It's funny that we discuss IDE drives at all. They stopped being
manufactured a decade ago and are not supported by modern chipsets or
boards etc[1]. I've been meaning to do something about that, but I
didn't have enough round tuits to research what to write about current
storage technologies... but also in the case of FreeBSD, it doesn't
let you turn the write cache on and off with nvmecontrol yet, but
someone has a relevant patch out (D32700) so I was also waiting for
that to go somewhere before writing in...
