Hi, I'm currently in the process of upgrading my 4,1 dual to 5,1 with 2x 5690 CPUs, RAM etc. I've already read a lot here and tried to search for it better but can please someone confirm or recommend a solution? As far as I understand, the fastest speeds would come through the PCIe slots with NVMe. Unfortunately, all PCIe slots filled with cards I need for other things (2xDSP, sound + USB 3.0). That leaves me with the option to use either a drive bay or the bottom optical bay, which are slower. As far as I understood the speed should be equal on both though (SATA 2), is that correct? Is it still worth upgrading to an SSD at all then, and buy an older one or a newer SATA3? I'm looking to upgrade a boot drive for High Sierra or Sierra (?), audio drive and would like to do some video editing (HD not 4k yet). Any ideas and, if possible, recommendations on SATA2 drives if that's the outcome? Thanks for your help!
