Thanks for the links!
I was wondering if bcachefs is architectured with NAND-flash SSD hardware in mind (as recently highlighted on HN in the "Is Sequential IO Dead In The Era Of The NVMe Drive" article [1] [2]), to optimize IO and hardware lifecycle.
Skimming through the "bcachefs: Principles Of Operation" PDF, it appears the answer is no.
