Two-Bay SATA Dock with Offline Clone

The MAIWO K3072 is a dual-bay enclosure that accepts 2.5 and 3.5 inch SATA hard drives and SSDs. It connects to a host via USB 3.0 and includes a 12V/3A power adapter for desktop operation. The tool-free design lets you swap drives without screws or drivers. It suits users who need quick access to bare SATA drives for backup or data recovery.

Offline One-Key Clone Function

A dedicated clone button copies data from the source bay to the target bay without a computer attached. The dock supports drives up to 20TB each, giving a combined 40TB potential capacity. This hardware-level duplication works sector-by-sector and is independent of file system or operating system. It is not for users who require software verification or incremental imaging.

UASP-Accelerated Sustained Transfer

With UASP protocol enabled, the USB 3.0 interface moves large sequential workloads at up to 5Gbps, reducing CPU overhead during long copies. The plastic chassis provides passive cooling for both drives during extended clone or transfer sessions. It is not for workflows that demand 10Gbps NVMe speeds or active cooling under continuous maximum throughput.

Questions about this item

What does the 40 TB expansion figure mean when the dock is connected to a PC?

The dock can address up to 20 TB per bay, so two drives give a combined 40 TB of usable storage once the host OS recognises both volumes.

Which external interface standard limits the transfer rate, and what speed does it cap at?

USB 3.0 (5 Gbps) is the external link; with UASP enabled the practical ceiling is the bus's 5 Gbps signalling rate.

What physical drive sizes and mounting style does the enclosure accept?

Tool-free trays take any 2.5-inch or 3.5-inch SATA HDD or SSD up to 20 TB each, no screws or caddies required.
