    • It’s a Hard Drive. It’s Big. That’s Pretty Much It.
Capacity: 18TB Style: Red Pro
So, here it is: the Western Digital 18TB WD Red Pro NAS Internal Hard Drive — aka the “Big Boy” of data storage. What can I say? It’s a hard drive. It’s quite big. Like, “I could bench press this if I really wanted to” big. But please don’t — it’s expensive. 18 terabytes of space means I could theoretically store every embarrassing photo, weird Spotify playlist, and downloaded PDF I’ve ever made. The digital equivalent of a hoarder’s dream garage. Installation was straightforward: slot it in, screw it down, pray to the tech gods it spins up on the first try. Spoiler alert: it did. No strange noises, no smoke, just pure, reliable mechanical magic. Pros: So much space, I could hoard cat videos for decades. Designed for NAS, which means it’s the responsible adult of hard drives — steady, dependable, and ready to work overtime. Quiet enough that I almost forget it’s humming away, plotting how to store my entire digital life. Cons: It’s heavy. Not “drop on your foot” heavy, but “maybe I should use two hands” heavy. No flashy lights or cool holograms, just good old-fashioned spinning platters. Does not come with a personal assistant to organize your files or delete your bad decisions. Final Verdict: ⭐️⭐️⭐️⭐️⭐️ – 5 stars. It stores data. It’s big. It doesn’t complain. Honestly, what more do you want from a hard drive? ... show more

    • Reliable Performance and Trusted Quality: WD Red Pro NAS 14TB Internal Hard Drive
Capacity: 14TB Style: Red Pro
Review Image by 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

    • Serial numbers are OEM drives according to WD
Capacity: 20TB Style: Red Pro
My 1 star does not reflect the drive as the drive worked perfect, Here is the problem that resulted in a 1 star rating, The drive was received in a new sealed WD Red Pro box with the 5 yr warranty sticker on the bottom but when I registered this drive in my WD account, WD flagged it as an OEM drive with NO WARRANTY. I talked to WD and they stated that the serial number on the drive which matched the serial on the box was an OEM drive , after sending pics of things they wanted to see they opened a case which is still open after 3 business days, Now, here is the real scary thing, this happened several days after I had bought same drive from Amazon and found out the serial number was also an OEM drive yet packaged in retail box. 2 20tb red pro drives bought within a week came up as OEM drives with no warranty, If you have bought this drive from Amazon, you better register it to check serial number is a retail drive or you got a $400 drive with no warranty. I have bought similar WD drives from Amazon and they were all fine so I have to assume WD screwed up things in their computer when they sent these retail drives to Amazon. ... show more

    • As advertised. Deployed into Synology DS920+ with minor (artificial) kink
Capacity: 16TB Style: Red Pro
These took under a minute each to install into my Synology DS920+ NAS. Since it was all new gear, I let it do a through drive check as part of initializing which took a long time. I think it may ave been about two days. In theory, I could have used it during this time, but I just started it and ignored it. During installation, the 920 whines about any accessories (memory, drives) that aren't Synology's own and that included these. On the 922, they change from whining to much more obnoxious contrived incompatibilities, but this combination was chosen because exactly once, during insteallation, it warns you that its not a supported combination and that's that. Probably if there were a support issue involving data loss, they'd remind you of that oath you took to not complain, but in reality this is a very common combination that works quite well. Fan and normal noise is quite minimal. There was a noticeable clunk during a head seek. I reduced this by offlining the unit so I could remove power then applying the fuzzy half of a hook-and-loop fastener to the bottom of the bottom rail. That gave it support and a little bit of padding so the metal cage didn't serve as a drum skin for the oh-so-tiny motion that got amplified when transferred to the sheet metal. I'm looking forward to getting many, many years from these drives, like I did from the 4TB WD these are replacing. Those drives have no reading errors. Size grows and no drives are infallible, so I opted to replace them on my schedule (OK, and on Amazon Day special. :-) ) instead of letting the drive pick its own replacement day, taking my data with it. ... show more
