So I am currently building my first build and I pretty much have everything completed with the exception of the SSD drive and or Harddrive. My MB is EVGA's Classified K Z170. My graphics card is already installed which is covering the first m.2 slot which is a 110mm m.2 slot. I didn't know if it was best to use this slot first but had a later thought that it would be better to use the 2nd M.2 slot which is the 80mm m.2 slot sitting just below the graphics card to have better airflow. But I didn't know if the slot made a difference on speeds. There is no indication on manuals or searching on Google about it so I assume not but I'm no pro at this so I would figure I would ask first. I do plan on using Sata also at some point and maybe even a hard drive. I know that depending on which m.2 drive I use I cannot use certain sata ports. My second question is if I do end up using the 80mm m.2 slot and also any available sata ports for extra ssd is it possible to also run a hard drive? I will thank anyone up front for reading though my ignorance and taking the time answering my silly questions.
