However, I've already seen 52c on the drive inside the enclosure! Around 70f room temperature, and the enclosure was warm, not hot, to the touch.
I'm going to shuck it before running badblocks (takes 6-7 days to run) in hopes it helps the temps.
Once installed I try to keep my drives under the low 40s. Is it possible I got a bad one, or are others seeing similar temps?
Seems like normal/expected temps.
edit
I pointed a fan at the drive and temps dropped to 44 C.
If you are patient you should be able to get a deal on Red Pros. Back in July I got a 18tb Red Pro for $240. The Red Pros come with a 5 year warranty; don't need to be shucked and are built/designed for NAS usage.
Random question, do these externals support UASP [startech.com]? In my experience, Seagate externals do not but most WDs do. UASP makes a huge difference in transfer speeds via USB 3. Without it, I average around 150MB/s and with UASP I get around 450MB/s.
FWIW, I've never had a problem getting an RMA on WD shucked drives, but it's a good idea to keep the enclosure just in case. Plus they can be useful.
You lose some space for the file system formatting, but that's a different issue.
I think Apple uses the same measurement as the drive manufacturers.
This article does a pretty good job of describing what's going on for anyone who's interested.

Edit - that person with the downvote must have gotten their bubble burst. "Wait, my $35 BOSS amp doesn't really put out 9000W from my car's 80A alternator!?!"
Sorry bro.
That was a fun little debacle on the heels of the CMR/SMR stuff.
i've not heard any good rumors yet

These,,,, all of these will run at 225MB per second minimum, but then your data changes from pictures to video, expect that big V in the data stream. I mean, what are you kids worried about? It's the same old as it ever was!

Some lower testing speeds here for the WD180EMFZ where they discuss a fun little bug where kicking off a short test actually inflates drive performance for a while. https://www.reddit.com/r/DataHoar...30_f

I own three of the 16TB WD essential drives, all of them will sustain 225 Megabytes per second, or greater, period! Sounds like you may be thinking too much and not asking enough real questions!
But what do I know?
Cheers 🍻

If you have a mostly empty drive and are transferring large files, the performance will be much better.
These are clearly going to be used for storage so I don't think any of it matters anyway, but there will for sure be times where drive transfer rates dip below that mark. The reddit thread I linked had a badblocks test running and they were averaging 185MB/s on 4x 180EMFZ drives. Not terrible, but below your threshold of absolute minimum.

Yes drive performance will dip into a V depending on the media. But general overall every time transfer speeds with these USB drives, will be, about 225 Megabytes Per Second. I did not tell a lie!
Being mad about it, don't make it slow or fast. Just makes it a point of contention.

You're not technically wrong but you're going by speeds that don't take into account the random IO delays of fetching multiple small files. Yeah, if you only transfer one or a few large files then the performance should stay above approx 225MB/s but real life doesn't normally work that way. That's why drive testing tools let you adjust file size samples.
My only point was that you can and will see real-life performance much lower than 225MB/s once you introduce IO delays because you're moving a bunch of small files. If you only ever move large ones.... you'll be fine.
No one here is mad, that's also a weird thing to bring up when you started your post (that I replied to) by telling everyone to shut up.
