M.2 PCI-E 3.0 SSD laptops
PCI-E 3.0
— 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 3.0 provides speeds of about 1 GB/s per line. PCI-E 3.0 comes in 2 and 4 lines, respectively, two lines give 2 GB / s, four — 4 GB / s.Show
