Western Digital Purple 8TB Surveillance 3.5 Inch SATA 6 Gb/s Hard Disk Drive with Allframe 4K Technology - 360TB/yr, 256MB Cache 7200rpm - WD82PURZ

States 7200rpm but is actually 5640rpm

I have bought 4 of these drives. The first a 4TB was nice and quiet for five months then started making the loud clicking noises. I changed it and paid for an 8TB. Like the 4TB it arrived in a thin foil wrapper and a snug card envelope. No bubblewrap, box, nothing. It made grinding noises and was like sitting on an aircraft listening to the air-con. I exchanged it for another 8TB and it too was poorly packaged and noisy with constant clicking. Amazon tech said the 8TB ought to be as quiet as the 4TB; however, a closer look and 4TB runs at 5400 rpm, but once you get to 8TB they jump to 7200 rpm, which has to be noisier. I gave up and ordered a 6TB (biggest at 5400 rpm) in the retail packaging and some other items to guarantee it also came in a larger box. 6TB is as quiet as the 4TB, but I will not gamble with the cheaper one with the zero protection again.

Ok for a star the drive works...It's going in an Unifi Protect 4 bay NVR. It will be part of a raid5. I still need to test it.I'm just so cross, It turned up late. It was packaged without even bubble wrap.So I don't have a lot of faith in it lasting. see image.Next time I would buy from someone els.
