I mean yeah, the bits end up where they should. It's just that the speed/progress indication is near useless with pv since at the end of the copy you still need to wait for the entire write buffer to be flushed (2 GiB in my experience, which can take several minutes).
So IMO
dd
with at leastoflag=osync,odirect
is safer thancp
andpv
with which a newbie might forget to runsync
and unplug the usb key immediately, so they'll be missing a lot of data.Maybe some people use
dd
for the wrong reason, it's their problem, but the solution is to usedd bs=4M oflag=osync,odirect
, not to usecp
.
