Yes I am seeing some similarities in threading model for sure.
That said, there are a lot of other simultaneous considerations at play when we are talking about punching through business entity storage rates that exceed the rated IOPS capacity of the underlying storage medium. My NVMe test drive can only push ~500k write IOPS in the most ideal case, but I am able to write several million logical entities across those operations due to batching/single-writer effects.
So depending on the disks, we found that different IO sizes will yield optimal settings for saturating disks. As an anecdote in clouds, the IOPS is the key principle and often you can drive higher throughput depending on your DMA block size (i.e.: 128KB vs 16KB etc)... obviously a tradeoff on the memory pressure. but you can test them all easily w/ `fio`
