1、HEAT DISSIPATION: USB4.0 M.2 NVMe external SSD enclosure is made of full aluminum alloy body with silicone grease sticker, heat conducting aluminum sheet, metal heat conducting groove process refuses to get hot easily export heat to solve the problem of the hard drive dropping speed due to heat. 2、EASY TRANSFER: The use of piston screws to facilitate the hard disk more closely to the shell, the hard disk heat quickly exported to the shell. 1 second easy transfer 3000MB/S, support for single disk expansion of large capacity hard disk. 3、USB4.0 CORE CONTROL: USB4.0 M.2 NVMe solid state drive enclosure adopts USB4.0 core control, which is widely compatible and the speed is 4 times faster than USB3.2 Gen2 and 8 times faster than USB3.0. With USB4 Type C interface, data transfer rate up to 40Gbps. 4、STURDY AND DURABLE: USB4.0 M.2 NVMe solid state drive case is made of low density, high strength aluminum alloy, CNC precise cut and anodized for durability. Tool free installation, press ball snap one piece molding. 5、EASY TO CARRY AND STORE: USB4.0 M.2 NVMe SSD enclosure is not only portable, but also storable, comes with a hiking buckle, compiled with an organizer strap to wrap the data cable around it. Storage is more convenient to use, not easy to lose the line more convenient storage. 6、PLUG AND PLAY: Type C downward compatible with USB3.2/3.1/3.0/2.0 (USB port requires an adapter or need to purchase a line to use), plug and play, drive free, seamlessly connecting more devices system use.
