The Multi-Size M.2 NVMe to U.2 (SFF-8639) 2.5” SSD converter/adapter converts an M.2 NVMe module into a U.2 2.5” drive form factor with a thickness of 9.5mm. The casing dimension and U.2 interface are on the same location as a standard U.2 2.5” drive allowing for easy insertion into the U.2 mounting bracket and U.2 rackmount backplane. The unique casing is mill out of Aluminum using the CNC method for excellent heat management; it comes with a thermal pad and the fin-like design on the casing to help dissipate heat. This converter allows for different size M.2 NVMe module 80mm, 60mm, 42mm, and 30mm in length to be fitted into the converter. The converter is hot-swappable* ready and comes with many more features. * Hot-swap requires a Hotswap ready U.2 Host controller.
