The WD My Book Duo with 2 x 2TB hard drives configured in mirroring mode (RAID 1) offers a reliable and secure way to store important files, photos, videos, and backups. In this setup, the system uses two drives to create an exact copy (mirror) of your data, ensuring that even if one drive fails, your files remain safe and accessible.

🔐 What is Mirroring (RAID 1)?

RAID 1 mirrors data across both drives. If you store a 1GB file, it's saved simultaneously on both drives. The key benefit is data redundancy—you won’t lose your files if one of the drives becomes corrupted or fails. However, this comes at the cost of storage space: with 2 x 2TB drives, you’ll get only 2TB of usable space, not 4TB.

⚙️ Setup & Configuration

The WD Discovery software lets you easily configure your My Book Duo. During setup, choose RAID 1 (mirroring) for maximum data protection. You can also switch to RAID 0 if you prefer full capacity and faster performance—but keep in mind it offers no redundancy.

💡 Who Should Use Mirroring?

Mirrored RAID is ideal for users who prioritize data safety over storage size—like photographers, business professionals, and anyone storing irreplaceable data. It acts like a real-time backup, giving you peace of mind.

✅ Final Thoughts

The My Book Duo with 2 x 2TB drives in mirroring mode is a solid, plug-and-play storage solution. It combines Western Digital’s reliability with built-in data protection, making it perfect for anyone who can’t afford to lose important files.
