    • Reliable Performance and Trusted Quality: WD Red Pro NAS 14TB Internal Hard Drive
Capacity: 14TB Style: Red Pro
Review Image by Edward Edward
I recently added the Western Digital 14TB WD Red Pro NAS Internal Hard Drive to my home NAS system, and it has proven to be a stellar addition to my storage setup. The drive lives up to the "Pro" in its name, providing reliable performance and ample storage capacity for my needs. First and foremost, the drive itself operates quietly, a feature that is appreciated in any home setup. While the housing I chose for the drive could use a bit of improvement, the internal workings of the WD Red Pro drive are where it truly shines. It seamlessly integrates into my NAS system, delivering consistent and efficient performance. Setting up a home NAS system with these drives was a breeze, even for someone with basic knowledge of storage systems. The user-friendly nature of the WD Red Pro series makes it accessible for those looking to establish emergency backups for crucial family information or simply expand their storage capabilities. Having opted for a total of 4 drives for my NAS, the storage capacity has proven more than sufficient for my data needs. The reliability and consistency of WD drives have been a constant in all my systems over the years, and the WD Red Pro series is no exception. It's a trusted brand that excels in the field of storage solutions. In conclusion, the Western Digital 14TB WD Red Pro NAS Internal Hard Drive is an excellent choice for anyone seeking a high-capacity, reliable storage solution. With the ease of setup and the brand's proven track record for quality products, it's a solid investment for both enthusiasts and those looking to secure their family's crucial information. I highly recommend WD Red Pro drives for anyone in need of professional-grade storage performance. ... show more

    • They just run and run and run...Synology 4112+ & Expansion Unit
Capacity: 6TB Style: Red Plus
Some techies don't like these. I do for my Synology 4112+ RAID Server. Not happy WD is pulling this Red PLUS nonsense, if you know, you know what I mean. Simply, the new basic Reds, look like the old better Reds, but are not. You want these, Red Plus, to replace the old ones. Had 3tb Reds before this - lasting over 11 years 24/7 - a lot or those years spent in up to 88 degrees in Vegas home with bad A/C, three of 4 were still running when I pulled the raid and upgraded to these 6gb drives (in a place with good A/C, phew). Tbh, I'm writing this review a year after buying 5 of them for my RAID server. They're doing great. Disc health is pretty much perfect still. ... show more

    • 1 DOA out of 4.
Capacity: 8TB Style: Red Plus
Bought 4 8GB for a NAS. Upon receiving them and putting them in, 1 was DOA. It happens, just be sure to try them as soon as you get them. No complaints otherwise. Solid HDD’s.

    • Works fine but let's talk about the "noise" that some don't like
Capacity: 2TB Style: Red Pro
This drive worked perfectly upon installation and I've had no problems with it in over 2 weeks. I'm using it for Time Machine backups via an external disk attachment on a 7 year old Mac. Time Machine runs about once an hour. However, I noticed that some reviewers are complaining about the noise on this drive and I want to use my IT professional background to give some insight into what might be going on for them so that others can make an informed decision on this drive. I have the 2 TB drive. I don't personally find this drive to be loud and it's running in an external disk drive enclosure. It runs about once an hour for however long Time Machine needs to run. When the drive is in use, it does make some noise, but it can't be heard at all outside of the room it's in. I sleep in the room next to where it lives and both rooms are always open and I've never had this drive make enough noise to be heard beyond maybe 7 feet from it and it can barely be heard at that distance. So why are some people complaining rather bitterly about how loud this drive is? First of all, it's an old school mechanical drive. It will make some noise when in use. That is the nature of these drives. And the more you use them and the more filled up they get, the more likely they are to make some noise on use. It is also possible that some drives off the manufacturing line are better than others, some are worse, and some of the people who complain just by bad luck got a noisy one. I don't find the noise I'm hearing to be unusual for this type of drive. I've heard a lot worse. Also, if someone is going to use this drive with a lot of file deletions and additions, it's going to make more noise. My suggestion for people who are extremely noise sensitive is to consider paying more and using SSDs instead. They won't make any noise. This drive has worked exactly as I intended it to work and I would recommend it to others. Again, please note that this is a mechanical drive and its lifespan is expected to be much lower than that of an equivalent SSD. You should probably think about replacing it after 3-4 years whereas for a 2 TB SSD, ,in theory you could get decades of heavy use before it goes bad. That's why SSDs cost more. ... show more

    • Loud Drive. Not same performance as Gold.
Capacity: 20TB Style: Red Pro
I had a Gold which I was/am very happy with, so this review compares the two. The drives are currently in the same machine, so I can compare real world performance. By the spec sheet, the only difference between the Red Pro and Gold is the MTBF. In my machine side by side, I've found that to be very untrue. The Gold is quieter and noticeably faster. They're all on the same SATA III controller. Gold gets 50 MB/s faster transfer when past the write cash. That's 20% which is a pretty big difference for a drive that's claimed by the manufacturer to be "the same" spec. for write. The Red Pro is very loud. Much louder than the Gold. In my Fractal case, the drive has so much torque that it rattles around in the HDD cage. Sounds like a woodpecker. A terrifying racket if your data is important. This is partly a product of Fractal's proprietary mounting system, but other drives didn't rattle. Fortunately, the Fractal case has alternate places to mount it, so I was able to put a stop to that. For the price I got them at, I would still buy again. But I would have liked to know that: yes these are not as good as the Gold in every dimension. ... show more
