It is for Lenovo computer disassembly, with light reading and writing. Does not support MAC OS. To purchase this product, please make sure that the motherboard supports PCI E NVME 3.0 X4 interface. Some motherboards only support PCI E 2.0, and the hard disk speed cannot be fully utilized. By default, the system for WIN10 requires us to check "shut down the system to refresh the Windows10 write cache on the device" in the device manager to obtain a relatively normal read and write speed. The above motherboard/laptop does not support the installation of this solid state, and there is no default driver in the system for WIN7, so when the system for WIN7 and the system for PE are installed, the hard disk may not be found.
