Before you buy — compatibility
This dock works only with 2.5-inch and 3.5-inch SATA drives; it does not accept M.2, NVMe or mSATA drives. It connects to the computer over USB-A (not USB-C) and requires its external power adapter, so it is not bus-powered. For one-touch cloning, the target drive must be the same size as or larger than the source. The interface is USB 3.2 Gen 1x1 (5 Gbps).

Frequently Asked Questions
Does the LC-DOCK-U3-VI work with M.2 or NVMe SSDs?
No. It is built for 2.5-inch and 3.5-inch SATA HDDs and SSDs only. For M.2 NVMe or SATA SSDs you need an M.2-specific dock or enclosure instead.
Can it clone a drive without a computer?
Yes. Place the source drive in one bay and a same-size or larger target in the other, then press the clone button for a sector-by-sector copy including the boot partition. No PC required.
Does it need an external power supply?
Yes. Because it powers two 3.5-inch drives, it uses the included external mains adapter and is not bus-powered. It connects to the computer over USB-A.
What should I know before buying the LC-DOCK-U3-VI?
It is SATA-only (no M.2), connects via USB-A at USB 3.2 Gen 1x1 (5 Gbps), supports drives up to 20 TB per slot, and the drives are sold separately. For cloning, the target must be equal or larger than the source.
Singular Expert Insight
For SATA drives, a dual-bay dock like the LC-DOCK-U3-VI is the most flexible choice: it clones offline and lets you mount two drives at once, unlike single-bay docks such as the LC-DOCK-U3-V. If you mainly work with modern M.2 NVMe drives instead, look at a dedicated M.2 dock; and for finished backups you simply leave on the shelf, a complete
external hard drive is more convenient than a bare drive plus dock.
Buyer’s Guide
Buy it if
You regularly clone, back up or swap 2.5-inch and 3.5-inch SATA drives and want PC-free one-touch cloning with two bays and up to 20 TB per slot.
Skip it if
You need M.2/NVMe support, a bus-powered USB-C dock, or speeds above 5 Gbps. This unit is SATA-only, USB-A and needs an external adapter.
Also consider
The single-bay LC-DOCK-U3-V if you only need one drive, or an M.2 NVMe dock if your drives are modern PCIe SSDs.
