When I’m adding a pile of SATA drives or building out a NAS, an LSI 9205-8i style HBA is exactly the kind of PCIe card that can expose lane-sharing problems fast. It’s a great expansion card, but only if you place it in a slot that has the lanes and bandwidth to keep storage from becoming the choke point.
