I am preparing to install a recently purchased HBA (LSI SAS 9202-16e), it is designed to use a 16x PCIe 2.0 slot which has 8GB/s bandwidth. Since an 8x PCIe 3.0 slot also has 8GB/s (7.88) bandwidth would the card still be able to reach similar performance? I am looking at running 16 3.5" 7200rpm HDD's off this which are running in a Storage Spaces parity array (will be 32 in total across 2 cards). I know array performance isn't fantastic in this setup, however it is about data protection and not speed (Plex media only). I do have 2 16x slots available, however it would mean I would need to move my GPU to an 8x slot which is in a custom hard line loop, as you can image if I can avoid this I would prefer to. Apologies if this is a stupid question, I wasn't quite sure if just the bandwidth is what I should be looking at or whether there were other factors to take into consideration here.
