External HDD Western Digital My Book Duo 24TB Black, RAID-capable desktop storage (WDBFBE0240JBK)

The Western Digital My Book Duo 24TB is a desktop external HDD solution designed to provide large-capacity local storage for backups, multimedia libraries and archived project files. The black chassis houses two mechanical drives in a single enclosure and supports configurable RAID modes that prioritise either performance or data redundancy. Connectivity to a PC is provided for mass storage, and bundled management software enables basic drive management and backup scheduling.

Advantages

This My Book Duo model offers high usable capacity in a compact desktop form factor while allowing RAID configuration for either improved throughput or mirror protection. The dual-drive design simplifies managing large multimedia collections and long-term archives without requiring internal drive installation. Native compatibility with standard file systems and bundled utilities helps with scheduled backups and drive monitoring.

Suitable for

• Local backups of PCs and workstations
• Storing large photo, video and audio libraries
• Content creators and small studio workflows needing high-capacity storage
• Archiving project files and long-term data retention

When it may not be suitable

The My Book Duo is a desktop-attached drive intended for local use and not for direct network-attached deployment; it requires a host PC for access rather than offering built-in NAS services. It uses mechanical hard drives, so access times and sustained transfer rates will be lower than those of SSD-based solutions, and it is not designed for environments that demand very high IOPS or ultra-low latency.

Key specifications

• Total raw capacity: 24 TB (combined from two internal drives)
• Drive type: 3.5-inch SATA mechanical hard drives inside the enclosure
• RAID modes supported: software/firmware-configurable modes for performance (striping) or redundancy (mirroring)
• Interface to host: high-speed USB connection for desktop PCs (cable included)
• Form factor: vertical desktop enclosure with external power supply
• Management: included utilities for backup scheduling and drive management

How to use

Connect the My Book Duo to a compatible PC using the supplied USB cable and power adapter. Use the included software to select the preferred RAID configuration or set up the drives as separate volumes if desired. Configure scheduled backups through the bundled application or use your preferred backup software to copy files and folders to the drive. For large file transfers, allow time for initial data seeding and ensure the host system remains powered and awake until transfers complete.

What to consider before purchase

• Whether you prefer RAID for performance (striped) or redundancy (mirrored) and how that affects usable capacity
• Need for local desktop storage versus networked (NAS) access
• Compatibility with your operating system and backup software
• Physical space and power availability for a desktop enclosure

Usage recommendations

For data protection, enable a mirrored RAID configuration if redundancy is important, and maintain an offsite backup in addition to the My Book Duo. Periodically check drive health using the included management tools and keep firmware and software up to date. Use the unit on a stable surface with adequate ventilation to help maintain optimal drive temperatures during heavy transfers.
