I'm looking to upgrade my server's storage. It currently has SATA SSD storage but I would like to add to it an even faster PCIe3 SSD. It's a full tower with a few empty PCIe3 slots but no PCIe3 backplane, the motherboard model is Supermicro X9DR3-F. 2.5" PCIe SSDs are significantly cheaper than SSDs with PCIe3 card form factor. Is there a way to add a 2.5" PCIe SSD despite this motherboard not having the right disk backplane?
Assuming you are buying U.2 form-factor NVMe SSDs, then you could get something like this PCI adapter card, which let's you fit a 2.5" NVMe SSD into a PCI-e slot.
