Locating PP/AE files on drives

Hi guys. I wonder if there is any tutorial which describes how we should locate all Premiere Pro files, e.g. Media cache, scratch discs, footage and others files used in project, when we have more than one drive?
Right now I have SSD M.2 1TB + 2x SSD 250GB + HDD 1TB (as an archive) and I would like to get the best performance in Premiere Pro/After Effects with this setup. I found a few guides, according to which Media cache and Scratch discs folders should be located on separate drive. But what if we have drives with significant speed differences (Read/write of SSD M.2 = 3500/3200 MB/s, standard SSD = 540/520 MB/s)? 
Thanks for your help!
