— universal interface for connecting internal peripherals. It generally provides higher speeds than SATA, making it better suited for SSD modules: theoretically, PCIe allows for achieving the full potential of solid-state drives, even the fastest ones. In practice, the supported data transfer speed can vary depending on the interface version and the number of lanes (data transmission channels). Version 3.0 provides a speed of about 1 GB/s per lane. PCIe 3.0 can have 2 or 4 lanes, providing 2 GB/s and 4 GB/s, respectively.
