Red Pro 24TB NAS 3.5" Internal Hard Drive - 7200 RPM Class, SATA 6 Gb/s, CMR Recording Technology, 512MB Cache

Pricey but good quality.

Bought these for my NAS running Plex. Arrived quick, well packaged. Been monitoring them for a year in constant use and not a single issue. Not really much more you can say.

Not using this drive as a NAS but normal storage on my PC. This drive is quiet and quick and not getting hot in normal use. Easy to setup and format. No problems so far

Fortunately these arrived in a working state, unlike some others. But after months and months of trying to get these to stop making noise every 3-4 secs in a Asustor NAS, it turns out its own self protection is keeping the drive active even when the drive has zero data on it. FYI yes Asustor NAS have issues with SSD caching and Roon App issues which accesses all drives, I have never used or activated either. Wasted +£600 on noisy drives.

As described, arrived early and was securely packed. Not used as yet as I am waiting for a Nas enclosure to expand my network storage. This Hdd comes with a 5yr warranty and the project was the best at the time of purchase.

So, I recently intall the 8tb spinning disk into my home storage server. It's a pretty hefty drive, specifically designed for this kind of continuous operation. I've been testing it out for a while now, and so far, it's been a champ. No weird noises or slowdowns to report. I'm pretty pleased with how it's handling all the data.

If NVMe speed is not the driving factor rather a reliable backup is then these are a good alternative I run 2 of these in a RAID 0 set giving me 32TB of backup space and they are very good, Performance is surprisingly fast and as its just two disks after 4 years I'll mothball these as a backup of that day and pop in two new ones (in 4 years time that's more likely to be SSD). Today though with an inexpensive Enclosure its an inexpensive and reliable backup solution when you need high volume backups. I use these as a fast tertiary backup so Raid 0 is fine. I would never recommend Raid 0 as your only backup option.

Great stuff can’t go wrong with WD NAS

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.

Excellent as described

No issues after one week.
