— connection via PCI-E interface using 1 line (data link).PCI-E is the main modern interface for connecting expansion cards to the motherboard. And on the one hand, the data transfer rate depends on the number of lines, on the other hand, the connection features: the more channels, the faster this version of PCI-E and the larger the connector it will need. Accordingly, PCI-E 1x is the smallest and slowest variation of this interface: the data transfer rate through this connector is slightly less than 1 GB / s per line in PCI-E 3.0 version and slightly less than 2 GB / s per line for PCI-E 4.0. Such speeds are quite suitable for many expansion cards (see "Type"), however, they are considered insufficient for RAID controllers.
