I've filled up my motherboards 8 sata slots and now I'm looking for an HBA to get 8 more. Alas, I've only got a pcie 3.0 x8 physical with x4 electrical. I'm planning to expand my zfs pool and now I'm wondering if there are any serious bottlenecks having only 4 lanes would entail.
It seems as though LSI pcie 2.0 x8 cards are the cheapest so I wouldn't mind if one of those would work without any speed losses in this regard.
If that isn't a viable option, maybe a pcie 3.0 card running on 4 lanes would at least be equivalent to pcie 2.0 running on 8?
Anyways, my goal is primarily to find something on the second hand market.
