UGREEN CM400 (#10902) M.2 NVMe SSD Enclosure, USB 3.1 Gen 2 10Gbps, M-Key

The UGREEN CM400 (10902) is an M.2 NVMe SSD enclosure — a case that turns a bare internal SSD into a fast external drive over USB-C. It is the practical way to reuse the drive left over after a laptop or desktop upgrade, and the quickest route to portable storage that behaves like an internal disk rather than a slow external one. The interface is USB 3.1 Gen 2 over USB-C at 10Gbps, with NVMe 1.3 protocol support plus UASP, TRIM and S.M.A.R.T. monitoring, so the drive reports its own health and holds performance through sustained transfers instead of collapsing part way through a large copy. It accepts M-Key and M+B Key NVMe drives in 2230, 2242, 2260 and 2280 lengths, up to 2TB. Installation is tool-free and screwless: the shell opens, the drive slots in, and the aluminium alloy body doubles as a heatsink for the drive inside. A USB-C data cable is included in the box. It earns a place in the bag of anyone who moves large files between machines — video footage, project archives, design files, virtual machine images or a bootable working drive carried between office and home. In a humid climate the sealed metal shell also treats the drive better than a plastic caddy would. It carries a one year warranty.
