【40Gbps Ultra High Speed】USB 4.0 ASM2464PD chipset supports USB-C(USB Type-C) connection and data transmission speed up to PCIe 4.0 x4 40Gbps for steady and efficient data transfer. Compatible with Thunderbolt 4/3 and backward compatible with USB 3.2/3.1/3.0/2.0 at respective speed limits. (Please be sure to use USB 4.0 or Thunderbolt 4 interface and upgrade the OS build and NVM FW version to the lastest version to achieve 40Gbps transfer speed. Backward compatibility will limit the speed, and the device might not be recognized.) | 【Efficient Heat Dissipation】The combination of active heat disspation with built-in cooling fan and passive heat disspation with copper heatpipe and aluminum heatsink helps dissipating the heat generated by M.2 SSD. Effectively protect your SSD from overheating and keep high transfer rate. | 【Optimal Cooling】Highly optimised 30mm fan with low-noise adaptor for ultra-quiet operation would find the balance between the cooling performance and noise level. This cooling fan reduces the heat of M.2 SSD by 60%. Better heat dissipation, less strain on his M.2 SSD when working. | 【Direct Touch Heatpipes】Dual copper heat pipes provides better cooling performance by using DTH(Direct Touch Heatpipes) technology. Its flat machined surface touches the SSD evenly and conducts heat extremely fast. | 【Stability and Safety】NVMe PCIe reader adopts an advanced ASM2464PD controller that built with short-circuit, over-current and multi-protection to ensure safety for your SSD and valuable data.
