Single-Drive NVMe Enclosure with 40 Gbps USB4
The Yottamaster YACOM2 40GBPS-NVME is a one-bay M.2 NVMe enclosure that connects through a USB4 Type-C link rated at 40 Gbps. It accepts M-key SSDs in 2230, 2242, 2260 and 2280 form factors up to 4 TB. An integrated low-noise fan, aluminium shell, bi-directional vents and a silicone thermal pad combine to dissipate heat during sustained workloads. No external power adapter is required.
Who This Suits and Who It Doesn't
Creative professionals moving multi-gigabyte video or audio projects between laptops, desktops, gaming consoles and smartphones will benefit from the tested 2831 MB/s read and 2787 MB/s write speeds on Thunderbolt 4 hosts. Buyers who need to install more than one drive at a time, or who require an external power supply for their SSD, should consider other solutions.
Deciding Specification — 40 Gbps USB4 Interface
The single figure that determines compatibility is the 40 Gbps USB4 connection; the host port must support this bandwidth to reach the quoted transfer rates. If the computer only offers slower USB or Thunderbolt versions, performance will fall proportionally. Verify that the system provides a USB4 or Thunderbolt 4 Type-C port before purchase.

Questions about this item
What M.2 NVMe SSD sizes does the Yottamaster 40 Gbps USB4 enclosure support?
The enclosure accepts M-Key NVMe SSDs in 2230, 2242, 2260 and 2280 form factors, up to a maximum of 4 TB per drive.
Will the enclosure run at full speed when connected to a Thunderbolt 3 port on my older laptop?
Yes, the enclosure is compatible with Thunderbolt 3 and will operate at up to 40 Gbps when the host port supports that bandwidth.
How can I verify the enclosure is delivering the advertised 40 Gbps performance after setup?
Run a sequential read/write benchmark on the installed NVMe SSD; on a Thunderbolt 4 host you should see speeds approaching 2831 MB/s read and 2787 MB/s write.
