Standalone SATA Drive Cloner

This StarTech.com dock duplicates one 2.5 or 3.5 inch SATA drive to another without a host computer. It also functions as a dual-bay USB 3.0 or eSATA enclosure for direct drive access. The JMicron JM562 chipset supports SATA III 6 Gbps and UASP for faster transfers. Ideal for IT technicians creating identical system images or backing up workstation drives.

Suits solo duplication and dual-bay docking

Best for users who need sector-by-sector cloning offline and occasional hot-swap access over USB 3.0 or eSATA. Not suited for workflows requiring more than two simultaneous drive bays. Not suited for environments that rely on interfaces other than SATA, USB 3.0 or eSATA. The dock operates standalone for cloning, then connects to Windows, macOS, Linux or Chrome OS hosts for file access.

Offline clone speed of 22 GB per minute

The key specification is the standalone duplication rate of 22 GB per minute, which determines how long a full drive copy takes. Each bay accepts drives tested up to 4 TB for 3.5 inch 7200 RPM models and 2 TB for 2.5 inch 5900 RPM models. The package includes USB 3.0 cable, eSATA cable, universal power adapter and manual.

Questions about this item

How do I install a 3.5 inch SATA drive into the dock, and what step do people often miss?

Slide the drive into a bay until the SATA data and power combo connector seats fully; the step often missed is connecting the universal power adapter before pressing the clone button.

What maintenance or replacement will the SDOCK2U33RE need later?

The USB 3.0 cable, eSATA cable, or universal power adapter may wear out and need replacing; the dock itself has no moving parts or user-serviceable components.

What limit appears first during sustained cloning at the rated 22 GB per minute speed?

The source or target drive's own sustained transfer rate and thermal throttling will limit actual throughput before the JMicron JM562 chipset or SATA 6 Gbps interface does.
