SAS Dock for Enterprise Drives

The MAIWO K308SAS is a single-bay USB 3.0 docking station built for 2.5-inch and 3.5-inch SAS and SATA hard drives or SSDs up to 18TB. It targets IT engineers and technicians who need to read, copy or diagnose server-grade storage without installing it inside a chassis. The vertical dock holds the drive securely and operates driver-free on Windows, Linux and Mac OS.

Plug-In Simplicity with Dedicated Power

A supplied 12V/2A adapter delivers 24W to spin up high-capacity enterprise drives that a USB port alone cannot sustain. The USB Type-B to Type-A cable connects to any USB 3.0, 2.0 or 1.1 port for backward compatibility. Hot-swap support lets you swap drives without rebooting, while an LED shows power and data-access status at a glance.

Steady Throughput for Long Transfers

The USB 3.0 interface caps sustained transfer rates at 5Gbps, dropping to 480Mbps on USB 2.0 links. Because the dock has no fan, the open vertical design relies on passive airflow around the drive casing during extended copy sessions. It is not suited for RAID arrays or multi-drive workflows that demand simultaneous access to more than one disk.

Questions about this item

How many drives can the K308SAS dock accept at once?

The dock has a single bay, so only one 2.5 or 3.5 inch SAS or SATA drive can be inserted at a time.

Does the adapter generate noticeable heat or noise during continuous operation?

There is no built-in fan; the vertical open design relies on passive airflow around the drive to dissipate heat during extended use.

What cables and power supply are required before the dock will work?

The package includes a 12V/2A power adapter and a USB Type-B to Type-A cable, so no extra items are needed to start.
