Thank you! _x005f_x000D_ Please allow 1-2cm measuring deviation due to manual measurement. _x005f_x000D_ _x005f_x000D_ Included: _x005f_x000D_ 1 * Hard disk box _x005f_x000D_ 1 * Instructions _x005f_x000D_ 1 * Connecting line 1. Mobile Storage: M.2 SSD solid state hard disk becomes mobile hard disk in seconds. Connecting to Type-C mobile phone can massively expand large file photos, connecting to Type-C compatible with ipad can massively store more high-definition movies online. 2. 1G File Transfer in 1 Second: M.2 to USB3.1GEN2, the theoretical transmission speed is 10Gbps, and the measured reading and writing speed can reach about 1000MB/S. The RTL9210B is used as the main control chip to carry the NVME PCI-E 3.0 protocol, and the performance is very good. 3. Tool-free Installation Design: The opening and closing design is easily completed by one pressing and one pulling! The hard disk is fixed with silicone screw posts, which is convenient and stable! 4. Rapid Heat Dissipation: aluminum alloy shell and metal heat sink, long-term use, can quickly dissipate heat from the hard disk and ensure the stable operation and transmission of the hard disk.
