Dual-Bay SATA Dock for 2.5" and 3.5" Drives

The Wavlink WL-ST334U accepts two SATA I/II/III hard disks or SSDs up to 8TB each. It connects through USB 3.1 Gen 1 and includes a USB-C adapter for modern laptops. Offline cloning runs without a host computer and progress is shown by four LED indicators. The unit is aimed at technicians and archivists who need quick, tool-free access to bare drives.

Offline Clone Requires Larger Target Drive

Cloning starts with one button press and copies at up to 60Mbps. The target drive must be equal to or larger than the source drive, and the function works only while the dock is disconnected from a PC. No driver installation is needed for the dock itself on Windows, macOS or Linux.

UASP Protocol Sustains Higher Throughput

With UASP enabled the dock reaches 6Gbps over the internal SATA link, about 20% faster than standard USB 3.0 bulk endpoints. The 12V 3A power adapter keeps both bays spinning steadily during long imaging or recovery sessions. Housing is ABS plastic measuring 5.51" x 4.72" x 2.95".

Questions about this item

What does the 6 Gbps UASP figure mean when the dock is connected to my PC?

With UASP enabled the dock can move data at up to 6 Gbps between a SATA drive and the host, which is roughly 20 % faster than standard USB 3.0 bulk endpoints.

The dock uses USB 3.1 Gen 1 at 5 Gbps — what does that cap in practice?

The USB 3.1 Gen 1 link tops out at 5 Gbps, so even though the internal SATA bus can do 6 Gbps the external connection limits sustained throughput to the 5 Gbps ceiling.

What do I need to fit a 3.5-inch drive into either bay?

Each bay accepts 2.5-inch or 3.5-inch SATA drives directly with no tray or caddy required; just slide the drive in and connect the dock to power.
