So you can copy/backup/move disks and partitions without worrying about
whether you can get access to the result in the future? Because you
don't want to trust or rely on

My initial post was indeed a little light on details, so here's more info:

Hi all,
First off, I realize this question has been asked here and elsewhere

In short, the write speed plummets to around 160 MB/s, as opposed to 270
MB/s on the naked partition; read speed is at 115 MB/s (slower than writing
- no idea why), as opposed to 465 MB/s on the bare partition. (I've pasted
the results below.)
