If the disk is SMR (it probably is), then it will have 100GB-200GB CMR
write cache.
When you write, that is where the data goes. Later, the disk moves it to
the SMR part. So, each write is followed by the disk FW activity/clean up.
If you write more data than the cache size, without given the disk

I recently purchased a 10TB Seagate USB3 drive and it had an IronWolf SATA
drive in it.
I just did basic functionality tests and then shucked it. I trust the
IronWolf drives for reliability and will maintain an off site (encrypted)
backup as well, so the reliability of the drive is well within my c
I guess that you are hoping to find SATA drive inside the enclosure.
If true - you might be disapointed as a lot of these drives have native
USB interface under the hood - unless you already know otherwise.
Additionally - the drive is most likely SMR - so your test should take
that into account a
In my former life as a test engineer for a disk company, we used custom
testers to stress-test.
That eventually moved to custom code loaded directly on the device to do
the work.
When I moved to Linux we used direct-io libraries to write and read/verify
random or patterned data to the drive; in bot
