KingDian SSD’s NVME PCIe Gen4x4 Series is an advanced external storage device that uses the NVME (non-volatile memory express) protocol and the PCIe (peripheral component interconnect express) interface to achieve ultra-fast data transfer rates up to 5100MB/s. This is up to 10 times faster than normal external HDD (hard disk drive), which means that users can enjoy faster boot times, shorter loading times, and smoother performance. KingDian SSD’s NVME PCIe Gen4x4 Series is compatible with most devices that support PCIe Gen4x4 or lower.
