?Easy to use? NGFF/NVME compatible. Comes with screws and screwdriver, easy to install M.2 NVME and NGFF (SATA), easy to use and portable. ?Heat Dissipation Design?PCBA board surface is processed with copper rod to prevent abnormal heat generation of the product. Heat dissipating silicon based chip design is used. In addition, a heat dissipation silicone patch is included to effectively prevent excessive temperature. ?4TB large capacity?Up to 4TB SSD can be installed. backward compatible with USB3.0/USB2.0 interface, read speed: 1000MB/s (This data is for reference only). Compatible with Windows 11/10/7/Mac OS/Linux systems. ?High Speed & Stability?The m2 usb adapter external output port is USB3.1 GEN2 USB Type-A. The theoretical transfer speed is 10Gbps for NVME protocol and 5 Gbps for NGFF protocol, with a substantial increase in read speed and a rise in transfer speed for large files, using RTL9210B chip with UASP and TRIM functions. Reduced CPU load, lower consumption, faster speed and higher durability. ?Compatible with M.2 NVME and NGFF (SATA)?Eluteng m.2 to usb adapter, corresponds to two different hard drives. It supports M.2 NVME or NGFF (SATA) in 2230/2242/2260/2280mm sizes. Compatible with B-key, M-key and B+M-key. Meet the needs of different scenarios and save time, effort and money by eliminating the need to deploy two additional hard drives! Note: PCI-E AHCI protocol is not supported.
