Capacity and interface

The Avolusion PRO-H1 is a 4 TB portable hard drive that connects through a USB 3.2 Gen 2 port running at 10 Gbps. It uses a 7200 RPM enterprise-class drive with 64 MB cache and is pre-formatted in exFAT for immediate use on Windows, macOS or Xbox consoles. The white chassis houses a fan-less design for silent operation.

Ready-to-use formatting

The drive arrives formatted in exFAT so it works across Windows, macOS and Xbox without extra software. Xbox consoles require a quick re-format before storing games, while PCs and Macs can read and write straight away. No drivers or backup utilities are bundled; the hardware itself is the complete package.

Enterprise drive headroom

The internal 7200 RPM enterprise drive is rated for 24/7 operation and tested at 100 % health with zero bad sectors. It handles continuous backups, large media libraries and game installs comfortably. Sustained throughput is limited by the mechanical spindle and the USB 3.2 Gen 2 link, so workloads demanding SSD-class random access will saturate the drive.

Questions about this item

Will the internal enterprise drive need replacement after continuous 24/7 operation?

The drive is built for 24/7 use with zero bad sectors and 100% health at factory test, so no scheduled replacement is required under normal conditions.

What limits sustained write speed when the drive runs at full load?

The 7200 RPM spindle and 64 MB cache set the mechanical ceiling, while the USB 3.2 Gen 2 link caps throughput at 10 Gbps.

How much noise and heat does the fan-less enclosure add during all-day use?

The silent fan-less chassis keeps acoustic output minimal; heat dissipation relies on the metal case surface, so the drive stays quiet even under continuous load.
