Feature: 1. Dual Protocol: Supports M.2 and M.2 NVME drives up to 30TB . Due to longer box design, it has better compatibility with disks and supports SSD size 2230/2242/2260/2280. it supports M Key and B+M Key. 2. High Speed: The maximum bandwidth of M.2 drive can up to 6Gbps, while the maximum bandwidth of M.2 NVME drive can up to 10Gbps. The output speed depends on the type of SSD you are using. 3. Easy to Use: Tool less design, plug and play. You can use to connect a computer or laptop with USB3.2 interface and Type C interface supports to connect a cell phone (your cell phone should support OTG function). 4. USB3.1: Theoretical transfer speed up to 10Gbps, rate M.2 NGFF according to the actual shall prevail, protocol speed limit shall prevail, the product for the adapter box, the hard disk state is good or bad and the protocol of different speeds are different, the speed of the PCIe protocol will be relatively fast, the latest high speed USB3.1 transmission interface, while downward compatible with the USB1.1/2.0/3.0. 5. Lightweight: With slim design and aluminum alloy casing, the hard drive casing is very light weight. The casing can protect your disk well. And it has good heat dissipation performance.
