I need to think about this for a second.
You’re saying the performance gains stop at two drives in raid striping. RAID10 in two strip two mirror would still bottleneck at 8 total lanes?
I also need to see about the PERC being limited to 8 lanes - no offense - but do you have a source for that?
Edit: never mind on source, I think you are exactly right [0] Host bus type 8-lane, PCI Express 3.1 compliant

To be fair; they have 8GB NV RAM, so it’s not exactly super clear cut how obvious a bottleneck would be.
