— universal interface for connecting internal peripherals. Generally provides higher speeds than SATA, making it better suited for SSD modules: theoretically, PCIe allows for the full potential of solid-state drives, even the fastest ones. In practice, the supported data transfer rate can vary depending on the interface version and the number of lanes (data channels). Version 4.0 ensures a speed of about 2 GB/s per lane. Accordingly, PCIe 4.0 with four lanes provides a speed of up to 8 GB/s.
