With the vast amount of data we produce in today’s digital world—at home or in a business—photos, videos, documents, backups and software, all require recurring or potentially recurring, space and intelligent storage. It is at this moment that NAS (Network Attached Storage) becomes an effective solution.

What is a NAS?

A NAS (Network Attached Storage) is a storage appliance connected to your home or office network. Unlike traditional external hard drives, which are connected to one computer, a NAS system can be accessed by multiple devices over the network. NAS can be thought of as your own private cloud that you manage and control with no monthly subscription charge, no data mining, and safely stored and managed in your dusty old comms cabinet. NAS appliances are really mini-computers with hard drives, by design, they are built to efficiently store and share data to over a network.

Why You Might Need a NAS

A NAS could be a life-changing tool – for a SMB, content creator or simply someone who has seen their digital life grow over time.

Here are some of the reasons why:

Centralized file storage – Store everything in one spot and access from any device on the network.
Automatic backup – You can setup backup schedules to back to the NAS using something called snapshots.
Cloud backup – Transfer your backed up data or snapshots to a cloud service like Wasabi or Amazon S3.
Media streaming – Stream movies, music or photos directly from your NAS on smart TVs or mobile devices.
Remote access – Have the ability to access your files from anywhere in the world.
Data redundancy – Protect your data by utilizing RAID configurations that would mirror or stripe disks.

In a nutshell, a network attached storage solution provides comfort, safety, and efficiency.
