Yottamaster 40 Gbps USB4 M.2 NVMe Enclosure with Fan

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.
