I posted this in another thread I started but I don't thnk many saw it so I'm starting a new thread now. I currently have a 512gb toshiba ssd in Bay 1 of my 2009 Mac pro which I flashed to 5.1. My understanding is it is bottle necked at 3gb. So I'm looking at 1. https://www.amazon.com/Lycom-DT-120...00MYCQP38/ref=cm_cr_arp_d_product_top?ie=UTF8 pcie adapter to go with https://www.amazon.com/dp/B07C8Y31G2/ref=twister_B07CY4L25D?_encoding=UTF8&psc=1 samsung 512bg 970pro ssd or this samsung ssd https://www.amazon.com/Samsung-512GB-V-NAND-Solid-MZ-76P512BW/dp/B07836C6YV with this pcie adaptor that can hold 2 of them https://www.amazon.com/gp/product/B0096P62G6/ref=od_aui_detailpages00?ie=UTF8&psc=1 Is one preferable over the other as far as actual drives or type or adapter? Is one faster and which PCIe slot does it need to be in?
