I currently have 4 NVMe SSDs in individual PCIe -> NVMe adapters. I will be converting to two Oracle F40 SSDs in order to save two PCIe slots while not losing any storage space. Would I be better off removing half the NVMe SSDs (they are in RAID10) or would I be better off backing them up or temporarily moving them to a CIFS share on a NVMe SSD on my desktop? There is one VM that has to stay running, my pfSense firewall.
