NAS (Network Attached Storage) essentially connects a hard drive to your router via an Ethernet cable (often fast Gigabit Ethernet), therefore creating a storage share that can be accessed by your desktop PC, your tablet and sometimes even remotely.
They tend to be platform-agnostic, able to work with almost any device you connect to your wireless network – including DLNA-compatible devices (a standard for sharing media) such as smart TVs.
Think of them as supercharged external hard drives; mini servers, if you like. Indeed, many small businesses are now using NAS drives as an alternative to the expensive, power-hungry server they used to need to have in the cupboard.
WD has achieved quite considerable success with its unashamedly consumer-friendly My Cloud products, which can stream to any DLNA-compliant device and can be accessed via mobile apps for iOS and Android.
Labelled as a ‘personal cloud’, it’s a NAS box by any other measure and starts at 2TB of storage (you can also get it in 3 or 4TB). As it’s a one-bay unit, it can’t back itself up to a drive inside the unit, but it can back up to an external hard drive via a USB port on the back.
