Avolusion PRO-H1 20TB Desktop External Drive

The Avolusion PRO-H1 is a desktop external hard drive that holds 20TB on a 3.5-inch 7200 RPM enterprise drive with a 256MB cache. It connects through a USB 3.2 Gen 2 port running at 10Gbps and is backward compatible with USB 3.0. The fan-less chassis keeps operation silent while the drive is designed for 24/7 use.

Suits backup and expansion.

This drive suits users who want to add large-capacity backup or media storage to a Windows PC, Mac or Xbox without opening the case. The exFAT pre-format works across platforms, though the console requires a reformat. Buyers who need a rugged, bus-powered drive for frequent travel should look elsewhere, as this unit requires its own power supply and is built for stationary desktop use.

USB 3.2 Gen 2 (10Gbps) interface decides fit

The single specification that determines compatibility is the USB 3.2 Gen 2 interface delivering up to 10Gbps. Your host must provide a USB 3.2 Gen 2 or USB 3.0 port and enough power for a 3.5-inch desktop drive. If your system only offers USB 2.0 or lacks a suitable power adapter, the drive will not perform as intended.
