Used as a storage drive in my pc, files transfer fast so basically it's a nice and fair productOne only deficit is that it sometimes makes strange noises but this is just as rumored what WD high rev HDD would do, and it's not bothering when you are devoted in working/gaming

I never had any good experience with WD devices. One them caused me to loose 15 years of photos and personal work. This NAS drive works perfectly for now (for the last month). But I'm not sure what will happen after a few more months. For the price i've bought it, i can recommend it.And it works without any problem with WD Ex2 Ultra 2-bay NAS.

I ordered 6 WD Red Pro 4TB drives. When receiving the drives, I was appalled to see how poorly they were packaged. 6 drives is a low quality cardboard box. Each drive only "protected" by the anti-static foil, and a some paper to fill up the empty space in the box, with plenty of room for the drives to move around! Frankly, my butcher does a better job packaging sausages.Upon installation in a brand new Synology RS1221+ NAS it became clear that 2 drives were DOA! The drives were returned to Amazon, and 2 new drives were received. This time, packaging was better. Individual cardboard boxes with foam for each of the drives, and "airbags" for fill up the empty space in the box containing the drives. Unfortunately, 1 of the 2 drives was also DOA!A new replacement was again shipped with very poor packaging.Running a new check on all the disks revealed new bad sectors on 2 of the original drives.Conclusion: of the 9 drives I had in had, 3 were DOA, and 2 had bad sectors after mere weeks of running idle. An absolute unreliable disk!

Ongelofelijk, vreemd dat de pakketbezorger van DHL het pakket in de brievenbus deponeert en dat een harddisk in een kartonnen envelop word verstuurd. Nu maar hopen dat de harddisk nog (lang) werkt!Voor de rest is de harddisk goed voor mijn Synology NAS server. Helaas maakt de harddisk meer geluid dan een normale harddisk, en kan me voorstellen dat het storend is wanneer je een NAS server in de woonkamer hebt staan.

Van 2 gekochte disks 1 defect DOA (niet door NAS gevonden en een tik iedere 2 seconden) hoop gedoe om terug te sturen, na 1 week bedrag nog niet terug gestort...zag reviews helaas te laat, dat meer bestellers dit is overkomen. De producten zaten overigens wel goed verpakt....volgende keer betaal ik liever iets meer, bij de professional.

Lo compré en agosto de 2024 para un PC tipo torre (no servidor) y hasta ahora no ha dado ningún problema. Tiene buenas velocidades de lectura y escritura siempre teniendo en cuenta que se trata de un disco mecánico.

I bought two units of the 20TB version of this WD Red Pro drive for my new storage system. I particularly went with the 20TB version, because - according to the datasheet on Western Digital's website - it is less noisy than some of the lower capacity models.I tested one of the units, not in my storage system, but in my open bench USB 3.0 to SATA Adapter (with a max transfer rate of over 500MBps). It performed well, the sequential read and write speeds as high as ca. 270 MBps and ca. 130 MBps on the low-side. This is typical of all HDDs: on the outside of the drive they can pack more data on one track than on the inside, so on each rotation they can write and read more data on the outside area of each disk platter. The write and read tests were also successful, no bad blocks were reported. For some performance figures, please see the attached screenshots (which have the serial number removed/redacted). Please note that the CrystalDiskMark results are performed on an empty HDD, so they seem to be executed in the "fast" section of the drive. The other graphs were taken from HDSentinel, relevant there are the bottom graphs, which show transfer rates across the surface of the drive.The sound of my test unit was also pleasant enough, the clicking wasn't too bothersome. But since I will move this drive into the case of my storage system very soon, the clicking will be a lot less noticeable than it is already.One action I always perform, BEFORE opening the product box of an HDD or SDD is to check the serial number on the box against the manufacturer's warranty website to ensure that the item is covered by the manufacturer's warranty. I do this both when amazon is the seller and when a 3rd party is the seller and amazon is just the fulfillment party. (I do not buy HDDs from a 3rd party seller that does not have fulfillment with amazon.) This is to avoid OEM/gray-market units that aren't covered by the manufacturer's warranty. A store warranty by a 3rd party seller is of no use to me, since these sellers come and go and I also don't want the hassle of dealing with them. Since the Red Pro series offers a manufacturer's warranty of 5 years, and HDDs fail frequently enough to make such a warranty very valuable, I always insist getting the manufacturer's warranty and even will query 3rd party sellers, if their stock with amazon is covered by such a warranty.As it turned out, the serial number of second 20TB HDD that I ordered (from a 3rd party seller, since amazon themselves were out of stock) did not show up in the manufacturer's database for U.S. warranty, so I can only assume that it is a gray-market unit and I immediately returned it. (I can only hope that the 3rd party seller will have to bear the full cost of this return, since I emailed them and asked about the manufacturer's warranty, before the item ever shipped, but they didn't answer my question.)One more tip: There has been some research that failure rates of HDDs from the same batch are somewhat correlated, so I always try to space out my purchases (either in time or by using different vendors) to increase the chance that I will be getting units from different batches. That's why I bought from two different 3rd party sellers on amazon (one of which apparently sold a grey-market unit), without disclosing that fact ahead of time.

Excelente duración, poco ruido .

Keeps making scrubbing sounds at all time. Won't be suitable for use in a home NAS device, if noise is a concern.

HD durou apenas até o fim do período de devolução e estou pagando por um produto que não consigo utilizar. Não recomendo o produto.
