I ordered, upon delivery it had a cut or puncture in the anti-static packaging. The BIOS only detects the model, but does not learn more about it. In Linux, the kernel reports IDENTIFY_FAILED which is either a communication error (cable) or a HW failure. Since I connected another WD RED 8TB to the same cable and it worked without any problems, the fault would be in the HW - possibly a blocked platter after a crash. I put in a claim with Alza, and instead of settling the claim it was rejected, with the proviso that I should pass it on to an authorised repairer. Subsequently, the order was cancelled and the disc returned to Alza. I wouldn't be surprised if it goes on sale again..: -( The packaging is lousy, only in bubble wrap, and it's possible that it fell out of the carrier during shipping. As the disc is not a tea box, they should package and handle it much better. Based on the discussion, it's not a coincidence.
I don't know.
It's not working.

Looks like he should be good from the tests.
I bought (elsewhere) 4 pieces and one was defective from the start. So I don't trust him that much in terms of reliability anymore.

for me good, no strange noises, no vibration, does not overheat, after longer copying starts to work a lot for a while it is hear but probably some internal defragmentation I do not know works

I've been using WD Red Pro drives on a very busy NAS for a number of years and have been completely satisfied. I have them in RAID 5, but so far I have not had to replace a disk due to failure.

A robust, high-performance HDD.
Rating, stamina is top tier.
Unfortunately I had to return it because after plugging it in the NAS server turned into a rocket drive - extreme hum even without writing, extremely loud writing, server temperature 5-10C higher and vibrations.
The final choice is the WD Red Plus, which although rated lower, are not audible even when writing and their temperature is significantly lower.

WD was the favourite and the obvious choice. However, these discs have a high rate of "junk", probably from the factory. After more than 4 pcs have been inserted into the system, the NAS or the disk array of the camera system reports errors or. erroneous sectors without possible correction. The disk is then rejected by the system. Followed by a claim, replacement. If the disk boots up, it behaves half-way afterwards. But. the devil knows what's going on and what's going to happen next.

if it's up and running, then it's probably OK
large number of erroneous sectors after the first power-up
the disk is subsequently rejected by the system
