NAS devices connect to your network via Ethernet or Wi-Fi, creating a local area network (LAN). They use file-sharing protocols like NFS and SMB/CIFS to allow multiple users to access stored data simultaneously. See more: How Does NAS Work?

RAID (Redundant Array of Independent Disks) is a technology that combines multiple drives for improved performance and data protection. It's crucial for ensuring data redundancy in NAS systems.

NAS-specific hard drives, such as WD Red or Seagate IronWolf, are recommended for their reliability and performance in always-on, multi-user environments. For more, check out: What Drives Should I Use for a NAS?

NAS storage devices come in various capacities, typically ranging from a few terabytes to hundreds of terabytes, depending on the model and number of drive bays. For example, the UGREEN NAS series offers storage capacities such as 76TB, 136TB, 196TB, and 256TB.

Yes, you can access your NAS storage remotely through several methods, each with different levels of security and ease of use:

VPNs

Most secure method using either built-in NAS VPN services or router VPN capabilities.

• Pros: Highest security level
• Cons: More complex setup

Port Forwarding

Direct connection method that requires router configuration.

• Pros: Fastest connection speeds
• Cons: Requires technical knowledge, potentially less secure if not properly configured

The best method depends on your needs: choose VPN for security, or port forwarding for speed.
