit your business. For example you could allow blanket access or create areas that are only accessible by password.

Data protection

Protecting all your essential files and valuable data is of course essential and with NAS the degree of protection is very much linked to the number of drives. For the smaller business it may seem that a single drive is sufficient and, in terms of storage volume, that may be correct. However should there be a hardware failure the results would be catastrophic with all data lost.

However, having multiple NAS drives not only massively increases the storage capacity, but enables RAID to be set up. RAID (Redundant Array of Independent Disks) is a way of setting up two or more NAS drives so that data is copied across multiple disks. So, if one disk fails, it can be simply removed and replaced with no loss of data. Setting up RAID is recommended for businesses of all sizes that have a network. There are however different types of RAID which are differentiated by a number. The most common types are RAID1 and RAID5.

What is RAID?

RAID1 is the simplest system to configure and only requires two disks the second of which simply mirrors the first. If one disk fails the same information is stored on the second disk thereby preventing any data loss. The disadvantage with RAID1 is that storage capacity is effectively halved.

RAID5 on the other hand offers more flexibility in that multiple disks are used so the storage capacity can be massive. RAID5 is also highly secure as data is striped, or saved, across all the disks in the array with parity blocks created on each disk.

nas drives

This means that in the event of a disk failing it is simply replaced, or hot swapped, with another disk. The data is then rebuilt using the parity blocks from the other disks in the array.

NAS Drives

Once you have a NAS enclosure in place you need to fill the bays with hard drives. These drives, by leading brands HGST, Seagate and, of course, Western Digital are specifically manufactured for NAS enclosures as they need to have a large capacity, robust reliability and fast data transfer speeds.

Many NAS drives will be cross compatible with other manufacturers enclosures which means the best value drives can be purchased irrespective of the brand (though it is always advisable to check compatibility).
