Review on 🛒 MZHOU PCIe 1X Interface 3.0 10 Port SATA Card - Includes 10 SATA Cables, SATA Power Splitter Cable, and Low Profile Bracket - 6Gbps SATA 3.0 PCIe Card, Supporting 10 Port SATA 3.0 Devices by David Carter

Works with Unraid Out of the Box! Some previous reviews of other PCIE adapters said they worked or didn't work with Unraid, but my guess is that with the latest updates this card is up and running. I didn't get the 8 port card because it was out of stock but I chose the 6 port card and all 6 ports are occupied and working properly and are recognized in the OS with no raid. No issues with iommu or connectivity. UPDATE 04/30/2021 = Still working without problems. Even had a disk failure and replaced rsync parity and backup and worked.
