NAS: Centralised Storage for Your Network
A NAS (Network Attached Storage) is a network storage device that connects to your router or network switch via LAN. This allows multiple devices, such as PCs, laptops and smartphones, to access centrally stored files. NAS devices are suitable for backups, shared folders and media servers in home or office networks. Depending on the model, different network speeds, drive bays and features are available.
What Are the Benefits of Using a NAS on Your Network?
Unlike an external hard drive connected directly to a device, a NAS provides storage over your local network. This makes it suitable for a variety of uses:
- Shared File Access: Multiple users and devices can access shared files over the network.
- Automatic Backups: PCs and other compatible devices can regularly back up their data to the NAS.
- Media Server: Photos, music and videos can be stored centrally and accessed from compatible devices.
- Remote Access: Many NAS devices allow secure access to files from outside the local network.
What Network Speed Should a NAS Support?
The speed of your network connection affects how quickly files can be transferred between your NAS and other devices. Many NAS devices feature a Gigabit LAN port. For larger amounts of data or multiple simultaneous users, models with 2.5 Gigabit or 10 Gigabit LAN may be worthwhile. However, the other network components must also support the corresponding speeds.
What Should You Look for When Choosing a NAS?
Besides network speed, the number of drive bays and supported storage features are also important. The right specifications depend on your required storage capacity and intended use.
- Drive Bays: The number of bays determines how many HDDs or SSDs can be installed. Models with multiple bays offer additional storage management options.
- RAID Support: Depending on the RAID level, multiple drives can be combined for improved performance or protection against individual drive failures.
- Processor and Memory: The CPU and RAM affect how well the NAS can handle multiple simultaneous accesses and applications.
- Software: Depending on the model, features such as user management, automated backups, file sharing and media servers are available.
FAQ – NAS
How Do You Connect a NAS to Your Network?
A NAS is usually connected to a router or network switch via an Ethernet cable. Compatible devices on the same network can then access the shared files. Setup is generally carried out through the NAS management interface.
Can I Access a NAS over Wi-Fi?
Yes, devices connected via Wi-Fi can also access a NAS if they have the appropriate network permissions. The NAS itself is normally connected to the router or switch via LAN. Transfer speeds over Wi-Fi depend on factors such as signal strength and the Wi-Fi standard being used.
Does a NAS Need an Internet Connection?
No, an internet connection isn't necessary to use a NAS within your local network. However, features such as remote access, cloud synchronisation or software updates may require an internet connection.
What's the Difference Between a NAS and an External Hard Drive?
An external hard drive is usually connected directly to a device via USB. A NAS, on the other hand, provides storage over the network, allowing multiple devices to access it. Many NAS devices also support features such as automatic backups and individual access permissions.
Do I Need a Special Router for a NAS?
No, for basic use, a router or network switch with a compatible Ethernet port is sufficient. If you want to use higher network speeds such as 2.5 or 10 Gbit/s, the other network components involved must also support these speeds.
