Good to know

The enclosure is bus-powered, so no separate power supply is needed—just plug it into a USB-C port. For maximum speed, connect to a USB 3.2 Gen 2 port; it is backward compatible with USB 3.0 and USB 2.0. The aluminum body not only looks premium but also helps dissipate heat during sustained transfers. A 0.5 m USB-C to USB-C cable is included; if your host device only has USB-A, you'll need a separate adapter or cable.
