For any London based small business it’s critical to have an effective way to store files and share it among staff.  Any company with more than 2 or 3 staff members who need to access the same data should be implementing some sort of storage system.  There are 3 basic choices:

  1. Keep files locally in the office, with daily cloud backups
  2. Keep files locally in the office, with no cloud backups
  3. Keep files in the cloud

It’s quite common to see small businesses who aren’t operating with any of the above setups because they simply don’t realise the pros and cons of each approach. In this article, we’ll be looking at the hardware options available to keeping data in the office.  In a nutshell, there are 2 choices:

  1. NAS (Network Attached Storage) device
  2. Server

If you’re uncertain which type of device your business needs, please continue reading.

What is a server?

A server is not dramatically different from a regular PC, but it serves a different purpose. The main role of a server is to manage resources on the network. The server will be using a server operating system such as Windows Server or Mac OS X Server. A server can fill a number of different roles, all of which manage resources and clients on the network. Potential server capabilities include:

  • Active directory domain controller –> authenticates and authoriSes all users and computers on the network
  • DHCP Server – dynamically assigns IP addresses to devices on the network
  • DNS Server – associates IP addresses with domain names
  • Printing and Document Services
  • File storage, sharing and collaboration tools
  • User or Device Specific Permissions
  • Applications – applications installed on server that are accessible to clients (accounting software, e-commerce software, etc.)

What is a NAS?

NAS stands for network-attached storage. As you can derive from the name, a NAS is attached to a network and stores data. It’s a device that is specialised to provide data storage and make it easily accessible. A NAS provides a central location to allow for synced folders that can be accessed and modified by others on the network. It is also useful for backing up data locally. In addition to file storage and sharing, NAS devices offer many of the same services that an application server can, but with more basic settings and less customisation. It also requires you to use its own compatible applications, rather than choosing from any third party software.

Which device suits your small London business?

To decide whether a NAS or server will best suit your small business, break down the benefits of each in the following categories:

Functionality and Ease of Use

Servers allow you to install third-party software. With a NAS, you are limited to applications you can download on the NAS operating system. Servers are more capable and offer more advanced controls over your network services and applications, but also require more management. The NAS offers less advanced functionality, but will not require as much maintenance or configuration. totality services clients need not worry about the configuration and maintenance aspect, as that’s included with all IT support contracts.

Sharing Capabilities

Both servers and NAS provide a great way to share files across devices on the network with the use of shared folders. Both a server and NAS allow for control over user permissions. User groups can be created that make files only accessible to those who should have access. The server will arguably offer more configuration options in terms of access control and security than a NAS will.


With the difference in functionality, comes a difference in cost. A server contains more powerful hardware and offers more functionality. The tradeoff is that it will cost more than a NAS. A server will almost always cost more than a NAS. Server operating systems also drive up the price because they often require purchasing licenses for the server, and in some cases, licenses (or CALs) for each user or device connecting to the server. On the other hand, most NAS software comes with the NAS device and does not require user licensing.


For a small London based business, a server setup will improve efficiency and reliability. When choosing a server device, you must consider the needs of your business as well as your budget. For those seeking higher functionality and can handle the more complicated configuration, maintenance, and higher cost, aserver is the best choice. For those whose are looking for a good file storage and sharing solution, with other basic applications, a NAS is a more affordable option.
