More connectivity options
Z170 also has a far more flexible selection on of High-speed Input/Output (HSIO) ports than Z97. While the latter had 18 such ports orts that could switch between the PCIe lanes, es, USB 3.0 ports and SATA 6Gbps ports, Z170 70 now has 26 ports than can be implementedted in a variety of ways.
This gives motherboard manufacturers greater ability to pick and choose what combination of connectivity options they’d d like to offer. For instance, the new Intel Rapid pid Storage Technology (RST) allows Z170 to support up to three PCIe devices at one time,me, which means that M.2 and SATA Express devices can be installed in RAID arrays as long as they are connected via these HSIO
