    • 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

    • Lots of storage for a good price.
Capacity: 10TB Style: Red Plus
Replace an SSD and a SATA drive with this one and I gotta say it's pretty good. I can't really say anything about noise since my office has a few systems with audible fans which I wouldn't say are loud but definitely not completely quiet. Transferring big files like zip or iso are really fast and big groups seems fast as well. Happy with the price and performance so far. Update... Was making a sound but I noticed it stopped when I held down my PC. So it seems like the drives rotates really fast and if parts in your case are just a little loose you will hear some noise. I opened up my case made sure everything around the drive was secured and so far no loud noise. ... show more

    • Excellent deal and product
Capacity: 8TB Style: Red Plus
I have a number of these drives in a server as well as in a NAS. I use them directly in a server for storage for a Media Center system. In the NAS they're powered up 24x7 whereas in the server they get powered up and down each day. I've not had any problems with them. The only reasons I keep buying them is because I'm upgrading from smaller capacity WD Red drives not because any of them have ever failed. This purchase was to create a USB backup device but I'm actually using it to replace a smaller 6TB drive instead. What made this even a better deal was buying it during the Amazon Prime Day and got a great discount on it. None the less, these NAS drives are solid and I now added them to other servers as Data drives (using SSD's for boot devices). Highly recommend them. ... show more

    • The drive is good BUT IT'S NOT COMPATIBLE WITH THE MAJORITY OF UNITS OUT NOW!
Capacity: 22TB Style: Red Pro
I was all. excited to buy qty 2 of these. I got them and found out they will not work with my Synology NAS as it only accepts up to 20TB. So I went to my attached USB 2 drive Terramaster and sure enough it also only handles up to 20TB. From my research the 20TB is really a limit until a newer generation of home server or USB multi drive. unit comes out.. Buyer beware.. My Synology could handle one of them but not two in a raid.. ... show more
