NAS

1. What is NAS?

• A NAS is a type of file storage device connected to a computer network.
• It usually contains several drives designed to hold databases, system images, and backup files in a central location.
• The stored data is always available to multiple users, who can then access it at the same time.

2. How does NAS connect to a network?

• First, connect NAS to your local area network (LAN).
• If you have a Wi-Fi router, connect the NAS to an Ethernet port on the router.
• If using Ethernet, it's possible to connect NAS to a network hub or switch. The NAS device has its own IP address on your network.

3. Does NAS require Internet connection?

• High-capacity network connectivity is essential for busy NAS devices in enterprise data centres.
• NAS designed for smaller, less-demanding environments can get by with Wi-Fi connectivity, while small NAS devices for end-users might supply a USB port for direct PC connectivity.

4. Can you access NAS from different network?

• If you have a Synology NAS, it's actually quite easy to access your NAS from outside of your home network: Go to Control Panel > External Access > QuickConnect. Check the Enable QuickConnect box. Enter your preferred ID in the QuickConnect ID box.

5. Is NAS only on a local network?

• A NAS device is designed to be used within a local network, allowing users on the same network to access shared files and data.
• By default, most NAS devices are configured to work within a local network and are not accessible from the internet.

6. Does a NAS need a firewall?

• Most NAS devices have built-in firewalls, so there's no reason to turn them off, even if perimeter firewalls and other security measures already protect the network.
• Since NAS devices contain privileged information and data, ensure multiple layers of security protect them.

7. How many drives do you need for a NAS?

• Three drives are the minimum for RAID 5, which can survive the loss of one drive, though four drives are a more common NAS system configuration.
• Five drives allow for RAID 6, which can survive the loss of two drives.

8. How long can NAS storage last?

• Every time data is written to the drive, it wears down a little bit. So, if you write a lot of data to the SSD frequently, it will wear out faster.
• On average, SSDs last for around 3 to 5 years, but some can last up to 10 years or more.

9. Can a NAS run as a server?

• Yes, ASUSTOR NAS drives can be used as servers for various applications. ASUSTOR provides a variety of built-in server applications for their NAS drives, including file servers, media servers, web servers, database servers, and more.

10. Can I connect a NAS directly to my computer?

• You can use an ethernet port on the NAS that has a static IP address, but you should use the same IP range on the PC.
• Once you log in, you can transfer data almost 10x faster compared to a 2.4GHz Wifi Router.

11. What is the most secure way to access NAS?

• Accessing your NAS remotely is made easy with QNAP's myQNAPcloud link and doesn't require opening any ports.
• This is the most secure and straightforward way to remotely access your NAS.

Reference


12. What is the speed of NAS storage?

• Data transfer speeds for NAS devices typically fall in the 3 – 20MB/s range for consumer-level devices and up to about 110MB/s for high-end, modern NAS devices.

13. What happens if a NAS drive fails?

• A NAS device does not need to be physically present on the server but can exist anywhere within the network.
• If you experience failed NAS servers or NAS failures, then through NAS Data Recovery, you can resume the working condition of the server.
