I run 5x Seagate IronWolf PRO 4TB and 1x WD Red Pro 4TB. I wanted to try just a different drive and I'm not too excited about it, or I didn't give it a look at the user reviews below. I also bought the Alza product "Instant Replacement Guarantee" for ~400 CZK, which guarantees a replacement within 48 h in case of a claim. Nothing happened for 4 days after the complaint, so I wrote to them. The answer was that they had to technically verify the disk first. So we exchanged a few messages and on day 6 my new disk arrived (which is working so far). For me, disappointment from WD and from Alza (I know that 6 days replacement is great, but if they offer a product with a 48 h guarantee, they should replace it and then think if it makes sense for disks)
The very first piece I received was non-functional from the factory. I just booted up, ran the smartctl test, which didn't run. That's all we could do with him.
Noisy during enrollment.
The "immediate replacement guarantee" doesn't quite work here.

I have it in both NAS and PC. It' s very fast and a bit noisier (but I rather like listening to it play). I had it in a NAS (2x 4TB) and my wife, while watering a nearby flower, dripped some water directly into the NAS, which has a ventilation grill on top (and bottom) and the disks are not protected. Immediately one HD left, so I ordered a new one. Even drying with a hair dryer didn' t help, the disc was kaput). That' s when I realized how vulnerable the drive is, and with it your data. After replacing it with this disk, it immediately caught on in the NAS, the recorded applications also worked (e. g. antivirus, DLNA server, FTP, etc. there are about 12 of them). I also have it in my PC where it acts as a fast disk for a lot of data. it rattles audibly there, probably because it resonates in that tin box (I can' t hear it in the NAS).
I have it for a short time, it works fast
is a little noisier

I don't recommend having it sent to an alza box either, it goes in an antistatic bag without any security.
I picked up with personal collection at the central warehouse and the discs were perfectly fine (after previous experience with shipping I didn't risk it anymore)
Quite quiet operation
Fits great in my NAS

I'm still testing, but definitely faster and quieter than Purple. transfer the same files to Purple for hours and to Red for minutes. I don't know if Purple was defective or such a feature, but never again. The advice from the Alza technician on the Purple's noise level must have been from a faux blonde "the drives are noisy and the SSDs are not" so I returned the PURPLE 24Tb and bought a RED.

Speed OK
It heats, but a lot. >10 degrees compared to the Seagate in the adjacent slots - therefore it burns and for that star down
Loud enough

I hope that the drives will still be as reliable as ever, I'm just sorry that WD started to add firmware that is not compatible with the previous version S. M. A. R. T. I hope there's not some hidden villain in there.

The 8TB WD Red Pro, which I have had for a couple of years now, is problem-free
classic CMR notation
Unfortunately, the new 8TB Red Pro WD80005FFBX series got a new S. M. A. R. Firmware that my decade-old NAS no longer understands. It is not possible to perform a preventive check of the state of the S disk. M. A. R. T.
