Two-bay SATA dock for 2.5" and 3.5" drives

The Wavlink 334U-BL is a USB 3.0 docking station that holds two SATA hard drives or solid-state drives simultaneously. It accepts both 2.5" and 3.5" form factors without tools and connects to a host via a USB-B port. An included 12V 3A power adapter drives both bays, and the unit enters automatic sleep after 30 minutes of inactivity.

Suits technicians and archivists who swap bare

The dock is built for environments where drives are inserted and removed frequently, such as data recovery, imaging or testing workflows. It is not suited for users who need a permanent, sealed enclosure for a single drive or who require RAID functionality between the two bays. Buyers who want hardware encryption or network-attached access should look elsewhere.

Offline clone function copies drive to drive

A dedicated clone button starts a sector-by-sector copy from the source bay to the target bay while LEDs show progress at 25, 50, 75 and 100 percent. The target drive must be equal to or larger than the source, and the process runs at up to 60Mbps without any computer connected. This hardware-only clone mode is the feature that determines whether the dock fits a workflow.

Questions about this item

Does the dock need its own power supply to run two 3.5-inch drives?

Yes, the unit ships with a 12 V 3 A DC adapter that must be connected for 3.5-inch drives to spin up.

Will my older USB 2.0 laptop still recognise the dock?

The dock falls back to USB 2.0 at 480 Mbps and USB 1.1 at 12 Mbps, so it will appear on legacy ports.

How do I know the offline clone finished without a PC attached?

The four clone LEDs light in sequence — 25 %, 50 %, 75 %, 100 % — and the 100 % LED stays solid when the copy is complete.
