It’s a Hard Drive. It’s Big. That’s Pretty Much It.
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?

Rock-Solid 26TB WD Red Pro NAS Drive
I ordered the 26TB Western Digital Red Pro NAS internal hard drive, and it exceeded expectations right from the start. It arrived fast, was packaged securely, and installed without any issues. Once up and running, the drive performed exactly as expected—quiet, cool, and incredibly reliable. Transfer speeds are smooth, and it integrated seamlessly into my NAS setup. For large storage needs, backups, or expanding a home server, this drive is a powerhouse. If you’re looking for top-tier performance, huge capacity, and dependable WD Red Pro quality, this 26TB model is a fantastic choice. Would absolutely purchase again.

Serial numbers are OEM drives according to WD
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.

Highly recommended.
A nice addition to my NAS. Have a set that has been running continuously for over a year and a second set for several months now. If I had to complain about something, it would be that they seem a little on the loud side. The NAS is in the back room, so it is no bother. These WD Red drives are good for the price. The speed is good, storage capacity is ample. I expect many years of performance out of these drives.

Great quality
I get these for my husband's NAS since they're the most reliable brand. We've been using Western Digital for decades now, and this product is no different in terms of quality and durability. It fit right into the NAS and was easy to format. It looks great, doesn't stick out or anything, and was a great price. Definitely will be buying these again.

When Seagate Exos X24 fails... WD Red Pro NAS comes to the rescue!
I had one of my Seagate Exos X24 go bad on me after just 6 months, the other 3 are still functioning, but I didn't want to invest on another Seagate drive, so I went with Western Digital this time. It took about a week to deliver, packaging had one of the corners indented, the plastic shells don't really do much in terms of dampening vibrations. This drive is pretty hefty, so I'm always afraid it will be the damaged during transit. I went with the largest NAS drive I could find. Kind of sad I missed the 24TB for 440 bucks last week. Went with this 26TB instead for 500 bucks, shipped and sold by Amazon. Storage capacity and dependability is a must considering my NAS only holds up to 4 drives. This was easy to install and took a little over a day to rebuild my RAID 5 up to healthy status. Connectivity / bandwidth / noise levels / speed is very similar to my current Exos drives. I really hope this drive lasts me a good few years, hopefully much longer than the 5 year warranty. So, durability is still uncertain at this point. I can't say these drives offer great value for money simply because currently prices have only risen, which is sad. The main reason why I deducted one star is because I could not find a way to update the firmware on this drive. Unlike my Exos drives, which I successfully (but quite painfully did so on Windows 11, because of horrible command lines and poorly written instructions) updated from version 05 to 06 just a few days ago. I have no idea how to update the firmware on this WD drive. It would be nice if WD would make a tool to detect and flash a new firmware on these drives on Windows 11 automatically. Why is it so difficult for them to do something like that? I would tentatively recommend this drive for anyone looking for a nice and quiet drive for their NAS. Cheers!

Ho voluto provare la versione PRO , che ha una rotazione superiore rispetto al solito . Per quel che riguarda il prodotto in generale non ho nulla da dire .. gli hdd WD Red sono una sicurezza. Devo però esprimere un giudizio negativo sulla rumorosità , dovuta alla rotazione superiore . Ho il Nas sotto il mobile TV chiuso e nonostante tutto si percepisce il ronzio continuo del hdd....è parecchio fastidioso . Penso che in futuro acquisterò un Seagate che gira a 5900 per vedere se risolvo il problema rumorosità.

Excellent as described

J'avais commandé deux pièces et je les ai reçues très rapidement. Elles étaient bien emballées chacune dans une boîte d'origine de vente au détail. Je recommande ce produit pour installer dans un système RAID (NAS ou ordinateur avec un contrôleur RAID).

purchase limits on this thing are quite annoying, 3 X 26TB shipped to Australia from USA. Amazon price is literally 1/2 of what they are charging locally in Australia. All drives arrived in good condition. Amazon driver thinks its ok to leave $2500 of drives outside a house without even knocking/ringing bell. 5/5 Product. 5/5 Price. 0/5 Delivery.
