Dual-Bay M.2 NVMe Enclosure

The Wavlink ST348 holds two M.2 PCIe NVMe or AHCI drives up to 8 TB each. It connects to Windows, macOS, Linux, Chrome OS, Android, Harmony OS, iPadOS and iOS devices through a USB-C or USB-A port and includes an offline cloning function that copies data from the source drive to the target drive without a computer.

USB 3.2 Gen 2 20 Gbps Interface

The USB-C connection tops out at 20 Gbps with quoted sequential reads of 1631 MB/s and writes of 1267 MB/s. Real-world speed depends on the host controller, cable quality and the SSD itself. The enclosure will not work with SATA or mSATA M.2 drives and the target disk must be larger than the source when cloning.

Tool-Free Assembly with Cloning Steps

A sliding cover opens without tools; two thermally conductive silicone pads and silicone buckles secure 2230, 2242, 2260 and 2280 drives. Cloning only starts after the data cable is unplugged and the clone button is held; inserting the drives in the wrong bays prevents the operation. A 5 V/4 A power adapter is required for stable operation.

Questions about this item

Should I pick one 8 TB NVMe stick or two smaller drives for this dual-bay enclosure?

Each bay accepts up to 8 TB, so a single 8 TB drive works in one slot while the second bay stays empty, or you can populate both bays with smaller NVMe SSDs such as 2230, 2242, 2260 or 2280 sizes.

What do the quoted 1631 MB/s read and 1267 MB/s write speeds mean when the enclosure is connected to my laptop?

Those are the measured sequential transfer rates through the USB 3.2 Gen 2 Type-C link; actual throughput will match these figures only if the host port also supports 20 Gbps and the installed NVMe SSD can sustain equivalent speeds.

The box says USB 3.2 Gen 2 Type-C at 20 Gbps — what does that cap in everyday use?

The 20 Gbps interface sets the maximum data rate between the enclosure and the host, so combined read and write traffic cannot exceed this bandwidth regardless of how fast the individual NVMe drives are.
