40Gbps USB4 NVMe Enclosure

The Yottamaster YRM2 40GBPS-NVME is a silver aluminum and plastic enclosure that accepts M-key M.2 NVMe SSDs in 2230, 2242, 2260 and 2280 sizes. It supports drives up to 4TB and connects via a USB4 interface rated at 40Gbps. A low-noise fan, bi-directional vents and a silicone thermal pad provide active cooling for sustained workloads.

Suits users needing portable high-speed NVMe storage

This enclosure suits users who want tool-free SSD swaps and 40Gbps transfer potential on Thunderbolt 4 or USB4 hosts. It is not for buyers with B-key M.2 drives or those requiring an included AC power adapter for bus-powered operation limits.

40Gbps USB4 interface with 2-in-1 cable

The decisive specification is the USB4 40Gbps interface paired with an included 2-in-1 cable offering USB-C to C at 40Gbps and USB-C to A at 10Gbps. Tested read and write speeds reach 2831 and 2787 MB/s respectively on Thunderbolt 4 laptops.

Questions about this item

Which M.2 NVMe SSD lengths does the Yottamaster enclosure accept?

The enclosure supports M-Key NVMe SSDs in 2230, 2242, 2260 and 2280 sizes, up to 4 TB capacity.

Will the 40 Gbps USB-C to C cable work with a Thunderbolt 3 port on my laptop?

The USB4 cable is compatible with Thunderbolt 3 hosts, but the 40 Gbps link requires a Thunderbolt 4 or USB4 port; on Thunderbolt 3 it will negotiate a lower speed.

How can I verify the enclosure is delivering the advertised 40 Gbps performance after setup?

Run a sequential read/write benchmark such as CrystalDiskMark on the attached SSD; on a Thunderbolt 4 host you should see speeds approaching 2831 MB/s read and 2787 MB/s write.
