To say it again, another factor you need to consider is whether or not your ssd drives are PCIe3 or PCIe 4. It can make a big difference in transfer speed. I know that you can now get PCIe4 on motherboards, but I don't know anything about external enclosures. https://www.techspot.com/review/1893-pcie-4-vs-pcie-3-ssd/ Bill _______________________________________________ PLUG: https://pdxlinux.org PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
