If it's a WD Red Plus on the label then it's CMR and good. If it's WD
Red without the "Plus" then it's SMR and WD has said don't use them
for this purpose. It's not impossible to run the WD Red in a RAID, but
they tend to fail when resilvering. If it resilvers correctly then it
will probably be OK at least in the short term but you should consider
getting a couple of Red Plus and having them on hand if the plain WD
Red goes bad.
Avoid WD ...
I've got two 4TB Seagate Ironwolves and a 8TB Toshiba N300.
I've also got two 3TB Barracudas, but they're quite old and I didn't
know they were a bad choice for raid. From what I can make out, Seagate
has now split the Barracuda line in two, and you have the BarraCuda (all
SMR) and FireCuda (all CMR) aimed at the desktop niche. So you might
well be okay with a FireCuda but neither Seagate nor us raid guys would
recommend it.
