Asustor As5004U NAS

ASUSTOR AS5004U 4-Bay USB 3.2 Gen 2 Storage Expansion Unit

Effortlessly expand the storage capacity of your ASUSTOR NAS with the AS5004U, a powerful 4-bay expansion unit designed for seamless integration and high-speed performance. As your data needs grow, from high-resolution media collections to critical business backups, the AS5004U provides a simple, scalable, and secure solution. Avoid the complexity of migrating to a larger NAS; simply connect the AS5004U to your existing ASUSTOR device and instantly add massive storage potential.

Engineered for speed, the AS5004U utilizes a USB 3.2 Gen 2 Type-C connection, delivering blazing-fast transfer rates of up to 10Gbps. This ensures that accessing files, streaming media, or running backups from the expansion unit feels just as responsive as using your NAS´s internal drives, eliminating performance bottlenecks. The unit is designed to keep pace with demanding workflows, making it ideal for content creators, data-heavy businesses, and media enthusiasts.

One of the standout features of the AS5004U is its full support for ASUSTOR´s revolutionary MyArchive cold backup technology. This turns the hard drives within the expansion unit into removable, archivable storage collections. Create multiple MyArchive drives for different projects, clients, or backup cycles. When not in use, you can store them offline, providing an air-gapped layer of security against ransomware and other digital threats. It´s the ultimate solution for long-term, secure data preservation, offering virtually unlimited storage possibilities.

The AS5004U is intelligently designed for both energy efficiency and hardware longevity. Its smart power synchronization mechanism links its power state directly to the host NAS. When your NAS enters sleep mode or shuts down, the AS5004U follows suit, significantly reducing power consumption and saving on energy costs. Furthermore, a dedicated smart fan control system constantly monitors drive temperatures, adjusting its speed to ensure optimal cooling. This not only protects your valuable hard drives from overheating but also maintains quiet operation, making it suitable for any home or office environment. Its tool-less design and hot-swappable drive trays ensure that adding or replacing drives is a quick and straightforward process.
