18 TB portable storage for Windows and Mac

The Avolusion PRO-G1 18TB drive connects through USB 3.2 Gen 2 and adds massive capacity to desktops or laptops without opening the case. It is aimed at users who need large local backups or media libraries and want a single, bus-powered device that works on both operating systems.

USB 3.2 Gen 2 caps real-world throughput at 10 Gbps

The interface limits sustained transfer rates well below the internal 7200 RPM drive's potential. Older USB 3.0 ports will drop performance further, and the connection cannot saturate the mechanical disk during large sequential workloads.

18 TB raw capacity yields about 16 TB after

That space comfortably holds extensive photo, video and document archives for most creative or office workflows. Very large uncompressed media projects or multi-year backup histories may eventually exceed the available headroom.

Questions about this item

How do I decide between the 18 TB model and smaller capacities in the PRO-G1 series?

The 18 TB version delivers the maximum raw space in the line; after formatting you can expect roughly 16 TB usable, so choose it when you need the largest single-volume backup target.

What does the 10 Gbps headline speed actually deliver when the drive is connected to my PC?

The 7200 RPM mechanism limits sustained throughput well below the 10 Gbps interface ceiling, so real-world copy rates will be those of a conventional 7200 RPM hard drive rather than the full bus potential.

What does USB 3.2 Gen 2 mean for compatibility and the practical speed limit?

The drive uses a USB-C 3.2 Gen 2 connection rated at 10 Gbps and works with USB 3.0 ports, but the mechanical 7200 RPM drive inside sets the actual transfer ceiling, not the interface.
