M.2 PCI-E 4.0 SSD laptops
PCI-E 4.0
— universal interface for connecting internal peripherals. Provides generally faster speeds than SATA, making it better suited for SSD modules: theoretically, PCI-E allows you to realize the full potential of SSDs, even the fastest. In fact, the supported data transfer rate may be different — depending on the version of the interface and the number of lines (data transmission channels). Version 4.0 provides speeds of about 2 GB/s per line. Accordingly, PCI-E 4.0 on four lines provides speeds up to 8 GB / s.Show
