Useful to know.

Next question: how to find out whether a WD hard drive is plain old disk
SMR.

I bought a pair of 1GB WD Elements at the beginning of 2019 for use as
weekly backups that are kept offline when not actually doing a backup.

I'm using rsync to back up 4 computers (3 running 64 bit Fedora, the
fourth is an early 512MB Rpi B) so all other things being equal, I'd
expect to see backup activity to be pretty consistent for each machine,
which is what I'm seeing: in no case have I seen the sort of slowdown
which is apparently noticeable with SMR disks.

So, my guess is that these are not SMR, but who knows: I haven't found
any indication of drive technology in the so-called data sheet for for
these drives on the WD website - just a not that WD feel free to mix and
match drive type between production batches.

Is there any other site that would know/admit what type of drive is in
these WD Elements sealed units?
